1 INTRODUCTION
1.1 MANUAL GENERAL DESCRIPTION
The purpose of this manual is to describe the interfacing to the machine tool., the hardware installation and the diagnostic of a
FIDIA Numerical Control. This manual is intended for the Machine Tool Manufacturer specialist who is experienced in
connecting electrical and electronic devices to machine tools.

The manual is divided into sections dedicated to the various purposes or users.
• The INTRODUCTION Chapter lists the environmental specifications of the numerical control.
• The MECHANICAL DRAWINGS Chapter contains information on mechanical interfacing requirements.
• The ELECTRONIC SPECIFICATIONS Chapter shows the electrical interfacing requirements and I/O pin assignment on
Fidia interfacing boards.
• The WIRING MODULE Chapter is dedicated to the wiring modules, for modular and simplified wiring.
• The CNC BASIC SYSTEM Chapter describes the type of signals available for interfacing axes, spindles and miscellaneous
functions; in addition, the coded names of the signals are shown, as listed on the document generated by the C_GEN
automated generation program (PNCnnnn.INT).
• The following Chapters describe the Options as reported in the Table of contents.
• The APPENDIX A describes the modes for displaying the status of the signals exchanged between the Machine and the
Numerical Control, before the Control itself is in operation and with the Numerical Control in operation.
• The APPENDIX B describes the internal connection for the Numerical Control.

Fidia NCs are supplied factory configured for the application for which they are intended. Furthermore, while being configured,
every NC is bench tested for each individual function.
This manual is intended to facilitate the installation of products that have undergone this procedure.

IMPORTANT
The descriptions, examples and illustrations contained in this manual provide a general indication of the installation and use of
the FIDIA Numerical Controls.
For the information contained in this manual to be used correctly, a knowledge is required of both the basic operating modes of
the Fidia control and the specific characteristics of the machine tool on which the Fidia NC is installed.
Fidia reserves the right to modify its hardware and software products without prior notice and shall in no way be held
responsible for any direct or indirect damage caused by the use of its products or by any inaccuracy of the documentation
supplied. No information shall be divulged to third parties, and this manual shall not be reproduced in whole or in part without

1.2 PRELIMINARY MACHINE TOOL CHECKS

WARNING:
Prior to powering on the machine tool, the following components must have been completed and tested:

A) On board plant: The limit switches, electrovalves, motors, hydraulic and pneumatic cylinders, position
transducers, emergency pushbuttons, photocells, control pushbuttons, indicator lamps, acoustic and luminous
warning signals, displays and any other machine tool equipment must already have been connected to the
electrical components. The connections and the connected devices must have been tested individually and

WARNING
Prior to powering on the CNC, it is necessary to perform several operations as
described in the installation procedure. If these are not carried out, the
following risks may be incurred:
personal injury and damage to costly equipment; delays in starting up the machine
tool because installation was not carried out methodically.

1.3 MACHINE TOOL BUILDER'S SAFETY PROVISIONS
For the present purpose the over-all machine plant can be summarised as in the figure below. It can be seen that, although
most of the interface logic is normally implemented inside the CNC by means of a PLC program written in the AUCOL
language, the machine tool builder still needs to develop its own additional logic (labelled as "Machine Magnetics" in figure).

Although small, this logic section is of vital importance from a safety stand point. It is compulsory and also prescribed by most
common standards, that any interlock having safety implications must be implemented as directly as possible. It must not go
through a complex piece of equipment such as the CNC, in which the possibility of malfunctions cannot, of course, be
excluded.
Therefore, with the present paragraph, FIDIA intends to convey to the machine tool builder some important advice concerning
the safety related criteria the latter should follow in the design of its own logic. It must be clear that FIDIA declines any
responsibility for any inconvenience deriving from any form of non compliance with the following indications.
To further emphasise the importance of this topic, it is worth remembering that the present evolution in machine tool design,
characterised by ever increasing speeds and accelerations, inevitably brings about a higher level of risk, which must be
accounted for with more comprehensive safety provisions. One particularly critical situation, which is becoming quite common
nowadays, is that of vertical axes without counterbalancing. In this case it is of course necessary to make sure, beyond any
possible doubt, that the axis brakes are active ( de-energised ) whenever the axis drive is not active.
In the following diagram we lay down our proposal for the machine tool builder logic. The implied safety provisions are further
clarified by the following comments:
1) The 1KA7 relay is de-energised and the brakes are clamped whenever UDCMA or any other emergency contact opens (or
when the Emergency Stop" push-button is depressed ). No matter what happens the machine then remains in the
emergency condition until the "Emergency Reset" push-button is depressed.
2) The brake relays 1KA12 and 1KA13 can be energised and the brakes released, only if the “Drive Ready” contact in the axis
speed drive is closed, meaning that the speed control loop is also closed. We advise to carefully verify the real meaning of
“Drive Ready” contact with the drive supplier.
3) The Aucol logics must constantly monitor the signals DIA*P and DIA*P1. Should any one of them be at 1 when UDSA* is at
0, (which means that the 1KA12 and/or 1KA13 contacts are short-circuited) the CNC drops UDCMA thereby generating an
emergency stop.
4) It will be noted that, in the diagram we have assumed the axis to be equipped with ball-screw as well as motor brake (as a
safety provision against belt breakage). Should only one brake be available, we still suggest to use two brake relays so as
to be able to detect a contact fault of any one of them.

1.7 ELECTROMAGNETIC INTERFERENCE SUPPRESSION
1.7.1 COILS SUPPLIED WITH DIRECT CURRENT
A diode should be placed in parallel with the cathode towards the hot end, for each relay coil driven directly by a numerical
control contactor and for each "power" coil, solenoid valve and el ectromagnetic switch, so that no current flows through the
diode when the coil is energized.
The recommended characteristics for the diode are as follows:
• Inverse voltage > 2 V d.c.
• Average current > ½ V d.c./Rbob (Rbob: ohmic resistance of the coil).

For example if V d.c. = 24 V Rbob = 420 Ω

• Average Icc > V d.c./2Rbob > 0.029 A.
• Inverse voltage > 48 V

Diode connection

1.7.2 COILS SUPPLIED WITH ALTERNATE CURRENT

The RC group must be connected in parallel to each coil as shown below. R and C valves must be selected in such a way that:
V = nominal voltage of the relay, electromagnetic switch, solenoid valve, etc.
P = nominal coil power
hence:
2
R ≅ V /P (Ω)
C ≅ from 200/R to 300/R (nF)

The resistance R must dissipate a power >= P/250 while C is the alternate current capacitor for an operating voltage that is
twice that of the supply (V).

1.8 DYNAMIC CHARACTERISTICS OF AXES

A T T E N T I O N - P L E A S E !
Recommendations concerning the dynamic characteristics of an axis.
In order to make good use of the system as a numerical control and/or copying machine, the following hints may be helpful.
The design should aim to obtain an axis calibration which allows a step response with at least the characteristics given in the
following figure, where a step voltage given in the reference signal corresponds to 1/4 of the maximum speed and a resonance
factor Q = 1.1 and a rise time Ts = 20 ms.
Furthermore, it is recommended that:
• given a step pulse ranging between 50mV to +50mV (and vice versa), the time for the system to react is less than 200ms
• the driver linearity is within 0.01%
• the speed drift is less than 0.1% of the maximum speed.

Step response

If the tracer is mounted on a supporting arm, it is necessary to guarantee that the vibration frequency of the system is
considerably higher than the frequency of the system.

In practice, this is obtained when the supporting arm has sufficient rigidity to allow for a deflection of less than 0.05mm when a
force of 50 Kg is applied to the end of the arm.

3.6 DIGITAL POSITION TRANSDUCER SPECIFICATIONS

This paragraph describes the electronic specifications of digital position transducers.
Due to cable length and size, the power supply for external amplifiers may decrease excessively, resulting insufficient for the
transducers.

3-12 MDO1384 FIDIA

If a wiring module is used, and the connection is made with a round flat cable, and auxiliary couple of power cables may be
necessary (see DCB*W sections ), running between the connector DC_AUX on the C1.f rear panel and the wiring module (or
EXE-like box).
The following graph shows how to evaluate the additional power wire diameter and length related to the theoretical current
requirements of the transducers; the “AWG” curves refer to the flat cable only; the other curves refer to additional wires.

When using a round flat cable for connecting the C1.f to the wiring module, the additional wires run in parallel.
The resistance of the cables should be computed according to the formula:
Rtot=2 l Ra Rc / (Ra + Rc)
where:
• Ra corresponds to the resistivity of the n.3 wires of the round flat cable (ρ ≈ 75Ω /km );
• Rc corresponds to the resistivity of the additional cable running in parallel;
• l is the cable length (one way)

The maximum voltage drop (measured on the wiring module plug) across the cables should result ≤240mV.
With 5÷6 digital transducer configurations it is suggested to supply each wiring module with its own couple of additional cables,
avoiding jumpering on Phoenix plugs.

Further:
• The maximum current for the transducers of all the axes must be lower than 3 A.
• The following figures show the timing features of the differential channel.

FIDIA MDO1384 3-13

The time "T" from the edges of the two channels "1" and "2" or the reference pulse must be longer than 250 nsec.
Maximum frequency: Fmax. = 1 MHz.

The maximum speed of the axis (Vmax) should be: Vmax <= 4R * Fmax

With: Vmax (Speed) in m/s

R (Resolution) in µm
Fmax (Frequency) in MHz
The recommended RESOLUTION "R" values are as follows:
0.5 µm
0.1 µm
1 µm

There are two formulas for calculating the Resolution of position transducers:
• with Rotary transducers: R = { 360° } / { 4 PX }
• with Linear transducers: R = G / { 4 X }

where:
P = number of periods per revolution.
X = fold subdivision of the pulse shaping electronics: EXE interpolation (see Heidenhain preferred devices table).
G = Grating pitch.
The number 4 indicates the evaluation of FIDIA electronics (x4).

Example:
for RON 255/18000 + EXE610 x 10 -> R = 360° / {4 * 18000 * 10} = 0.0005°
for LS 406 + EXE602E x 5 -> R = {20µm} / {4*5} = 1 µm

The power supply for all types of position transducer is +5 Vd.c.

For more details, please see the relevant Heidenhain documentation.

3.7 CPU5/CPU6 - POWER PC BOARD

The CPU board is an expansion board for the PCI bus that houses a microprocessor system based on the Motorola Power PC
chip MPC8240.
There are two models of CPU: CPU5 (150 MHz) and CPU6 (250 MHz); the interfancing and diagnostic are the same for both.
Communication between the PC and the Motorola system takes place through the PCI interface of the board.
The PCI bus guarantees data exchange between the PC system and the Motorola system at a speed of 132 Mb/s.
The CPU board is interfaced to the other numerical control boards through the PBUS (peripheral bus). This is an asynchronous
bus.
The CPU board implements an interface for 4 trigger probes and for 4 digital outputs reserved for the tracers.

3.8 CPU CONFIGURATION

Standard configuration of the CPU board

Do not alter the standard configuration of the board.

3.8.1 FIRMWARE
The CPU is equipped with firmware for initialization, diagnostics and for system debug/test functions. Firmware loaded into the
flash memory of the board:
• Boot (BOOT)
• Start Manager (STMAN)
• SID

BOOT
The Boot program performs a partial initialization of the CPU and, if there are no problems, it passes control to the Start
Manager. The purpose of the Boot is to have a minimum operating firmware that allows for an upgrade of the Start Manager in
the event of problems. The flow chart below shows the operations performed by the Boot.

NOTE:
• If the Boot program is damaged or if the flash memories are cleared, the board cannot be programmed by means of the
utility software but must be re-programmed using an external device that is connected to the CPU.

• If the CPU has remained in Boot mode (phase b2), SID cannot be upgraded using the "PowerPC Loader" utility. In such
cases, an attempt can be made to upgrade the Start Manager from "PowerPC Loader" in order to enable the board to go
on to phase P2; SID can subsequently be upgraded.

FIDIA MDO1384 3-19

BOOT Flow chart

START MANAGER
The Start Manager performs the complete initialization of the CPU and of the boards contained in the system (MFB1, axis
boards). It also performs a diagnostics test of the hardware and initializes the memory areas for the exchange of information
with the NC.
Once these operations have been performed, the board stops at phase P2 and waits for the application to be run on the PC
(CNC User Interface or Maint).
The flow chart below shows the operations performed by the Start Manager.

Start Manager Flow chart

3.8.2 DIAGNOSTICS
2 LEDs and 2 displays, located on the I/O interface connector side, are used to diagnose any problems or malfunctioning.
LED DL1 (R) indicates the status of the /RESET signal of the board. If the LED is illuminated, this means the board is blocked
in the reset state.
LED DL2 (E) indicates that the LP146 programmable logic has not been loaded. If the LED is illuminated, this means that the
EPC1 serial EEPROM (U21) has been unable to transfer data to the EPLD (U10). In such cases, the board remains in the reset
state.

FIDIA MDO1384 3-21

 LEDs and displays

The displays are used to show the various phases of execution of the firmware and the error codes. Below is a list of possible
codes that can be displayed and their meaning.

NOTE:
The decimal point in display 2 is lit for all messages provided by the Boot, Start Manager or SID.

Boot status messages:

b0 MEMORY TEST
The memory used by the BOOT and STMAN programs is quickly tested during this phase. In practice, the first megabyte of
RAM memory is checked.

b1 BOOT CODE RELOCATION

During this phase, the boot code is copied into the RAM memory and executed from this.

b2 INIT BOARD
During this phase, a first partial configuration of the board is executed before control passes to the STMAN program.

Start Manager status messages:

P0 INIT BOARD
During this first phase of the STart MANager, the complete configuration of the DRAM controller and of the processor
peripherals is executed. Then the second megabyte of RAM memory is tested, and the STMAN code is copied from the flash
memory to the RAM memory. If no errors occurs, STMAN goes on to the next phase.

P1 SYSTEM INIT & TEST

The complete initialization of the system (peripherals, PBUS boards, SID/CN data memory areas) is carried out during this
phase. In addition, a functional hardware test is performed as part of this phase.

P2 WAIT COMMAND
Once initialization and the tests have been carried out, the software stops at this phase and awaits a command from the
application running on the PC. Applications that can be used are the WS interface for NC, the MAINT debug utility or the
"PowerPC Loader" flash programming utility.

P3 RUN SID
If the Maint application is run, the Start Manager goes on to this phase and copies the SID firmware from the flash memory to
the RAM memory after checking the checksum.
If there are no problems, control of the board passes to the SID application.

P4 RUN CN
If the WS interface is run, control passes to the NC code loaded in the RAM memory of the CPU board. The NC code and data
are loaded in the CPU by means of the driver and the WS application loaded in the PC.
There are no checks to verify whether the data loaded by the driver are correct.

P6 START SID PROCESSES

During this first SID phase, the processes required for operation of the program are created. Once the processes have been
run, SID goes on to the next phase.

3-22 MDO1384 FIDIA

P7 START SID COMMUNICATION
During this phase, SID checks the connection and communication with Maint. If the connection is working properly, SID goes
on to the next phase.

P8 SID CONNECTED AND READY

During this phase, the SID input page is displayed on Maint. When the prompt (SID>) is displayed, the CPU displays are
switched off.

3.10.2 CONFIGURATION

Standard configuration of the MFB1 board

3.10.3 INHIBITION OF FAULT INPUTS

Each fault input, for a particular counting channel, may be enabled/disabled by means of a jumper:
W6 channel 0
W11 channel 1
W16 channel 2

If the jumper is inserted in position E, the respective input UAS* is enabled. On the contrary, if the jumper is in position D, the
relevant input is not connected and the corresponding fault bit will be read always at zero. This is useful when the transducer
connected does not provide the fault signal.

3.10.4 UNIPOLAR/DIFFERENTIAL SELECTION

Each input signal, for a particular counting channel, can be either the differential or unipolar type. Selection is by means of
jumpers, there being as many jumpers as there are signals. For each signal: when the jumper is inserted, this means the input
is unipolar; when the jumper is not inserted, the input is differential. The handwheel is a typical example in which the transducer
outputs are unipolar.
The table below shows the corresponding signals, channels and jumpers.

SIGNAL CH #0 CH #1 CH #2
UA1* counting W2 W7 W12
UA2* 90° counting W3 W8 W13
UA0* index W4 W9 W14
UAS* fault W5 W10 W15

3.10.5 ANALOG INPUTS/OUTPUTS (AEX ADD-ON)

Each output is buffered and has a compensation circuit for piloting high capacitive loads and protecting the output from GND
short circuits. By adding an AEX1 analog expansion board, two additional analog outputs and two differential analog inputs,
with the same characteristics as those in the standard kit, are available.
The additional inputs are identified as ±VIN4, ±VIN5, the outputs as VOUT2, VOUT3.
Instead, by adding an AEX2 analog expansion board , four additional analog outputs (no analog inputs) with the same
characteristics as those in the standard kit, are available.

3.10.6 DIGITAL INPUTS/OUTPUTS (DEX ADD-ON)

The MFB1 board can interface up to 64 digital inputs and 64 outputs. The signals leave the board at a TTL logic level and can
be boosted to 24V using a DEX1 board. The signals are distributed through 4 connectors, each of which can interface 16 digital
inputs and 16 outputs.
The user can have up to a maximum of 4 connectors with the signals divided as follows:
MFB digital 33L: 16 inputs + 16 outputs (0÷15)
MFB digital 33H: 16 inputs + 16 outputs (16÷31)
MFB digital 34L: 16 inputs + 16 outputs (0÷15)
MFB digital 34H: 16 inputs + 16 outputs (16÷31)

WARNING!
In order to avoid damaging both on DEX or DRTX(W) boards the 24Vdc power supply must be present before any input signal
goes “high”.

Digital I/O at TTL logic level

These coincide with the I/O bits of the MFB1 board.
There are also terminals for powering an external circuit on the connectors. In the C standard configuration, the first 32 bits
(connectors 33L and 33H) are used for interfacing the pushbutton panel.

Additional 32 bits for signals located on connectors 34L and 34H may ONLY be of this type, through a DEX1 board (for C2
systems also connectors 33L and 33H). The DEX1 is an optional board for the MFB1 board digital I/O. It can interface up to 16
digital inputs and 16 outputs. These signals, on the MFB1, are at a TTL logic level. The board converts the outputs from TTL to
a 0..24V logic level and vice versa for the inputs. The high current digital outputs can drive lamps, relays, etc. The DEX1 is
physically located inside the connector panel of the C system.

3.10.7 INSTALLATION

DEX1 board

Installation consists of the following phases:

Attachment to the system chassis using connector JP1 as a support.
Connection to the digital Inputs/Outputs of the MFB1 board. Connection is by means of a 40-way flat cable (DEX1 side:
connector JP2; MFB1 side: connector JP3, JP4, JP5 or JP6).

Jumpers are not configured during installation.

3.10.8 FBUS, SERIAL LINE FOR DIGITAL I/O

The FBUS is a high speed (375 Kbits/s) serial bus for the digital I/O that interfaces the C system with the DRTX and DRTXW
modules.
It significantly simplifies the connection of the digital I/O signals between the electrical cabinet and the numerical control.
The FBUS uses a FIDIA standard similar to the RS485, but it is de-coupled through the isolation transformer.
The maximum distance is reached and guaranteed only when the cable has the following characteristics:
twisted duplex cable (see following figure)
double shield with copper stranded wire, aluminum leaf and wire for connection
characteristic impedance of 120 Ω
capacity 50 nF/Km

The MFB signal is not reconditioned between one device and another, therefore what counts is the sum of the lengths of the
individual cables used.
In order to increase noise immunity, it is important that the cable is not interrupted between two devices.
Furthermore, this cable must not run close to power cables.

Example of FBUS communication cable sketch

FIDIA supplies a cable coded as MCG110; it consists of 3 twisted pairs where each pair has its own "common" wire coloured in
black with a stripe coloured like its "signal" wire.

Serial line connection

The following figure illustrates the connection between the MFB1 board and the DRTX/DRTXW boards. A jumper must be
made between pins 6 and 7 on the MFB1 connector in order to terminate the line.

The line must also be terminated at the other end of the connection by jumpering pins 22 and 23 of the last
DRTX/DRTXW module (see next figure).

On C2 systems, the FBUS line also connects the CNC to the PCX1 boards. If the last board in the line is a PCX1, termination
must be implemented on the board as described in the relevant paragraph.

FIDIA MDO1384 3-33

Serial line connection

If there are more than one DRTX/DRTXW connected to the FBUS line, each board must have a different address. The address
is determined on the basis of the jumpers between the ADX0...7 pins and the GND pins of the serial line connector (see tables
below).

3.12.3 INHIBITION OF FAULT INPUTS

Each fault input, for a particular counting channel, may be enabled/disabled by means of a jumper:
W5 channel 0
W10 channel 1
W15 channel 2
W20 channel 3
W25 channel 4
W30 channel 5

If the jumper is inserted in position E, the respective input UAS* is enabled. On the contrary, if the jumper is in position D, the
relevant input is not connected and the corresponding fault bit will be read always at zero. This is useful when the transducer
connected does not provide the fault signal.

FIDIA MDO1384 3-37

3.12.4 UNIPOLAR/DIFFERENTIAL SELECTION
Each input signal, for a particular counting channel, can be either the differential or unipolar type. Selection is by means of
jumpers, there being as many jumpers as there are signals. For each signal: when the jumper is inserted, this means the input
is unipolar; when the jumper is not inserted, the input is differential.
The table below shows the corresponding signals, channels and jumpers.

3.16 PCX1 - SERIALIZED PUSHBUTTON BOARD
The PCX1 board is used only on C2/C10/C20 versions. It is located on the operator console; it manages digital, counting and
analog I/O signals: standard "C" pushbutton panel, PSC1, HPX, HPJ .
24V digital I/O signals are NOT managed.
The board is connected via FBUS (see relevant paragraph MFB1 ) to the interface rack.
Two console system configurations carry two PCX1 boards. The I/O connectors are accessible from the rear of the console;
see relevant figure in Section C2/C10/C20 – CONNECTOR LAYOUTS

Relevant arguments:
• PCX1 technical characteristics
• PCX1 configuration

3.17 PCX1 TECHNICAL CHARACTERISTICS

• Interface for incremental digital position transducers, consisting of 2 counting channels with 2 inputs for each channel; it
may be configured in differential or unipolar mode; the inputs are TTL compatible, available on XC1 and XC2 connectors,
suitable for interface handwheel encoders, typically for PSC1 options.
• 8 unipolar analog inputs with range of 0-5V, resolution of 8-bits (LSB=19.6mV); they are used for interface potentiometers,
two of which are those of the standard pushbutton panel (connected internally); the remaining six channels are available for

The RT* signals are used only when a serialized portable pushbutton panel (HPX or HPJ options) is to be connected directly to
the console, via the PCX1 board, in order to simplify the wiring (see details before).
In general, the PCX1 board is wired at the end of the FBUS, therefore terminating the bus.
The following figure shows an example of linking the FBUS line, relevant to a single Console C2/C10/C20 system

Wiring example of PCX1 on FBUS

3.17.3 LINK TO FBUS SERIAL LINE FOR TWIN CONSOLE SYSTEMS

On a twin console system, each with its PCX1 board, the wiring may be of two kinds:
• The two consoles are located at both ends of the FBUS line, leaving the MFB (the FBUS portion of it) in between; the FBUS
line terminations are made on the PCX1 boards (standard setting) and not on the FBX (non-standard setting). This
solution, generally, saves cable.

Wiring example #1 of PCX1 on FBUS on twin console systems

• The FBUS line terminations are on the MFB1 and console #2, therefore the jumper W2 on PCX1 on console #1 shall be
removed (refer to HW installation manual for details).

Wiring example #2 of PCX1 on FBUS on twin console systerms

3.17.4 LINK TO PORTABLE HAND PENDANT

Descriptions above are valid if the configuration:
• does not include portable pushbutton panels (HPX and HPJ units)
• includes portable pushbutton panels directly connected to the interface rack within the electrical cabinet.

On C2/C10/C20 configurations it is possible to link the portable pushbutton panels to the console via a connector located on the
chassy (at customer care): this solution simplifies the wiring (see details on Section HAND PENDANT ).

3.18 PCX1 CONFIGURATION

Standard configuration of the PCX1 board

3.18.1 FBUS LINE TERMINATION

The FBUS serial line termination resistance is inserted by means of jumper W2. As with all other boards that can be connected
to this type of bus, the jumper must be inserted if the PCX1 board is positioned at one of the ends of the line.

3-48 MDO1384 FIDIA

To avoid malfunctioning, great care must be taken when positioning this jumper. In the standard configuration, the jumper is
inserted (termination active).

3.18.2 UNIPOLAR/DIFFERENTIAL SELECTION

Each input signal for a counting channel can be of the differential or unipolar type.
Selection is by means of jumpers; there are as many jumpers as there are signals. For each signal: an inserted jumper means
a unipolar input, a jumper that is not inserted means a differential input.
The handwheel is a typical case in which the transducer outputs are unipolar.
Jumpers W4 and W5 refer to counting channel #1, while jumpers W6 and W7 refer to channel #2.

3.18.3 BOARD ADDRESS

The address of the PCX1 board is selected by means of jumper W9. Allowed addresses are:
#1 corresponds to the jumper in position 0
#2 corresponds to the jumper in position 1

The PCX1 address must correspond to the address of the console in which it is housed (see the paragraph CONFIGURATION
OF THE CONSOLE under the section on the KMVM1-KMVS1 boards).
If there is only one console managed as console #1, the PCX1 board must be set to address #1.
If there are two consoles, the PCX1 board housed in console #1 must have the address #1; while the board housed in console
#2 must have the address #2.

3.18.4 DIAGNOSTICS
A DL1 led is present on the board (not visible from the exterior). If the LED is illuminated, this means the loading of data at
power on has not been successfully completed and the board might not function correctly.

3.19 KMVM1 - KMVS1 KEYBOARD MOUSE AND VGA INTERFACE

BOARDS
The KMVM1 and KMVS1 interface boards are for C2/C10/C20 systems only. They enable a personal computer with one or two
operator positions (console) to be commanded at a distance of up to 50 metres from the PC.

These boards provide for the transmission of VGA signals, as well as keyboard and mouse transmission. In systems with two
consoles, it is possible to switch consoles using a combination of keys or a special soft key. In systems with a console, a
terminal connector is provided for the channel that is not used. This is inserted during manufacturing and should not be
removed. KMVM1 is the master board inserted in the rack; in the rack it is connected to the keyboard and mouse ports and to
the VGA board of the PC. In addition the board has two connectors for communication with as many KMVS1 boards. KMVS1 is
the slave board mounted in each console; within the console it is connected to the keyboard, mouse and LCD monitor. In
addition the board has one connector for communication with the KMVM1 board.

respective ground pins according to the cable length (see below).
The /CONN pin is used by the board to determine the presence of the cable. It must always be connected via a jumper to pin
12; otherwise there is no data transmission between the master and slave boards.

JKM1 - KEYBOARD/MOUSE CONNECTOR

This connector (D type, 9-pin, female) is connected to the PC keyboard and mouse ports.

JV1 - SVGA INPUT CONNECTOR

This is the input connector for the VGA signals, connected to the video board. It is a high density, 15-pin male connector; its
pin-out follows the VGA standard.

3.19.3 COMPENSATION OF CABLE LENGTH

It is possible to compensate for the length of the connection cable between the KMVM1 and KMVS1 boards by soldering the
jumpers directly onto connector XKMV1/2 of the KMVM1 board.
These jumpers are used to compensate for stray capacitance of the connection cable to the slave board.
This capacitance influences the RGB signals and can lead to poor quality of the image displayed.
The table below shows the jumpers to be soldered depending on the cable length.

COMP2 = Pins 9-22
COMP3 = Pins 10-23

N.B. – The cable length indicated in the table is approximate. Image quality also depends on the LCD monitor setting.

3.19.4 CONFIGURATION OF THE CONSOLE

The console address is not selected by means of jumpers; the address simply depends on the connector selected on the
KMVM1 board. The console connected to connector XKMV1 of the KMVM1 board is automatically assumed to be console #1,
while the console connected to connector XKMV2 is assumed to be #2. In the case of one console only, it is recommended for
the sake of simplicity that it be connected to connector XKMV1 of the master board so that it will be considered console #1.

Only one console at a time is active; the operator may switch the commands easily between them, provided that they are both
fully connected and working.
When powering on the iPC, at least one of them must be working, in order to avoid error messages (for example, missing
detection of keyboard or mouse).
The switch between consoles is possible in two ways:
• by pressing in sequence (but keeping all pressed) the left "Control" , the left "Shift" and the "." keys;
• by activating the proper Soft-key.

The configuration of the console shall be done according to the following rules:
• if both consoles carry a PSC1 service panel, both PSC1 MUST have the same signal configuration;
• if one portable pushbutton panel option is present, but it has to be used on both consoles, both wiring I/O configuration
MUST be the same; mind that un/plugging the portable panels requires switching off/on the machine;
• both operator consoles must have the same dimensions (12”, 15”, 18”).

For details concerning the link between console and interface rack, refer to paragraphs on PCX1 and KMVM/S boards.
The jumper W9 on the PCX1 board in the 2nd console must be set accordingly (it is normally factory configured).

4 WIRING MODULE OPTIONS
4.1 WIRING OPTIONS GENERAL DESCRIPTION
The Wiring Module Options are interface modules which make the wiring between the FIDIA system and the Machine tool
simpler and faster.
They take up very little space and have electrical features that can be used to solve some electrical wiring problems.
Most modules are designed so to receive wires from external devices and carry them in groups via a flat cable to FIDIA C
boards.
Digital I/O modules gather and exchange 32 signals at a time on a FBUS line.
The interface modules are as follows:
• ARTW interface board to DAB board.
• ATRW interface board to MFB board
• BICW1 laser device interfacing board
• DCBW interface board to DAB - MFB boards.
• DCBYW connecting module for digital transducers and DAB board
• DEXW interface board to DEX board
• DRTW interface board to DRTX board
• DRTX serialized digital I/O board
• DRTXW serialized digital I/O board
• EXTW universal board for any CNC board

For information on flat cable features, see the "Flat Cable Specifications " section in this manual.
Serialized digital I/O cable features are described in the section dedicated to MFB-FBUS.

4.2 MODULE ASSEMBLY

Wiring Modules are mounted in the electrical cabinet by means of DIN rails. These may be:
• TS 32 DIN EN 50035
• TS 35 DIN EN 50022

The DRTX serialized modules must be mounted on the machine tool using 2 mounting screws.
The mechanical specifications of the DIN rails are shown in the following diagrams.

DIN rails type: TS 32.

FIDIA MDO1384 4-1

DIN rails type: TS 35.

4.3 DRTW OPTION

The DRTW board interfaces the DRTX module with the machine tool. It is mounted on a special modular plastic support that is
widely used for installing the various components of electrical cabinets. The board can therefore be installed easily in the same
way as the other electrical cabinet components.
The DRTW board must be mounted in such a way as to allow access to the interface connector and to the terminal strips.
The technical features are as follows:
• Female "D" type, 37-way input connector with a pin-out identical to that of the DRTX board.
• Output terminal strip allowing for direct connection to the digital I/O signals, DRT00 .. DRT31.
• Some LEDs for the I/O signals, ENOUT signal and the VCCH power supply.
• 8 digital power outputs, connection to one contact power relays with main current on the contact of 10A @250V.

The three NC, C, NO terminals are available on the terminal strip.

The relays used on this board are manufactured in accordance with the IEC 255-1-00 International Standard and comply with
the insulation categories of the VDE0110 Standards. The contact socket is made of resin and is therefore particularly resistant
to leakage currents.

Connection of the DRTW board to the machine tool is via two rows of printed circuit terminals soldered onto the same board.
The Following figure shows the layout of the terminals on the board and their function. In order to facilitate the connection of
several DRTW boards inside the electrical cabinet, the terminals reserved for the power supply and for the ENOUT signal have
been doubled in number. The boards can therefore be supplied and enabled in cascade.
If you do not require the ENOUT signal to be managed, simply make a jumper to VCCH on terminal M9.

 Mechanical dimensions of the DCBYW

The DCBYW module consists of a base card called the DCBYW1 on which the electronic digitizing and interpolation cards,
called DCBYWA1, DCBYWC1 and DCBYWD1, are installed. The connectors for connecting the encoders and the DAB
counting electronics are also provided along with the cards.
There are three types of digitizing and interpolation electronics which can be connected to the module: DCBYWA1, DCBYWC1
and DCBYWD1.
The DCBYWA1 card is used when the interfacing of devices do not require interpolation electronics (e.g. handwheels and
rotating transducers with built-in electronics).
The DCBYWC1 and DCBYWD1 interpolation cards are used for all linear, rotating or angular encoders that have sinusoidal
signal outputs. They can interpolate encoder signals by dividing them by 5 or by 25, as well as interface the index and fault
(encoder out of order) signals.
The DCBYW, as a result of the special plastic module on which it is installed, can be easily secured inside electrical cabinets on
the DIN EN 50035 and DIN EN 50022 guides.
The maximum displacement speed of a linear transducer or rotation of a rotating transducer depends on the maximum
mechanical speed and on the maximum electrical speed; the last one depends on the maximum input frequency of the
DCBYW.
The maximum displacement speed is given by the following relation:
-2
V[m/min]=p x f x 6 x 10
where:
p = division pitch of the transducer in µm
f = maximum input frequency of the card in KHz (25 KHz)

For example, in the case of an optical line with a resolution pitch equal to 20 microns, the maximum displacement speed is
equal to:
-2
Vmax=20 x 25 x 6 x 10 = 30 m/min

In the case of rotating transducers, the maximum rotating speed is given by the following relation:
4
N[rpm]=(f/z) x 6 x 10
where:
f = maximum input frequency of the card in KHz (25 KHz)
z = number of lines of the rotating transducer

For example, in the case of an angular transducer with 18,000 divisions, the maximum rotation speed is equal to:
4
Nmax=(25/18,000) x 6 x 10 = 83 rpm

FIDIA MDO1384 4-13

4.8.3 DCBYWC1 AND DCBYWD1 - X25 INTERPOLATION CARDS
The DCBYWC1 board interfaces a current signal, while the DCBYWD1 board interface a voltage signal.
These boards are X5 or X25 interpolation cards.
Signals originating from the encoder are first amplified and then converted by two 8-bit A/D converters. The output of the
converters are used for addressing an EPROM containing a table that is used for retrieving the immediate position of the
encoder.
An 8-bit word containing the position of the encoder is furnished upon exiting the EPROM, where X0 and X1 (bits 6 and 7)
represent the quadrant and bits Y0-Y2 and Z0-Z2 represent the counters from 0 to 4 that divide the quadrant into 25 parts.
Subsequently, this data is processed by a control logic (LP101) to generate the card output signals.

4.8.4 CONNECTING THE DCBYW

The DCBYW is equipped with a 37 way “D” type female connector for connecting the counting card (JP1) and with three
connectors for connecting the encoders (J1, J2 and J3).
A connector available on the PCB allows for additional power source between the interface counting board and the wiring
module. For details see Section DIGITAL POSITION TRANSDUCER SPECIFICATIONS .

The measuring pitches which can be obtained with certain types of linear and angular position transducers are illustrated in the
relevant table of the preceding Section.

4.8.6 CONFIGURATION
DCBYWA1 BOARD - X1 INTERPOLATION
This board is used for interfacing devices that already have a square signal in output and consequently do not require
interpolation electronics (e.g. handwheels and rotary transducers with built-in electronics).

INHIBITION OF FAULT SIGNAL

If the device connected to it does not have a fault signal (e.g. handwheel), the fault signal can be disabled by inserting the W1
and W2 jumpers, or by jumping the 2-3 pins and the 1-12 pins on the encoder connection cable connector (J1, J2 o J3).

SELECTING X5/X25 INTERPOLATOR
The interpolation mode of the board is selected based on the resolution to be obtained:
X5 W2 jumper inserted in the '0' position
X25 W2 jumper inserted int the '1' position

COUNTING INVERSION
By inserting jumper W3 in position 1, the UA1 signal is inverted resulting in inversion of the counting (changes the direction of
the movement detected by the transducer). Normally this jumper is in position 0 (counting not inverted).In normal condition
remaining jumpers must be kept in the standard configuration shown in the figure.

4-26 MDO1384 FIDIA
5 BASIC SYSTEM
5.1 BASIC SYSTEM GENERAL DESCRIPTION
The Fidia CNC is based on a Pentium (TM) chip based mother board and includes, in addition to all interface boards, a 3"1/2
floppy drive which may be remoted (see Para REMOTING A FLOPPY DISK DRIVE ), a CD-ROM drive, a hard disk and an
ethernet board; the operating system is configured accordingly.
The CNC is customized, based on the machine, with one of the following main axis options:
• /DA analog drives with digital encoder/scale position feedback
• /SS Siemens digital drives
• /II Indramat digital drives

The FIDIA numerical control system is linked to the machine tool by means of cables and connectors wired by the customer.
The basic system is configured to allow for the following functions:
• Digital axis counting;
• Axis and spindle command signals (end of travel, speed, locking axis, etc.);
• Feedrate and spindle override;
• Miscellaneous signals (tool change, lamp test, M T S BCD codes etc.).

A C_GEN program, running on PC, provides a standard I/O configuration, which may be changed upon customer's suggestion.
For digital I/O signals, the connection is usually made on DRTX or DRTXW boards, serially linked to the MFB board; a number
of signals is also available, depending upon machine configuration, to be linked to the MFB board, through the DEX1 board, on
the MDI panel itself (see rear view at chapter 1. for details).
On C1 systems, the digital I/O signals for the pushbutton panels are connected to the MFB board via the MFB DIGITAL
connectors. On C2/C10/C20 systems, the pushbutton panel signals (digital I/O, analog inputs, counting signals) are connected
to the PCX1 board which communicates with the CNC via the FBUS line. For analog output to drives and position feedback,
though you may choose between using the DAB board or the MFB board, a homogeneous I/O is suggested for all axis.

Important
It is necessary that the axis/spindle driver gain shall be tuned, in order to run at the maximum speed with ±9Vdc, even though
the analog output voltage reaches higher values.

For digital drives (either Indramat or Siemens) both the output and the position feedback are managed by the drives.
In addition to the machine tool interface connectors, there is also a socket available for an Ethernet network connection on the
back panel of the numerical control.
There are two serial ports, a parallel port and an IDE port for connecting a plug-and-play backup unit compatible with this
protocol.
FIDIA does not service parts or programs installed by the user on the PC.

5.2 AXIS MANAGEMENT

For digital drive management please refer to digital drive documentation (Siemens or Indramat).
The following tables refer to analog drives for axes whose position is detected by digital position transducers. These tables
apply to additional (continuous interpolating), alternate-interpolating (EA10/C), auxiliary, gantry, synchronous and tandem axes.
An additional or alternate-interpolating axis is managed in the same way as a standard X, Y, Z axis.
An auxiliary axis may have different type of drives such as:
• analog drive
• Siemens digital drive
• Indramat digital drive

An auxiliary axis requires the generation of a specific software to be integrated on the numerical control (i.e. automatic tool
change). If the integration must be designed by FIDIA, this software will be evaluated from the technical point of view and then
quoted ( on a case by case basis ) according to detailed operating specifications.

5.2.1 GANTRY AXIS OPTIONS

A gantry axis is used for the management of gantry machines which usually have problems with parallel movement. In fact,
these particular axes are driven by two motors which frequently do not run completely in synchronism. The gantry option is
used to control the movement of these motors in order to ensure the correct movement of the gantry axis. The CNC, controlling
the gantry axis, manages the two motors as two different axes. After appointing a Master axis and a Slave axis, the N.C.
checks the positions of the two axes and calculates their difference. The Slave axis is then compared with the Master axis. In
this way, parallel movement of the gantry is ensured.

FIDIA MDO1384 5-1

The CNC software gives a theoretical position which, after being amplified (KW* gain), enters a motor management loop. In this
loop a tachometer generator "T" is used for motor control, while the position transducer "R" will bring back in input the axis
position that is to be compared with the theoretical position of the N.C. This operation is valid for both the Master and Slave
axes and is the normal management of an axis. The responses of two position transducers "R" are compared and cause a
position error which will be transmitted in input to the Slave axis loop. This is then used to correct the position of the Slave axis
so that it is the same as the Master axis.
The Gantry axis can be mounted on the main X, Y and Z axes or on the additional axes A (4th axis), B (5th axis) and C (6th
axis).

5.2.2 TANDEM AND ANTI-BACKLASH OPTIONS

Both options are available with digital axis drivers only.
They manage an axis moved by motors mounted on the same screw.
They are not to be confused with gantry axes, where each motor drives its own screw, one on each side of the table/column.
Since the motors are mechanically tied up together the speed will be always the same.
Gantry axes, as well as interpolated axes, may be moved by tandem motors; in such case, each screw is driven by more than
one motor.
Each motor shall be managed by its own digital drive.
The option does not require any additional Fidia hardware; the I/O CNC signals managing the axis depend on the axis type
(main, interpolated, gantry), therefore they are described in the relevant chapters.
The anti-backlash option works similarly to the tandem option with two motors on the same screw but the motors work in
opposition, in order to keep the screw in tension and avoid the backlash when reversing the movement direction.

5.2.3 SYNCHRONOUS AXIS OPTION

The option allows for the connection of synchronous milling axes; it is available for digital or analog drives.
A synchronous milling axis repeats the exact movement of the main axis with which it is synchronized (LINKED).
For the axis synchronization logic are available, in addition to those signals used for managing a main or an interpolated axis
the signals :

IDPLK* Digital input for LINK/UNLINKing the axes (* = X, Y, Z, A, &ldots;)

UDLK* Digital output for LINK/UNLINKing lamp; “1” = LINK ACTIVE
IDPAU Digital input for LINK/UNLINKing the axes (* = U, V, W, D,E, F)
UDLAU Digital output for LINK/UNLINKing lamp; “1” = LINK ACTIVE

The pushbutton panel, instead of labels X, Y, Z, 4, A, .. should have XT, YT, ZT, .., in corrispondence to the main (tracer) axis
and should include a LINK/UNLINK button and the syncronous axis button XM, YM, ZM, &ldots;
Following is reported an example of pushbutton panel for 3 axis machine with a synchronous axis on the Z coordinate.

5.2.4 VIRTUAL AXIS

A virtual axis is simulated in order to allow retract movements along the spindle axis; the JOG movements are allowed by
selecting:
• an additional INPUT signal, named IDPA6 (5-axis version) or IDPA7 (6-axis version), which should be included at customer
care in an additional pushbutton panel, or swapped to an unused button of the set of the main push-button panel;
• the relevant OUTPUT (lamp) signal, named UDLA6 (5-axis version) or UDLA7 (6-axis version).

If no proper hardware is added to the standard push button panel, the movement may be produced by entering MDI blocks (see
User Help-on-line for details).

5-2 MDO1384 FIDIA

5.2.5 MULTIPLE AXES
The "multiple axis" option, commercial code MX, refer to "a sort of" virtual axis mixed with characteristics of synchronous axes.
A multiple axis is an axis which may be linked to its relevant "master", it has no JOG buttons, it follows its "master" if
programmed.
All multiple axes referred to the same "master" axis must be identical as far as dimensions, position transducer resolution,
dynamic features and so on.
A number of maximum 6 axes can be managed as multiple.
This option allows to manage machines for multiple work-piece machining.
Typically, they are bridge machines with more than one column, where each column is loaded with a head carrying the tool.
In the following documentation, master axis is intended as the axis who is common to all the multiple and doesn't exist
physically.
In the parameters and in the signal coding, this axis is referred as XM YM ZM etc, while multiple axis are referred as XH,XI,
YJ,AK etc., where the letter H indicates the first multiple, I the second and so on.

5.2.6 HARDWARE BOARD REQUIREMENTS

The maximum number of boards available depends on the system configuration and will be determined for each requirement.
In the following three tables the character * stands for axis code and # stands for the master of multiple axis code, where:.
X, Y, Z main axes
#H, #I, #J, #K, #L, #M multiple axes

 TABLE 3 - DIGITAL I/O FOR AXIS MANAGEMENT
SIGNAL DESCRIPTION
UDSA* Axis selected Digital output. It may be used to enable the servo unit or unlocking brakes (see "Basic
System")

IDA*P Axis ready digital input. It returns a confirmation that the axis has been selected. It has to go "high"
within a given "T" period of waiting time which can be modified during installation. After this delay, the
CNC will drop into an emergency status; if not used, please link to UDSA*.
This signal is not used in case of digital drives.

IDTM* Axis mounted digital input. At "low" level the CNC will ignore the axis as far as emergencies,
movement, and so on. At "high" level the CNC is enabled to read axis position feedback.
This signal is not used on Gantry axis (X1 Y1 Z1 A1 B1 C1).

IDRBL* Axis unlocked digital input. Going to "low" level it will cause UDSA* to go "low" itself therefore releasing
the axis from the position loop. The axis may now be moved by the external logic without an
emergency message. The movement is detected and displayed by the CNC.
This signal is not used on Gantry axis (X1 Y1 Z1 A1 B1 C1).

IDFP* Positive end-of-travel limit digital input. When the signal goes "low", the axis is in an OFF LIMIT
position.

IDFN* Negative end-of-travel limit digital input. When the signal goes "low", the axis is in an OFF LIMIT
position.

IDMZ* Home micro switch digital input. This signal comes from a micro switch mounted on the machine tool
and is relevant only during the ZERO PROCEDURE (see digital/analog counting paragraphs).

WARNING: The IDMZ* signal is not used for CODED ZEROES. For additional information see the
Software Installation Manual.

N.B. - Signals are enabled for slave multiple axes, NOT for master multiple axes

TABLE 4 - MULTIPLE AXIS AUXILIARY SIGNAL MANAGEMENT

SIGNAL DESCRIPTION
ID*MI mirror request; only for multiple axis!
when set, the CNC reverses the Output and looks for a "mirror" position;
ID*ON enable request; only for multiple axis!
the falling edge toggles the axis status (if machine status allows for such change) from enable to
disable or vice-versa
UD*ON axis status; only for multiple axis!
it may be used by external PLC; "low"= axis disabled ;"high"= axis enabled
IDLKC$ $=H or I or ...... M "column"; only for multiple axis!
the falling edge toggles all column axes status(if machine status allows for such change)

General Note about the axis command signals:

Signals are enabled for slave multiple axes, NOT for master multiple axes
The behaviour of the signals UDSA* (axis selection), IDA*P (axis ready) and +UAV* (axis speed command) is shown in the
following diagram.
The sequence for enabling the axis is the following:
NC enabling (M11) function => UDSA* "high" => IDA*P "high" and UAV* reference signal in output

The sequence for disabling the axis is the following:

NC disabling (M10) function => UDSA* "low" => IDA*P "low" and +UAV* to 0V

The M10 and M11 instructions work simultaneously on all axes.

The M12 instruction on the other hand allows only one axis to be locked, keeping the others "alive".

 Timing diagram for axis selection.

Without mechanical locking, the UDSA* signal stays "high" (+24V) if UDCMA=1; it stays "low" if UDCMA= 0.

5.3 SPINDLE MANAGEMENT

C class manages spindles which may have a digital position feedback.
Table 4 shows general signals for all spindle types (check note on UDAMP signal).
Table 5 shows general signals for all spindle types relevant to gear change logic.
Table 6 shows additional signals necessary when dealing with position controlled spindles.

TABLE 4 - DIGITAL I/O FOR SPINDLE MANAGEMENT – GENERAL SIGNALS

SIGNAL DESCRIPTION
UDSMO Digital output for commanding CW spindle rotation. It corresponds to the M03 programming function. This
signal is reset by the M05 instruction.
UDSMA Digital output for commanding CCW spindle rotation. It corresponds to the M04 programming function. This
signal is reset by the M05 instruction. If two separate signals are not used for M03 and M04, please connect
UDSMO and UDSMA together.
IDRTM Digital input for confirming spindle rotation. It confirms that the spindle started rotating. After a command to
rotate, IDRTM has to go "high" within a given pause time T (which may also be adjusted during installation).
After this delay, the CNC will drop into an emergency status; if not used, please link to UDSMO.
IDIRM Digital input for spindle rotation reversal. With this signal the programmed spindle rotation may be reversed
without modifying the program. If it is not used, leave it floating.
UDAMP Digital output for spindle positioning request. Following an M19 programming function, the CNC executes an
M05 programming function, sets "high" the UDAMP signal and waits for the spindle positioned response
(IDMAP signal).
NOTE: This signal is not used when dealing with D.C. spindles with position feedback
IDMAP Digital input for spindle positioned response. There is no time out.

5.4 OVERTEMPERATURE ALARM LOGIC

Each numerical control has a built in temperature sensor that can activate a buzzer (e.g. when iPC is mounted inside a Fidia
PF14 cabinet).
The characteristics of the buzzer (or a logic that drives an audio or visual equipment) are as follows:
5V 15 mA

The connection is located on the rear of the C1 chassis (see INTERFACING CONNECTOR LAYOUTS ) or on the C2/C10/C20
Interface rack. Once the temperature is reached, the contact closes and a warning message is displayed.

Overtemperature alarm logic wiring

On C1 versions the input signal IDAST is internally connected to active-low keyboard logic.
On C2/C10/C20 there are three possible solutions, at customer care:
• connect the sensor contact to the 24V input of a DEX1 or DRTX(W) board;
• connect the sensor contact to the CPU, between IN*- and GND terminals (remember that IN*+ must be linked to PD*); in
this case the buzzer is not applicable.

Following is a reference table for all configurations.

pin C1.f C2/C10/C20: DEX, DRTX(W) C2/C10/C20: CPU

1 +5V GND reserved
2 GND +24V GND\CPU
3 IDAST IDAST IDAST
4 BZ+ BZ- reserved
5 BZ- BZ+ reserved

Note: On the C2/C10/C20 systems, alternatively to the sensor used within the interface rack, an additional sensor (at customer
care) may be connected to the 4-way XAST terminal block on the rear of the console the NO contact terminals may be tied to
XAST 2 and 4 terminals.

5.5 UPS UNINTERRUPTIBLE POWER SUPPLY

The system memory, as well as the CNC memory is volatile, without support of battery backup.
A power failure lasting about ten milliseconds may cause the memory clearing, with consequent loss of data, and even a
damage on storage devices.
While machining path data are retained on mass storage devices, temporary data, such as updated Tool Tables, procedure
Registers, and so on, will require hard and careful work to resume the job at the same conditions it stopped.

FIDIA MDO1384 5-7

These situations may be unpredictable, but, in particular industrial areas, where the mains do not supply sufficiently stable
voltages, they occur several times a week causing undesirable waste of time. In order to avoid such effects, U.P.S. are used to,
at least, allow the computers some time to save the data to disk. There is a large number of UPS, ranging in power and
"operating modes". Fidia interfaces a device with Stand by operation: it means that the iPC is linked to the mains line; the UPS,
in parallel, detects any signal discontinuity and it takes over the control and allows 5' for the power down procedures to be
completed. In order to avoid continuous discharging of backup batteries, due to daily overnight system power-off, make sure
that the device has an input signal for disconnecting the output, commanded by the main switch.
The automatic power down procedures are enabled by means of a relay contact, the NC contact should be linked to a Digital
Input channel (best if on the CPU board, in order to avoid voltage uncertainty if tied to unstable 24V source).
The signal IDPWD (normally "high") may be activated by the CM10/024 option in the C_GEN.

5.6 PUSHBUTTON SIGNALS

The signals in this area are generally determined automatically by the C_GEN utility in a fix position. It is though allowed
customising this area, minding that wiring may not be altered. Some signals, for instance those relevant to the PLP, are
defined even if the option is not active in the CNC. You may then like to replace them with your own functions, provided that
you replace your own symbol in place of the standard symbol underneath the button lens you are NOT going to use.
Following is an example of the standard C Class push-button panel.

Following is the example list of standard signals used to interface the FIDIA Pushbutton Panel.

5.7 UTILITY SIGNALS
SIGNAL DESCRIPTION
UDCIR Digital output for coolant application (programming function M08). Reset by the M09 instruction.
UDCSC This signal is used to enable and disable the supply of spray coolant. When the M07 instruction is
programmed, the FIDIA CNC sets this signal "high" to allow an external logic to start lubrication. When the
M09 instruction is programmed, the signal is reset to stop lubrication.
IDHLD Digital input for the automatic stopping of the axes when there is insufficient lubrication or various
emergency conditions from which the machine tool can recover. When any one of these conditions occurs,
the signal (normally "high") goes "low", commanding the FIDIA CNC to stop the axes and display a
Warning message.
UDCNON Digital output of CNC in block execution. Goes to 1 when the CNC is executing a program or automatic
copying. When axis movement is in JOG or STEP, it goes "low".
UDLPLP Digital output of CNC in automatic copying. This is "high" during PLP scanning; "low" otherwise. It may be
used in order to reduce integral gain of the drives in PLP mode in order to obtain smoother surfaces during
direct copying of planes parallel to the axes.
UDG00 Digital output for rapid positioning. Corresponds to the G00 instruction.
IDPFC Digital input for pre off limit end-of-travel. This digital input is normally at "low" level. When an axis is driven
over the microswitch, IDPFC goes to "high" and the speed of the axes is reduced (generally by 50%). All
pre end-of-travel microswitches must normally be of an open type, connected in parallel.
IDPWD Digital input for power down management (with UPS devices).Normally "high", it drops "low"; the CNC
software checks for a continuous "low" for 10s before stopping the machine (if not yet stopped)and starting
the shutdown procedure. The signal is available by selecting CM10/024 option in C_GEN.
UDGNA Digital output for Gantry Not Aligned. Normally "low", it goes "high" when the primary AXVTOLL1 Gantry
tolerance threshold is exceeded; available by selecting CM10/021 option in C_GEN.
IDJM03 Digital inputs for CW/CCW spindle jog management. Normally "low", when set, the signals will command
IDJM04 the spindle to turn at a given rpm value, defined by the SP1JOGS parameter; available by selecting
CM10/022 option in C_GEN.
IDPHWR Digital inputs for "T" pushbutton logic management. Normally "low", when set, the movement through
UDLHWR handwheel is allowed along the real tool axis, with RTCP active. The output signal for a lamp goes "high" to
warn that the logic is active; available by selecting CM10/025 option in C_GEN.
IDPTL Digital input for Lamp Test Pushbutton. Normally "low", when set, the NC sets all these outputs to "on";
available by selecting CM10/015 option in C_GEN.
IDPDFL Digital Inputs/Outputs for changing the analog tracer nominal deflection by means of the handwheel.
UDLDFL Normally "low", when the input goes "high" the output also rises and the handwheel is enabled. After
reaching the desired nominal deflection, press the button once again to set the new value. While operating,
the values relevant to: nominal deflection, the correction and the real deflection are available on the screen
in the PLP pages.

5.8 NIGHT/DAY AND MANUAL/AUTOMATIC

5.8.1 NIGHT AND DAY MODE
It is possible to install a NIGHT/DAY switch, which may be used for shutting the electrical cabinet off, following an NC end-of-
work programming function of an emergency situation.
The contactors of the relay R for the NIGHT/DAY selector may be used to switch the main power supply.
In order to avoid loss of data which may produce malfunctions, run the correct operating system shutdown procedure as
described in the START UP MANUAL.

5-14 MDO1384 FIDIA

5.8.2 MANUAL/AUTOMATIC LOGIC

Manual/automatic Logic

With the FIDIA CNC the customer has a choice of two working modes: MANUAL or AUTOMATIC. When the CNC is in
AUTOMATIC mode, it controls the machine tool. Instead when the CNC is in MANUAL mode, the machine tool is controlled by
the operator or by an external logic. You can switch from MANUAL to AUTOMATIC if you want to run a CNC program, and you
can also switch from AUTOMATIC to MANUAL if you want to stop a CNC program (for example in emergency situations).
To obtain this function the customer must connect a pushbutton panel as in the circuit shown in the previous figure, or as
shown in the relevant Section.

AUTOMATIC MODE
The CNC must give approval to the AUTOMATIC mode by setting "high" the UDCMA output signal. But this output signal will
not be active unless the ENOUT signal is active. In fact the CNC digital outputs are only active if the ENOUT signal (pin 36 of
each digital I/O board) is "high". By pressing the "AUTO" button, the ENOUT signal goes "high". This activates all the CNC
outputs to control the machine tool and remain "high".
It is recommended that the output UDCMA be connected to the ENOUT input of all the other digital I/O boards installed in the
system.
For safety reasons, the outputs of the board including UDCMA must not enable axes or spindle movement. The CNC tests the
ID24C bit (+24V for electrical cabinet). If this bit is at "high", it means that the power supply (+24V) is ready and it is possible to
enable the AUTOMATIC mode.

FIDIA MDO1384 5-15

MANUAL MODE
The control goes to MANUAL mode by disabling the UDCMA signal (CNC command) or when the "MANUAL" pushbutton is
pressed (user command). In these two cases ENOUT goes "low" (0V) disabling all CNC outputs (every output will be set "low").
The "AUTO" and "MANUAL" pushbuttons are optional; when NOT present, to go to AUTOMATIC mode, you must type the
"ENABLE/CNC" command, while to go to MANUAL mode you must type the "RESET/CNC" command.
If you need MANUAL mode (controlled by an electrical cabinet logic), you can remove the ENOUT signal from the board where
the UDCMA signal is located.
If the UDCMA signal is in the memory (according to an AUCOL modification), in order to go to MANUAL mode it is not enough
to remove the ENOUT signal. This is because the UDCMA and ID24A signals can also be linked via software. In this case,
AUCOL has to manage the ID24A signal.
With AUCOL programming, the user can modify the status of outputs when the control is in MANUAL or AUTOMATIC mode.
Generally these outputs must not enable axes or spindle movement, but must control some management signals (lubrication,
lamp, etc.). Usually the ENOUT signals of all boards are connected together. But if you do not wish to manage the ENOUT bit
of a particular board, you can connect the ENOUT bit of this board to +24V directly (FIDIA does so on the pushbutton panel
connectors). Remember that pins Nos. 18, 19, 37 of the board connector are connected to +24V d.c. (VCCH) and pin No. 1 is
connected to 0V (VCCL). The VCCH and VCCL pins of all boards are connected to the cabinet power supply.
If you use two different power supplies (one for input signals and the other for the VCCH of the board), it is important to
remember that when the power supply for input signals is on, the other power supply must also be on. Otherwise the board will
be damaged. It is recommended that the 0V power supply be connected to ground for safety. It can be left floating only if it is
lower than the safety voltage.

5.9 INPUT/OUTPUT BCD OPTIONS

These options consist of a series of digital outputs for 2, 4 or 6 BCD digits. These codes are used for various user functions,
which may be of the following type:
A -> axis or spindle positioners (indexed axes).
S -> spindle selection range.
T -> tool change.
M -> miscellaneous.

They are:
four-digit BCD functions for positioner (indexed axis).
two-digit BCD M functions.
two-digit BCD messages or 200 binary messages
two-or four digit BCD S functions, alternative to the D.C. spindle Options.
two, four or six digit BCD T functions.

IMPORTANT! With these options, the signals must be located in numerical order on each digital input/output board. They must
be assigned in groups of 8 or 16 signals, starting from LSB.

The LSB must be positioned to start at bit 0, 8, 16 or 24 for the 2 digit options, at bit 0 or 16 for 4 digit options and at 0 for the 6

The IDF*E signal has to go to "1" within a given period of waiting time "T", which can be modified during installation. Once this
period has elapsed, the FIDIA control will signal an emergency.

5.10 ADAPTIVE CONTROL

This option allows for adaptive feed control of an axis. The axis feed is reduced automatically by the CNC when carrying out
machining operations for which the spindle uses considerable power. This option can be of two types. The axis feed can be
direct or reverse proportional to the voltage coming from an analog input (IAAC). The voltage value may range from 0V to 10V.

feed.
-IAAC Analog input negative terminal for adaptive control.
SHIAAC Shield for adaptive control.

When this signal is at logic "0", the option is not active and the axis feed is that determined by the position
of the "OVERRIDE FEED" potentiometer. When it is at logic "1", the adaptive control is active.

5.11 THERMAL COMPENSATION
An analog DC input channel may by used for a linear compensation on axis position or tool length due to a change in
temperature or, more generically, to the analog signal provided as IACTn (from 0 to 10 V). The value 0V corresponds to no
correction; a higher voltage corresponds to a correction value that is proportional to the voltage value.
Up to five of such compensations may be managed by the software.

THERMAL COMPENSATION SIGNALS

SIGNAL DESCRIPTION
+IACT* Analog input positive terminal for thermal compensation.
The voltage for this input must be variable in the range 0 to 10V and must come from a suitable
temperature transducer.
-IACT*
Analog input negative terminal for thermal compensation.
SHIACT
Shield for thermal compensation.
* = _, 1, 2 for 1st, 2nd or 3rd thermal compensation

The INPUT CT* parameter (in INIPAR.DEF) defines the channel on which the analog signal arrives.
The correction is calculated by the following expression:
?X = analog input . [(AXTRATE . 10) / 2048] .[(axis position – AXTP0) / ( AXTP1 – AXTP0)]
The parameters are in the SERVICE area (INIPAR.SET) and have the following meaning:
AXTRATE *M defines the correction value in millimetres corresponding to a 1 Volt signal.

The AXTP0 and AXTP1 parameters define the points of reference for correction that is proportional to the axis position:
AXTP0 *M defines the point with nil correction.
AXTP1 *M defines the point with 100% correction.

If constant compensation is desired at all positions of the axis, simply define AXTP1 = AXTP0.

6 TOOL MEASUREMENT
6.1 TM10/MD OPTIONS
This option is used for the automatic management of a tool cycle with a digital measuring device. In this way, the real
measurement of a tool is obtained and then a check can be made to see if the measurement falls within a given tolerance.
With this option, the Tool Setting system is employed for the tool measurement cycle and uses Hard Wired Transmission (for
more details, see the Measuring and Scanning Options section).
A digital instrument, i.e. Renishaw probe, is used for measuring. The Renishaw probes used for the tool setting mode require
the MI5 interface unit. This interface is described in the Measuring and Scanning Options section. Following figure shows the
cable connection only.

Connection cable from MI5 interface to CNC.

The boards used to interface digital probes are the CPU and the digital I/O board
The CPU board contains 4 channels; the digital probe can be connected to either one of these channels indifferently.
The CPU board manages the Probe status input. If present, other digital I/O signals are managed by the digital I/O board.
The table below shows the signals necessary to connect a digital probe to the NC.

IDRALE Digital input signalling when the milling axis is outside the measurement zone.

* = 0, 1, 2, 3

The standard measuring cycle is as follows:

• The milling axis descends at the "A" feed.
• When the CNC receives IDRAL1 active, the feed of the axis in movement slows down from the "A" value to the "B" value.
• The milling axis descends at the "B" feed until the probe is deflected by a given value. The instrument then sends the signal
probe status signal (IN*) to the CNC which commands the stopping of the milling axis and memorizes the position.

• When IDRAL1 goes to 0V, the milling axis slows down to a slow approach feed.
• Latch of Z axis position.
• When IDRALE goes to 0V, an overdeflection emergency is indicated.

6.2 TM10/MDL OPTION

This option allows for measuring tools mounted on spindles by means of a laser device installed on the machine tool table. It is
used for the following purposes:
• tool length and diameter measurement
• tool length and diameter verification and update
• tool shape validation

The functional blocks necessary for managing the laser tool measurement are:
• n.1 24V power supply source
• n. 2 sections of a digital I/O board (DRTX or DRTXW)
• n. 1 section of a CPU
• n. 1 BICW1 wiring module

The schematic diagram of the connection is shown below. The following signals are available for managing the laser device:
UDRXEN receiver enable
UDTXEN emitter enable
UDEVBP laser device pressure switch enable
UDEVBS laser shutter opener switch enable

The UDRXEN and UDTXEN signals enable laser device through the BICW1 board, while the UDEVBP and UDEVBS signals
are directed to the electrical cabinet.

See the relevant section for the description of the connections with BICW1 module.

6.2.1 DEVICE FUNCTIONAL CHECK

It is important to check the correct ON/OFF functioning of the device (e.g. with the test program): when the laser beam is
uninterrupted, the status signal is “0”; when the laser beam is intercepted, the status signal is “1”.
The laser status signal can be read on the DIG. PROBE page of the TSTC1 test program (see the relevant description).

6.3 TMSC100 TOOL MEASURING SYSTEM

6.3.1 TMSC100 GENERAL DESCRIPTION
The TMSC100 Tool Measurement System consists of a device positioned on the machine tool table and connected via a cable
to the electrical cabinet and therefore to the CNC. It also comprises specific software produced by FIDIA.
Pressurization allows an IP67 degree of protection to be reached. During opening and closing of the shutters, a compressed air
jet removes machining deposits from the shutters. The air flow is commanded by an electrovalve that is external to the TMS.
As a sensor, the device mounted on the machine tool uses a focused red laser beam (λ=670nm). When the tool that is being
measured intercepts the laser beam, this causes the switching of the DOUT signal which is carried, via the serial line, to one of
the CPU dedicated digital probe inputs.

FIDIA MDO1384 6-3

 TMS connected to C type numerical control

Measurement of tool length and diameter

The machine tool position values are recorded with each switching of the signal. By calculating the difference between two
positions measured on opposite sides of the tool, the tool diameter is obtained. The length is determined by calculating the
difference with respect to the length of a sample tool. The system is able to measure tools ranging from 0.1mm to a maximum
of 100mm in diameter.

TMSC100-04 dimensions

6-4 MDO1384 FIDIA

 Standard support plate

The two components comprising the laser sensor (emitter and receiver) are each enclosed in their own module. The modules
are equipped with shutters operated by the commands OPEN/CLOSE. Since the laser beam is focused, the focal point –
located at an equidistant position between TX and RX – is extremely small in size (<0.1mm). All measurements are made at
this point where sensitivity is greatest. The focal point co-ordinates are fundamental measurement data. They are identified at
the time of installation and this operation must be periodically repeated.
The command to open the shutters is executed only if the laser transmitter is on, a condition that is necessary to establish
correct operation of the device.
Each time the shutter is opened, auto-calibration of the laser signal threshold is performed so that the threshold is not subject to
thermal drift.
An alarm logic indicates any operating faults. The NC is informed of any alarm or error situations by means of digital signals.
The interface connector is located to the side of the TMSC100.
The connection for entry of the compressed air is situated on the opposite side.
The electronic board is enclosed within a hermetically sealed container.
The TMSC100 is secured using the groups of four M6 threaded holes, depth 6 mm, located on the lower surface. Additionally,
the support base can be used with its four slots for securing from above.

WARNING
THE TMSC100 USES A CLASS 2 LASER EMITTER (P < 1mW). AVOID DIRECT EXPOSURE OF THE LASER BEAM ON
THE EYES.

FIDIA MDO1384 6-5

6.3.2 OPEN / CLOSE CYCLE
Pressurization has a dual function:
1. to guarantee the IP67 degree of protection
2. to clean the shutters during their opening and closing.

When the TMSC100 is closed, the internal pressure is that set by the filter circuit regulator; a light puff of air escapes from the
shutters. In order to clean the shutters as they open, the pressure must be maintained for a few moments. From the moment
the TMS generates the IDTMSO bit (shutters open), the NC maintains the flow of air for 1 more second; then the DOTMSP bit
is activated (bit that commands the electrovalve) and the air flow is interrupted.

Once the measurement has been made, the pressurization is activated at the same time as the command to close the shutters
(UDTMSC bit = 1). The flow of air is immediate, while the shutters are closed with a delay of approx. 1 second; this delay is
generated by the TMS internal logic. The synchronization of the shutters and air flow is managed by the NC in automatic mode.
In order to check the actual inflow of air to the TMS, a pressure sensor may be positioned after the electrovalve.

It is important that these filtering specifications be respected. Extraneous elements, such as dust and condensate deposited on
the lenses of the lasers, adversely effect the measurement accuracy of the TMS.

6.3.4 ATTACHMENT TO THE MACHINE TOOL

Since the TMSC100 system uses the readout of a horizontal co-ordinate (X or Y) and of the vertical co-ordinate (Z) as
necessary information to determine the dimensions of the tool being measured, it is of prime importance that the device is
securely attached to a part of the machine tool so as to allow for the required TMSC100 / tool to be measured movement.
The typical position is attachment to the table. However, if the table is fixed, there is nothing to prevent the TMSC100 being
secured to any other part of the machine tool, provided the position can be reached by the tool and that it offers sufficient
guarantee of rigidity and stability over time.
The TMSC100 can be attached in either a horizontal or vertical plane, and with or without the support base.
The laser beam must be horizontal. This is for the sole purpose of preventing extraneous bodies (chips, liquids, dust) falling into
the TMS during the measurement phase, i.e. with the shutters open and in the absence of pressure.
If necessary, the TMSC100 can be raised from the table by inserting a connection bracket. Constructed by the user according
to the machine tool and his specific needs, the bracket must satisfy the requirements of high static rigidity, as well as thermal
stability. Any flexion, thermal deformation or oscillation will cause a proportional measurement error in the TMSC100 system.
Application on large machine tools, with their abundant space and, consequently, the need for long axis travel, may make it
advantageous to position the TMS no longer at one end of the table (beyond the work area) but rather in the proximity of the
part. This results in a considerable saving of time during tool measurement cycles.
Naturally, it is necessary to guarantee a safety distance against any risk of impact with the device.
Another extremely important aspect is the alignment of the laser beam with the machine tool axes. During installation optimum
parallelism must be ensured between the TMS reference planes and the machine tool axes. It is extremely important that the
table supporting surface is orthogonal with respect to the axis along which tool length is measured (usually the Z axis). To this
purpose, it is highly recommended that the surface be carefully cleaned before positioning the TMSC100.
Errors owing to incorrect orientation are negligible provided they do not exceed an alignment error of 0.02% between the
machine tool axes and the laser beam.
The TMSC100 can be mounted with the laser beam parallel to one of the two horizontal machine tool axes (usually X or Y).
Once installation has been completed, set the parameters indicating orientation correctly.
Each TMSC100 unit provides access to both sides to pressurization and electrical cables, in order to facilitate the installation on
the Machine Tool table.

6.3.5 CONNECTION TO THE PRESSURIZATION CIRCUIT

The TMSC100 is fitted with an 1/8” gas thread connection for a Ø 8x6 mm tube.
Access is available from both sides.
In order to exchange the position of the threaded connection and threaded plug, proceed as follows:

• firstly, work in a clean environment to avoid dust entering the TMS enclosure;
• remove the ring nut manually;
• remove the connection using a 12mm spanner;
• remove the plug using a 5mm spanner.
• then exchange their position; because of the conical thread, apply a sealant paste or Teflon tape in order to guarantee the
coupling.

The compressed air, filtered as per the specifications, should reach the TMSC100 at a pressure of between 0.6 and 1.2 bar, via
a pressure regulator. The air flow is operated by an electrovalve commanded by the NC. Typically, the name of the bit
commanding the electrovalve is DOTMSP (this is the name used in the Manual, but it can be changed). The DOTMSP output
bit is managed by AUCOL, it is not aTMS signal. FIDIA supplies the necessary source files to generate an AUCOL module that
is able to manage pressurization of the TMS. The files are in \Service\AucolTms and are called:

FIDIA MDO1384 6-7

PLXXXX.PLC
PLXXXX.DEF
PLXXXX.AUC

The AUCOL programmer must perform the following operations:

• Appropriately rename the above files.
• In the.AUCNUM x,USED instruction in the PLXXXX.PLC file, instead of x specify the number of the PLC module.
• Compile and load AUCOL.

6.3.5.1 PRESSURE SWITCH MANAGEMENT

For typical cases in which there is a pressure switch on the main air flow and no further pressure switches are mounted on the
offtakes, management of the pressure switch is not provided.

Consequently, AUCOL instructions relating to management of the pressure switch are preceded by the character ";"
(semicolon), which disables them.
If it is necessary to manage the pressure switch, an input bit (e.g. DITMSP - air pressure switch check) is used and, before
compiling AUCOL, the instructions required must be enabled (e.g. processes P3, P4 and P5) by eliminating the relevant
semicolons from the files.
The manufacturer may also write a different AUCOL program and use it instead of that supplied by FIDIA.

6.3.6 CONNECTION TO THE CNC

Connection to the CNC is by means of a connector mounted on the side of the device.
The connector is the MIL-C 26482 type; the connector and the pin-out are shown in the figure and in the table below.

The cable MCG152 is used for connection between the TMSC100 and the CNC.
This is a 19 conductor cable with a 22AWG section, in twisted pairs, and with colours assigned according to DIN47100
standards. There is an armoured version, code MCG152/A, that has an additional external armour in plaited galvanized iron in
order to protect the rubber sheath in very heavy duty situations (wear by dragging, incandescent swarf, etc.).
The floating connector (TMSC100 side) supplied with the device is the MIL-C 26482 type, series 1 model MS3116-W-14-19S; it
must be inserted in the corresponding connector of the TMS.

6.3.7 CHECKS AND INSTALLATION

6.3.7.1 DEVICE FUNCTIONAL CHECK
It is important to check the correct ON/OFF functioning of the device (e.g. with the test program): when the laser beam is
uninterrupted, the status signal is “0”; when the laser beam is intercepted, the status signal is “1”.
The laser status signal can be read on the DIG. PROBE page of the TSTC1 test program (see the relevant description).
6.3.7.2 CHECKING CONNECTIONS (CHECK MODE)
Before proceeding with installation, some operations should be performed to check that the device is correctly connected to the
CNC. Select the automatic mode and give the following commands in the sequence shown below, using either the software
debugger program or the CNC G220 function (see documentation on software installation).

Sequence of "check mode" commands

Signal OPERATION DESCRIPTION

IDTMSM Check = 1 Connector inserted check
UDTXEN Set = 1 Switching on laser emitter
UDTHRR Set = 1 Selecting laser receiver high sensitivity
UDTMSO Set = 1 Shutters open command ON
IDTMSO Check = 1 Shutters open signal check
DOTMSP Set = 1 Opening air flow
DOTMSP Set = 0 Closing air flow
UDTMSO Set = 0 Shutters open command OFF
UDTXEN Set = 0 Switching off laser emitter
UDTHRR Set = 0 Selecting laser receiver low sensitivity
UDTMSC Set = 1 Shutters close command ON
IDTMSC Check = 1 Shutters closed signal check
UDTMSC Set = 0 Shutters close command OFF

It is possible to continue with subsequent operations only once this command sequence has been executed without error/alarm
situations occurring (IDTMSA must always remain at 0). It is also advisable to check connection of the alarm bit. Each of these
commands may also be given when not in the installation phase, for example during maintenance operations.
6.3.7.3 MEASUREMENT CYCLE
At this point, the focal point co-ordinates are determined and one or more measurement cycles are executed in order to check
that the system is functioning correctly. These measurements must be made using a sample tool with no defects and whose
dimensions are known.
Details of the procedure are given in the documentation on software installation.

6.3.8 MAINTENANCE
Positioning the TMSC100 on the machine tool at the edge of the working area and executing tool measurement cycles in the
intervals between machining cycles are operating conditions that expose the TMS to direct and continuous contact with
machining residues (chips, dust, liquids, etc.). Notwithstanding the IP67 degree of protection, and while adopting the
recommendations as regards supporting and positioning the TMSC100, the fact remains that dust, liquids and chips can
constitute a hazard to operation of the device and therefore to the reliability of the measurements. Constant preventive
maintenance is the best guarantee of reliability. The more the environment is polluted with dust (e.g. graphite dust), the more
machining produces lightweight electrostatic swarf and the more coolant is used, the more frequently preventive maintenance
should be carried out. It may therefore be termed ordinary maintenance.
6.3.8.1 CLEANING THE WORK AREA
The operation to be performed most frequently is keeping the operating zone of the TMSC100 clean. This involves removing
the accumulation of chips or dust in order to prevent any movement of volatile material during measurement that could result in
false commutation of the laser signal.

Manual operation:
With the shutters closed, remove the machining material that has accumulated above the TMSC100 and near the support.

Automatic operation:
Give OPEN and CLOSE commands at short intervals and without interrupting the flow of air. The air jet generated will clean the
area in the vicinity of the TMS. The effectiveness of this operation depends on the air pressure and can vary from one
installation to another.
6.3.8.2 CLEANING THE CAPS
The protective caps on the laser modules are cleaned automatically with each opening and closing cycle. However, should it be
necessary to clean them manually, simply remove the two caps and eliminate any machining residue.

6-10 MDO1384 FIDIA

Important: when the shutters are open and/or in the absence of pressurization, do not use compressed air and take
the greatest care.
6.3.8.3 UNLOCKING THE SHUTTER
At the start of the measurement phase, if the NC indicates an opening error, the shutters are probably blocked. This can
happen when the shutters are particularly dirty and the TMS is without pressurization or has been without pressurization for a
long time, or else is operating with insufficient pressure. First of all, try giving opening and closing commands one after the
other until the shutter unblocks. If this is not sufficient, perform the following procedures manually:
1. remove the pressurization
2. remove the front plug of the module
3. press on the shutter sliding sheet in such a way as to bend it inwards by 1-2 mm; when released, the spring will return the
sheet to its position. Repeat the operation 2 or 3 times. In order not to damage the shutter, use a plastic object with a flat
tip and a diameter of 3 or 4 mm.

If the problem soon re-occurs, internal cleaning is necessary.

6.3.8.4 INTERNAL CLEANING
Internal cleaning is necessary if frequent blockages of the shutter occur or if there is a deterioration in measurement accuracy
that may be owing to the accidental depositing of dust or other substances on the laser glass. A visual check can be made of
the condition of the optical components by looking through the holes on the two modules with the shutters open and the laser
powered off.
The laser module cover must be removed following the procedure below:
1. Close the manual valve upstream from the TMS pressurization circuit, if present; otherwise, interrupt the flow by means of
the DOTMSP bit.
2. Open and close the shutters to release the compressed air that has accumulated downstream from the circuit.
3. Power off the laser; it is advisable to unplug the connector (after powering off) to prevent accidental movements of the
shutter.
4. Remove the four M3x40 front screws attaching the cover (A).
5. Remove the shutter cap (B), without damaging the shutter sliding sheet (C).
6. Clean the dirty components using alcohol: laser glass, shutter cap, shutter sliding sheet.
7. Re-assemble the shutter cap and close, making sure the O-ring is correctly positioned.

Important: do not operate the shutters and do not re-pressurize before the TMS has been completely closed.

IDTMSC and IDTMSO assume the meaning of STATUS BITS when IDTMSA is cleared; they assume the meaning of ERROR
BITS when ITDMSA is set.

STATUS BITS (IDTMSA = 0)

IDTMSC IDTMSO TMSC STATUS
0 0 Undetermined
0 1 Module shutters open
1 0 Module shutters closed

If a time-out occurs during the opening/closing shutters phase, a CNC message is displayed:
• WEX405: closing shutters time-out
• WEX407: opening shutters time-out

In the event of an error, the same IDTMSC and IDTMSO bits give the error coding.
ERROR BITS (IDTMSA = 1)

1 1 ETM048 Error closing laser modules

Notes
• The TMS sets the status bits + error bit to zero when the movement bits (UDTMSC, UDTMSO) are cleared.
• To avoid problems connected with laser warm-up, the UDTXEN bit must always be at 1. However, it should be possible to
switch off the laser for maintenance operations and to perform testing. If UDTXEN is 0, all movement commands are
ignored with the exception of those related to the test.
• A digital filter of 0.5 seconds is applied to all input board bits.

6.3.10 WORK ENVIRONMENT

When the shutters are opened a jet of air escapes from the holes. Depending on the pressure set, the air jet is able to remove
materials deposited during machining from the upper surfaces of the TMSC100 and part of the surrounding area.
This cleaning action may give rise to undesired effects in cases where there are abundant machining residues in the form of
volatile dust (e.g. graphite) in the vicinity of the TMS. An air jet that is too powerful could raise the dust which, remaining in
suspension during measurement operations, can give rise to errors.
The problem is solved by reducing the air pressure. A minimum value of 0.6 bar guarantees an IP67 degree of protection
together with satisfactory cleaning of the shutters and without having any effect on the surrounding environment. With values
below this level, there is no cleaning effect: the TMSC100 operates correctly even without pressurization. However, in this way
there is no automatic and efficient cleaning of the shutters which increases the likelihood of maintenance interventions. IP67
protection is not guaranteed for pressures lower than 0.3 bar.
The problem does not arise for environments with an abundance of liquid or with dust/chips mixed with liquid. There is no
danger of dust remaining in suspension and so, given the viscous properties of the residues, it is advisable to set the pressure
to high values.

6.4 TMSR100 TOOL MEASURING SYSTEM

6.4.1 TMSR GENERAL DESCRIPTION
The TMSR100 Tool Measurement System consists of a device positioned on the machine tool table and connected via a cable
to the electrical cabinet and therefore to the CNC. It also comprises specific software produced by Fidia. As a sensor, the
device mounted on the machine tool uses a focused red laser beam (λ=670nm). When the tool that is being measured
intercepts the laser beam, this causes the switching of the DOUT signal which is carried, via the serial line, to one of the CPU
dedicated digital probe inputs.

6-12 MDO1384 FIDIA

 TMS connected to C type numerical control

The TMSR100 laser modules are mounted on a rotating plate which, depending on the command given by the NC, can take up
four different angular positions: 0°, 45°, 90°,135°. In this way, the TMSR100 can adapt to tool inclination in the case of a bi-
rotary head. The angle must be chosen in such a way that the tool to be measured is as far as possible perpendicular to the
laser beam.

Measurement of tool length and diameter

The machine tool position values are recorded with each switching of the signal. By calculating the difference between two
positions measured on opposite sides of the tool, the tool diameter is obtained. The system is able to measure tool diameters
up to a maximum of 100 mm.

Measurement positions

6-14 MDO1384 FIDIA

The two components comprising the laser sensor (emitter and receiver) are each enclosed in their own module with a degree of
protection of IP65. The modules are equipped with shutters operated by the commands OPEN/CLOSE. Since the laser beam is
focused, the focal point – located at an equidistant position between TX and RX – is extremely small in size (<0.1mm). All
measurements are made at this point where sensitivity is greatest. The focal point co-ordinates are fundamental measurement
data. They are identified at the time of installation and this operation must be periodically repeated.
A focal point must be determined for each position.
The command to open the shutters is executed only if the laser transmitter is on, a condition that is necessary to establish
correct operation of the device. An alarm logic indicates any operating faults. The NC is informed of any alarm or error
situations by means of digital signals.
The interface connector is located to the side of the TMSR100. The electronic board is enclosed within a hermetically sealed
container.
The TMSR100 is secured by means of six M6 threaded holes located on the lower surface.

THE TMSR100 USES A CLASS 2 LASER EMITTER (P < 1mW). AVOID DIRECT EXPOSURE OF THE
LASER BEAM ON THE EYES

6.4.3 TMSR ATTACHMENT TO THE MACHINE TOOL

Since the TMSR100 system uses the readout of the horizontal co-ordinates X and Y and of the vertical co-ordinate (Z) as
necessary information to determine the dimensions of the tool being measured, it is of prime importance that the device is
securely attached to a part of the machine tool so as to allow for the required TMSR100 / tool to be measured movement.
The typical position is attachment to the table. However, if the table is fixed, there is nothing to prevent the TMSR100 being
secured to any other part of the machine tool, provided the position can be reached by the tool and that it offers sufficient
guarantee of rigidity and stability over time.
The TMSR100 must be attached in a horizontal position, using the threaded holes and inserting a connection flange. The
flange, to be constructed by the user according to the machine tool and its requirements, must provide high static rigidity as well
as thermal stability. Any flexion, thermal deformation or oscillation will be a source of proportional measurement error in the
TMSR100 system.
When applying on large machines, with an excess of space and consequently long axis travel, it may be advantageous to
position the TMS no longer at the end of the table (beyond the work area) but close to the workpiece. This results in a
considerable saving in time during measurement cycles.
Naturally, a safety distance must be guaranteed against the risk of impact with the device.
During installation, it must be ensured that there is optimum parallelism between the TMS reference planes and the machine
tool axes. The orthogonality of the TMSR100 supporting surface with respect to the Z axis is extremely important. To this end,

FIDIA MDO1384 6-15

careful cleaning of the surface before positioning the TMSR100 is strongly recommended. Errors owing to incorrect orientation
are negligible provided an alignment error of 0.02% between the work table surface and the laser beam is not exceeded. The X
axis must also be aligned with the reference plane on the rotating plate; the maximum error tolerated in this case is 0.05%.
Alginment must be performed with the TMSR100 in the 0° position, by sliding a comparator over the reference plane.
Subsequent positions are determined by the rotation of the plate which occurs at intervals of 45°.
The TMSR100 can be attached with the laser beam parallel to the machine tool X axis (in the initial 0° position). On completion
of installation, the parameters indicating orientation must be correctly set.
Make sure that the drain hole of the cap looks downwards (see picture); liquids and dust may so flow away without obstructing
the laser beam.

6.4.4 TMSR CONNECTION TO THE CNC

Connection to the CNC is by means of a connector mounted on the side of the device.
The connector is the MIL-C 26482 type; the connector and pin-out are shown in the figure and in the table below.

The cable MCG152 is used for connection between the TMSR100 and the CNC.
This is a 19 conductor cable with a 22AWG section, in twisted pairs, and with colours assigned according to DIN47100
standards. There is an armoured version, code MCG152/A, that has an additional external armour in plaited galvanized iron in
order to protect the rubber sheath in very heavy duty situations (wear by dragging, incandescent swarf, etc.).
The floating connector (TMSR100 side) supplied with the device is the MIL-C 26482 type, series 1 model MS3116-W-14-19S; it
must be inserted in the corresponding connector of the TMS.

6.4.5 TMSR CHECKS AND INSTALLATION

6.4.5.1 DEVICE FUNCTIONAL CHECK

It is important to check the correct ON/OFF functioning of the device (e.g. with the test program): when the laser beam is
uninterrupted, the status signal is “0”; when the laser beam is intercepted, the status signal is “1”.
The laser status signal can be read on the DIG. PROBE page of the TSTC1 test program (see the relevant description).

6.4.5.2 CHECKING CONNECTIONS (CHECK MODE)

Before proceeding with installation, some operations should be performed to check that the device is correctly connected to the
CNC. Give the following commands, in the sequence indicated, using either the software debugger program or the CNC G220
function (see documentation on software installation).

N.B. Since this is a manual type operation, acting on one bit at a time, it is not possible to rotate the TMSR100 and so the
UDTMSS driver selection bit should remain at 0. The procedure tests basic TMS functions (opening/closing of shutters) and
connection continuity except for the UDTHRR and UDFILS bits.

Signal OPERATION DESCRIPTION

IDTMSM Check = 1 Connector inserted check
UDTXEN Set = 1 Switching on laser emitter
UDTHRR Set = 1 Selecting laser receiver high sensitivity
UDTMSO Set = 1 Shutters open command ON
IDTMSO Check = 1 Shutters open signal check
UDTMSO Set = 0 Shutters open command OFF
UDTXEN Set = 0 Switching off laser emitter
UDTHRR Set = 0 Selecting laser receiver low sensitivity
UDTMSC Set = 1 Shutters close command ON
IDTMSC Check = 1 Shutters closed signal check
UDTMSC Set = 0 Shutters close command OFF

Sequence of "check mode" commands

It is possible to continue with subsequent operations only once this command sequence has been executed without error/alarm
situations occurring (IDTMSA must always remain at 0). It is also advisable to check connection of the alarm bit. Each of these
commands may also be given when not in the installation phase, for example during maintenance operations.

6.4.5.3 MEASUREMENT CYCLE

At this point, the co-ordinates of the four focal points are determined, one for each angular position of the TMSR100, and one
or more measurement cycles are performed to check that the system is functioning correctly. These measurements must be
made using a sample tool with no defects and whose dimensions are known.
Details of the procedure are given in the documentation on Software Installation.

6.4.6 TMSR MAINTENANCE

Positioning the TMSR on the machine tool and at the edge of the working area, executing tool measurement cycles in the
intervals between machining cycles - these are very exposed operating conditions and constitute a risk.
Notwithstanding the degree of protection, and while adopting the recommendations made as regards supporting and
positioning the TMSR, the fact remains that dust, liquids and swarf can constitute a hazard to operation of the device and
therefore to the reliability of the measurements. To this must be added the risk of impact with suspended weights during the
loading/unloading of the part, as well as impact against the tool itself during approach/withdrawal sequences from the
measurement area. Constant preventive maintenance is the best guarantee of reliability.
The more the environment is polluted with dust (e.g. graphite dust), the more machining produces lightweight electrostatic swarf
and the more coolant has to be used, the more frequently this maintenance should be carried out. It can therefore be termed
ordinary maintenance.
The operation to be performed most frequently is keeping the operating zone of the TMSR clean. With the shutters closed,
remove the machining material that has accumulated from above the TMSR and from near the support so as to prevent any
movement of volatile material during measurement.
A less frequent operation is cleaning the protective caps of the laser modules. Remove the two covers and eliminate any
machining residue.
Important: when the shutters are open, do not use compressed air and take the greatest care. When replacing the caps, make
sure the discharge hole is oriented downwards.
If a deterioration in measurement accuracy is detected, this may be due to accidental depositing of dust or other substances on
the glass of the laser. A visual check can be made of the condition of the optical components by looking through the holes on
the two modules with the shutters open and the laser switched off.

In order to cleaning the lenses remove the laser module following the procedure reported below:

6-18 MDO1384 FIDIA

• disconnect the TMS (unplug the connector);
• remove the n.4 M3x40mm screws holding the cover (A)
• remove the shutter cap (B), without damage the shutter sliding sheet (C).
• remove with alcohol the dirt from laser, shutter cap, shutter sliding sheet.
• re-assemble the shutter cap and close, paying attention to the correct position of the O-ring

Notes
• The TMS sets the status bits + error bit to zero when the movement bits (UDTMSS, UDTMSC, UDTMSO) are cleared.
• To avoid problems connected with laser warm-up, the UDTXEN bit must always be at 1. However, it should be possible to
switch off the laser for maintenance operations and to perform testing. If UDTXEN is 0, all movement commands are
ignored with the exception of those related to the test.
• A digital filter of 0.5 seconds is applied to all input board bits.

7 TRACERS
7.1 GENERAL HARDWARE DESCRIPTION
Copying options require an interface between the tracer and the Numerical Control. The board used for interfacing analog
tracers is the TEX board -Tracer Board. The tracer management is carried out by the standard pushbutton panel.
The FIDIA Numerical Control supports tracers with D.C. output voltage Vout ≤ ±10 V d.c., by means of an interfacing board
located inside the chassis, plugged at the axis board. See Chapter TEX1 - Analog Tracer Expansion Board for further details.

7.1.1 CONNECTION TO FIDIA TRACERS

Figure below shows an example of connection to a FIDIA K family analog tracer. Some digital inputs are necessary for the
management of the tracer. These inputs must be connected to the TEX board and are as follows:
IDTAM -> ID00 - pin 25.
IDASD -> ID01 - pin 7.

7.4 MQR10 OPTION - MEASURING AND SCANNING OPTIONS

The MQR10 option uses digital probes and is used for measuring cycles. The board which allows for interfacing with the CNC is
the CPU. Up to four digital probes may be interfaced. So four digital outputs and four differential inputs are available.
Connection examples are shown in fig. 6.1 where the digital probe is shown as a switch which changes its idle status when a
deflection occurs.
There, the differential input is not used is connected to the PULL-DOWN pins ("PD ").
If the output switch of the digital tracer is normally open, the +IN pin must be connected to the PD pin.
If the output switch is normally closed, the -IN pin must be connected to the PD pin.
There is one other input which is negative only (-IN3) and can be used solely for tracers with normally open switches.
In order to have a better understanding of the connections between the CNC and a digital probe, figure below shows the
interfacing of one tracer with normally open outputs and one tracer with normally closed outputs.
The CPU board contains 4 channels; the digital probe can be connected to anyone of these channels.
The CPU board manages the Probe status input. If present, other digital I/O signals are managed by the DRT board.
On the NCs provided only with one CPU (+ one possible CPU for Aucol), the probes must be connected to the first CPU.
On the NCs provided with three CPUs (+ one possible CPU for Aucol), the probes must be connected to the third CPU.
The table below shows the signals necessary to connect a digital probe to the NC.

As shown above, the CPU board can interface different types of digital probes. Each digital probe requires a series of control
signals which vary according to the features of the probe.
Therefore the customer must know the features of the particular probe used and then select the correct signals on the CPU and
digital I/O board. Some examples are given below for interfacing different types of digital probes.

7.5 MQR10/C3 OPTION

The MQR10/C3 Option enables digital probes to be used in order to carry out measuring cycles for checking moulds and dies,
models and mechanical parts in general.
In order to automate measuring and reading operations, the data measured can be recorded either in the system memory, on a
floppy disk or printed.

NOTE - The CNC control provides a series of Automatic Cycles for measuring dimensions. These are described in the "User's
Manual".

8 HANDPENDANT PUSHBUTTON PANELS
8.1 HANDWHEELS
Fidia interfaces handwheels which signals comply with Fidia Digital Counting channels (on MFB1 or PCX1 boards), either
single ended or differential. C Class manages up to three handwheels, one of which may be located in the pendant, next to the
monitor, in the auxiliary panel, the second in a user remote box and the third being a HPX - HPJ type handwheel. The remote
box may host a handwheel with pushbutton or selector for axis selection.
Further Fidia provides two types of handwheels, depending on the size; details follow.

MAV011 Mechanical dimensions

MAV171 Handwheel

FIDIA MDO1384 8-1

The handwheel manages only one axis at a time and affects the movement of the machine occording to a resolution factor
detected by the resolution button (main C Class pushbutton panel) or the position of a selector (User remote box).
The handwheel interface is a standard package in C Class but several possibilities are available:
• the handwheel is located close (or attached) to the pushbutton panel;
• the handwheel is part of the PSC1 auxiliary panel, or C10/C20 pushbutton panel, or located in the User service panel;
• the handwheel is part of a User remote box;
• the handwheel is part of a HPX/HPJ unit.

In the first two cases the handwheel is interfaced through the push-button i/o signals for axis enable and resolution factor.
Of course the counting port shall be connected; refer to MFB1 or PCX1 digital counting chapters for details.
The third case, in addition to the counting signals, requires the signals for handwheel resolution and axis selection.
The forth case is described in the relevant chapters.
In the case of a remote box, the axis selection may be of two types:
• via pushbuttons, each with its own lamp; the CNC enables the axis (if not yet selected on the main C Class pushbutton
panel) when axis button is pressed and disables it if pressed twice or another axis button is pressed;
• via a selector; once selected, the axis is enabled by pressing an ENABLE button (the CNC approval is shown on the
relevant ENABLE lamp).

In this option the digital transducer is used in unipolar mode and the digital counting board must be set accordingly, (see MFB1
- Multifunction Board or PCX1 - Serialized Pushbutton Board ).

• PSC1/01 Additional service pushbutton panel with handwheel (C1 and C2 only)
• PSC1/02 Additional service pushbutton panel without handwheel (C1 and C2 only)
• PSMC/01 Kit for 9 additional pushbuttons without handwheel (C20 only)

8.2.1 PSC1-01 SERVICE PANEL

The service panel contains:
• an emergency button, to be connected in series with the emergency line;
• n.9 5V pushbutton and lamp I/O signals which meaning may easily customised by the user, either by the C_GEN utility
(relating to sw files) or by printing the desired symbols on transparent sheets and then placing the 10mm square
underneath the plastic lens of the button; these signals are linked to the MFB1 (address #34) or PCX1 board via a flat
cable;
• n.1 electronic handwheel (the same as that used on HP* units); the signals shall be linked (for example) to the MFB or
PCX1 board by the customer; signals are unipolar;
• n.2 key switches for user functions (i.e.:NIGHT); 42V @250 mA is the maximum power allowed on contacts; the keys are
differently shaped and recognizable by a letter L or R punched on the key itself, so for accomplishing safety rules;
• a round-flat cable for remoting digital I/Os to MFB1_#34L port or to PCX1 and a series of connectors for all other
connections, (for example to C1 boards or to wiring modules or, else, to user service units).

8.3 HPX/HPJ HAND PENDANT OPTIONS

8.3.1 HAND PENDANT OPTION GENERAL DESCRIPTION
The HP* is a handheld pusbhutton panel connected to the CNC via the FBUS and used specifically for machine tool movement.
In spite of its small size, the handheld pushbutton panel can perform most of the functions of the pushbutton panel mounted on
the workstation (depending on the configuration chosen by the customer). Use of the handheld pushbutton panel enables the
operator to work in close proximity to the part while maintaining control of the machine tool.
More than one pushbutton panel (maximum 2) can be used alternatively with different functions.

The device meets the standards

EN60204-1 (Safety of machinery - Electrical equipment of machines)
EN50081-2 (EMC - Generic Emission Standard) and
EN61000-6-2 (Generic Immunity Standard, Industrial Environment)
Emergency stop switch in accordance with EN418 (Safety of machinery).

8.3.2 GENERAL SPECIFICATIONS

The pushbuttons and lamps can perform the same functions as the pushbuttons/lamps on the main pushbutton panel.
Alternatively, they can perform other functions implemented on request by means of the FIDIA AUCOL programming language.
When there is more than one HP* pushbutton panel, one panel only can be enabled for use at a time. Commands can be
exchanged between different pushbutton panels only when the spindle is at rest and with the START pushbutton flashing, i.e.
while awaiting commands. The physical displacement of handheld pusbhutton panels connected to the same system is
allowed. This means that each HP* may be connected to any connector provided for this purpose; however, this physical
exchange must take place when the system is switched off. When an HP* pushbutton panel is enabled, the commands doubled
on the main pushbutton panel are disabled. The emergency pushbutton and any display are active on the HP* that is enabled.
However, the pushbuttons, handwheel and Feed and Spindle override potentiometers are active only while the user holds down
both “Dead Man” side pushbuttons (the release of one or both Dead Man pushbuttons automatically deactivates the relevant
functions). The key switch must be in the ON position (green LED illuminated) for the HP* pushbutton panel to be enabled for
operation. If another pushbutton panel with its switch in the ON position is already present on the machine, it should be
disabled and then the first panel enabled. In order to enhance the safety level of the system, it is recommended that one key
only be provided for the machine tool operator, regardless of the number of pushbutton panels available. If an attempt is made
to enable one HP* panel when another panel is already enabled, or to give a command using a pushbutton panel that is not
enabled, an error message will be displayed on the monitor. Up to n.2 HP* units may be linked on a Fbus, fully independent. In
case of twin consol system, the console switching does NOT affect the HP* enabling.

FIDIA MDO1384 8-11

Currently, there are two models:
• HPX20 with handwheel, display, 2 potentiometers and 19 pushbuttons.
• HPJ20 with handwheel, one potentiometer and 7 pushbuttons.

8.3.4 HPX20
A 9-digit display shows the position value, while the handwheel or JOG+ and JOG- pushbuttons are used to command the axis
selected. The display can show other data, such as axis feed and spindle rotation speed. The axis to be moved and the
handwheel resolution are selected by means of pushbuttons. 16 pushbuttons are provided to command different
movement/cycle execution operations. Using the two feed override and spindle override potentiometers, the axis feed and
spindle speed set via the keyboard can be varied from 0% to 200%, and from 50% to 150%, respectively.
Detailed features of the HPX20 pushbutton panel are as follows:
• Red emergency pushbutton (top).
• 2 “Dead Man” side pushbuttons; these are used to confirm operation.
• 1 green LED (top right): illuminated = pushbutton panel enabled, not illuminated = disabled
• 2 arrow pushbuttons ⇐ and ⇒ to select the axis to be moved (X, Y, Z, 4, 5, 6, 7, 8). When an axis is selected, the
corresponding LED lights up. OFF can also be selected (no axis selected).
• 8 red LEDS (X, Y, Z, 4, 5, 6, 7, 8): an illuminated LED indicates an axis that has been selected for movement and identifies
the data shown on the display (axis position value).
• 9-digit + sign display to show axis position value or feed.
• 3 red LEDs (1, 10, 100) + an arrow pushbutton ⇐ to select handwheel resolution. Choose from: 1, 10, 100 and OFF
(handwheel disabled). When a resolution is selected, the corresponding LED lights up. When all three LEDs are off, this
means that the handwheel is disabled.
• 16 general purpose luminous pushbuttons, with functions that can be defined as requested.
• Spindle override potentiometer from 50% to 150%.
• Feed override potentiometer from 0% to 200%.
• Electronic handwheel 100 impulses/revolution.

When the Feed potentiometer is turned, the display shows the axis feed (preceded by the character F) for a few moments,
before automatically returning to the previous display. When the spindle is rotating and no axes are selected, the display shows
the spindle rotation speed, preceded by the character S.
A CM10/037 is available in C_Gen for managing Feed and Spindle functions (F and S) also by pushbutton; memory bits
IDPHDF and IDPHDS may be allocated to any of the 16 pushbuttons so that, without changing the F or S value:
• when pressed the display shows the value of F or S
• when released the axis position value is displayed.

8.3.5 HPJ20
With this pushbutton panel, an axis can be moved via the handwheel or using the JOG+ and JOG- pushbuttons. The axis to be
moved and the handwheel resolution are selected by means of pushbuttons. Four pushbuttons are used to command different
movement/cycle execution operations. The override feed potentiometer can regulate the feed set from the keyboard by 0% to
200%. Detailed features of the HPJ20 pushbutton panel are as follows:
• Red emergency pushbutton (top).
• 2 “Dead Man” side pushbuttons; these are used to confirm operation.
• 1 green LED (top right): illuminated = pushbutton panel enabled, not illuminated = disabled
• 8 red LEDs (X, Y, Z, 4, 5, 6, 7, 8) + 2 arrow pushbuttons ⇐ and ⇒ to select the axis to be moved. When an axis is selected,
the corresponding LED lights up. OFF can also be selected (no axis selected; in this case, all the LEDs are off).
• 3 red LEDs (1, 10, 100) + an arrow pushbutton ⇐ to select handwheel resolution. Choose from: 1, 10, 100 and OFF
(handwheel disabled). When a resolution is selected, the corresponding LED lights up. When all three LEDs are off, this
means that the handwheel is disabled.
• 4 fixed functions luminous pushbuttons.
• Feed override potentiometer from 0% to 200%.
• Electronic handwheel 100 impulses/revolution.

There are two cables available for the HP*-CNC connection: MCG158 and MCG159.
Both cables are for mobile laying. Both have a general shield. The MCG159 cable has an extra external braided galvanized iron
armature to protect the rubber insulation from particularly heavy work situations (wear from dragging, incandescent chips, etc.).

The connection of the HP* portable pushbutton panel may develope in two different ways:
• the signals run to an EXTW1 wiring module (located in the electrical cabinet) and then handed out to the Fbus boards and
Emergency logic. this solution is forced on C1 system configurations but also may be employed on C2/C10/C20 systems
(for example if the hand pendants are located far from operator consoles).
• the console receives and distribute the signals; a cable takes the place of the EXTW module. This solution is available (and
highly recommended) for C2/C10/C20 systems.

The following paragraphs show the details.

8.3.7 CABLE ENDINGS AND CONNECTIONS

8.3.7.1 CABLE ENDINGS
When the HP* unit is unplugged or the line is not working (see example in figure) you may use the Ume150.m plug, supplied
along with the UME150 or UME148 option. The plug closes internally the emergency contacts and loops back the RX-TX lines.

Ume150.m plug on PF14

8.3.7.2 INTERMEDIATE CONNECTIONS
In order to plug the HP* unit the customer may like to split the line into segments instead of using a straight cable from the
interface board to the HP* unit.
The junctions may be flying socket or on a panel.
Connectors MCN423 and MCN424 may be used in the first case, MCN425 in the second.

Link through EXTW1 board - junction on a panel

The connection between HP* and CNC may, of course be "direct" to EXTW board; this solution, though, is NOT advisable,
since it implies a difficult management in case of damage to HP*; in fact, it implies that the customer or a service engineer
exchanges the unit by opening it and transferring the cable to the new unit. For this reason, it is recommended to split the "long"
cable in two, either with a in-line or a side wall interconnection.

8.3.8 HPX/HPJ INTERFACE THROUGH EXTW BOARD

The signals are distributed from the EXTW module to the CNC and the other modules (see example below).

Example of the connection of hand pendants on C1 systems

Example of the connection of hand pendanst on C2/C10/C20 systems

It is recommended that HP* hand pendants be installed as indicated in the above figure, i.e. in an intermediate position in the
serial line. In this case the FBUS termination is executed on the last DRTX module. If hand pendants are exchanged, the line
continues to be terminated and perfectly functioning.
Care should be taken when exchanging hand pendants; this should be done when the machine tool is at rest.
All FBUS line connections between the various modules in the cabin must be made using shielded cables. The RT+ and the

FIDIA MDO1384 8-19

RT- signals must travel on twisted conductor pairs. The cable shield must be soldered to the EXTW side.

The following examples show how to proceed to interface HP* through EXTW board.

See detailed information on the HP* link in the relevant section CABLE ENDINGS AND INTERMEDIATE CONNECTIONS.

Notes for the following drawings:

The --| or |-- symbols indicates a connector. The word DBXX-Y indicates the type of the connector:
XX = number of pins
Y = P (male) or S (female)

HP* wiring overview - Example

8.3.9 HPX/HPJ INTERFACE THROUGH CONSOLE

On C2/C10/C20 system configurations a direct link between hand pendants to the console through a connector located aside
the console itself is recommended, thus making a neat and easier wiring which also saves hardware ports on the interface rack
(particularly useful for full-option exhaustive configurations) and reduces possible noise on FBUS (by shortening the extension
cable running through the workshop).
Within the console chassy, the signals are taken from the round connector and divided for CNC management and PLC logic
management. The cable available from FIDIA is coded as UME148.

If a 2 operator console is present, but only one HP* unit is available, please note that:
• moving the HP* unit to one operator console to the other, it is Compulsory to switch the machine off (EMERGENCY);
• a UME150 plug (bypass connector) should be inserted at the end not connected to HP*. Such connector should carry a
loopback on EMERGENCY and FBUS wires.

The "Dead man" bits (IDHP*R, IDHP*L) are essential for safety management of the machine tool.

8.3.11 INSTALLING THE HPX AND HPJ HAND PENDANTS

8.3.11.1 SETTING THE JUMPERS
It is necessary to gain access to the internal electronics of the hand pendant only to set the jumper for assigning the address to
2nd HP*. To open the hand pendant, release the 4 screws on the back. When closing the hand pendant, check that the O-Ring
is positioned correctly in the special groove and that the cables do not interfere while closing. Do not screw the screws too
tightly because there is a risk of unscrewing the spacers.

9 iPC INTEGRATION IN THE WORKSHOP
9.1 ETHERNET LAN
Ethernet networks consist of several network stations connected together to allow electronic communication between stations.
Network stations can be file servers, bridges, print servers, network stations or other nodes on the network.
The network stations on a thin or thick network are connected at intervals to one long main cable, referred to as the trunk
segment cable. The network stations and the main cable together form a trunk segment.

The thin-Ethernet trunk segment cable is usually made up of a series of cable lengths connected with connectors, rather than
one continuous cable.
The trunk segment is limited to a maximum length and a maximum number of stations that can be accommodated. However, a
network can be expanded beyond one trunk segment by linking two or more trunk segments together with a repeater.
A repeater forms a pathway for network signals traveling from one trunk segment to another; it also amplifies network signals.
The network trunk cable is the sum of all the trunk segment cables. Just as a trunk segment cable is the backbone of a trunk
segment, the network trunk cable is the backbone of the entire network.
There are three kinds of Ethernet cable, thin-Ethernet coaxial cable (type RG-58 A/U), thick-Ethernet coaxial cable, and UTP-
Ethernet cable (Unshielded Twisted Pair).
These kinds of Ethernet cable can be used to build a wide variety of Ethernet cabling systems.
The UTP cable have 8 wire (4 pair) of 24 AWG gauge and use RJ-45 connector type.

9.1.1 THIN-ETHERNET CABLE NETWORK HARDWARE

The hardware needed to set up a thin-Ethernet cable network is shown in the following figure.

FIDIA MDO1384 9-1

Network Board
A network board is a printed circuit board. Network boards are inserted into an expansion slot in each network station and
cabled together to allow electronic communication between network stations.

BNC Connectors
BNC jacks and plugs connect network hardware. The BNC jack on a network board connects the board to the trunk segment
cable. The BNC plugs, at each end of thin-Ethernet cable lengths, connect the cable to T-connectors, barrel connectors, and
other hardware.

Thin-Ethernet Cable
Thin-Ethernet cable is type RG-58A/U 50-ohm coaxial cable. It is available in pre-cut lengths of 20 feet, with a standard BNC
connector plug attached to each end. Thin-Ethernet cable is also available from other industry suppliers in bulk quantities;
however, bulk cable does not come with connectors attached.

BNC Barrel Connectors

BNC barrel connectors join two lengths of thin-Ethernet cable.

BNC T-Connectors
The two opposing jacks of the T-connector act as a barrel connector and join two lengths of thin-Ethernet cable. The remaining
plug attaches to the BNC jack on a network board installed in a network station.

BNC Terminator
A BNC 50-ohm terminator "terminates" the network and absorbs electrical interference on the network. It is attached to one of
the two jacks on a T-connector at the end of a trunk segment. Some BNC terminators also ground the network; these come
with a grounding wire attached. You must use BNC terminators (one end with a grounding wire attached as shown in figure,
and one end without a grounding wire) to properly install an Ethernet network.

9-2 MDO1384 FIDIA

With the FEB100 option, only the RJ45 plug is available on the board.

9.2 REMOTING THE FLOPPY DISK DRIVE

The FIDIA iPC has a built-in 3"½ drive; access to the drive is from the rear of the operating unit on C1, and from the front of the
interfacing rack on C2/C10/C20.
In case of frequent access to the drive an option is available from Fidia to remote the data and power cables.
Following are two ways of remoting, depending on the C configuration:
• on C1 the customer must provide a safe box for hosting the drive and an extension for data and power cable, or the option
available from FIDIA by the code KRF/01. The pictures below show a sample of cables for Customer usage; the maximum
length allowed is 100 cm.

FIDIA code KRF/01 consists of a metal box housing the floppy, a cable extension internally located in the iPC, and a set of
external data and power cable (max. length 100 cm).

• On C2/C10/C20 the floppy disk unit may be remoted on the electrical cabinet (max. length 100 cm) using the same FIDIA
code KRF/01.

FIDIA MDO1384 9-3

 For longer distances (up to 50 m) , for remoting the drive aside the command module, an option is available (FIDIA code
KRF/02).
A 2-ways terminal block is available for a 24V ±10% 10W power supply, which must be provided on Customer care.
The terminal block is located on the box to be mounted near the console, as shown in the drawings below.

Following are the details:

9.3 PAD14/02 MOUSE PAD

A mouse pad is available for installation on the right end side of the PF14 chassy.
It includes a Mini-DIN internal cable that will replace the cable of the internal mouse (which remains there, wrapped for use in
case the external mouse is no longer used).
If the internal mouse is disconnected and no external mouse is hooked to the extension to the rear of the chassy, the Operating
System shows an error at start up; in such case, switch the computer off (following the power off procedure), check the cables,
connect the internal mouse and restart.

Limitations:
On C2/C10/C20 configurations the mouse signal is processed and sent through a Fidia interface board; not all mice and their
software drivers may be compliant to the PS2 standard protocol and may require proprietary driver installation; this installation
of such drivers may affect the Operating System environment therefore we STRONGLY SUGGEST to install mouse using the
standard Microsoft PS2 STANDARD DRIVER.
For special installations you may contact the Sales Dept. or Service Dept.

10 APPENDIX A - TESTS
10.1 TEST PROGRAM AND CHECKING
The test program is used in order to:
check that the connections of each signal correspond to the C_GEN listing;
check at the logic level that the connections have been made correctly.

10.1.1 RUNNING THE TEST PROGRAM

• Power on the machine tool. If the system is the C2/C10/C20 type, it is important that the interface module (rack) and
command modules (consoles) are powered on together. Otherwise the following order should be respected: first the
consoles and then the rack.
• Wait for start-up of Windows.
• If Windows automatically starts the CNC command interface, this must be closed by selecting Exit from the File menu.
• From the Windows tool bar: click on the Start button, select Programs, select the Fidia Utility file and then click on C1
Maint.This opens the window for using SID (System Integrated Debug), a program necessary for debugging and for loading
the application software. The command prompt > appears in the window.
• Press the TSTC1 soft key. The test program for the boards is run.

Procedure for exiting from the test program

• Press the Exit TSTC1 soft key from the main page.
• Close the Fidia Maint window by selecting Exit from the File menu.

At this point, if necessary, the CNC command interface can be started: from the Windows tool bar, click on the Start button,
select Programs, select the Fidia Utility file and then click on User Interface.

10.1.2 TEST PROGRAM MAIN PAGE

After giving the command TSTC1, the Main Page of the test program is shown on the screen.

This is the starting point to get to the TEST PAGES

10.2 DISPLAYING THE BOARDS

Procedure for displaying a board:

FIDIA MDO1384 10-1

• Display the Main Page of the test program.
• Press arrow keys to select the function desired.
• Press the ENTER key to display the page for the board. Press ENTER once more to return to the Main Page.
• Since the Test Program is for general use, some of the functions possible are not relevant to this manual.
• It is recommended that reference be made exclusively to functions that are dealt with specifically in this manual in order to
avoid possible malfunctions.
• The Test Program contains some general commands that are effective in all conditions:
• <CTRL C> Stops execution of the Test Program and returns the control to SID.
• <CTRL R> Initializes the Test Program.
• <CTRL V> Rewrites the current page.
• <CTRL O> Selects display of the addresses in octal code.
• <CTRL H> Selects display of the addresses in hexadecimal code.
• <CTRL N> Displays the sequence number of a board, instead of its address in octal or hexadecimal code. It is used to
display the number of each DRTX boa rd. As the other boards are always in single copy, for these it is displayed the
number one.
• <TAB> Clears all the CNC outputs.
• <+> <-> A numerical value must be preceded by its sign.
• ARROW KEYS Move the cursor inside a table.

10.2.1 DRTX* FUNCTION - DIGITAL INPUT/OUTPUT

The following table is shown on the screen:

This table is divided into four parts, each of which shows the bits of a “DRT” module, i.e. a DRTX board, a DRTXW board or an
MFB DIGITAL connector.
The bits are numbered from 0 to 31 starting from the right, following the indication given in the top two lines of the table (for
example, 1 above 5 is read as 15).
The DRT modules displayed as #33 and #34 correspond to the signals that are accessible on MFB DIGITAL connectors #33 -
#34 on the CNC rear panel.
The other DRT modules are present only if there is an FBUS line.
If the system has more than four DRT modules, subsequent modules can be displayed by positioning the cursor in the ADX
field and pressing the space bar.
Remember that the 32 bits of a DRTX/DRTXW board can be connected to both digital inputs and digital outputs.

10-2 MDO1384 FIDIA

The lines of 32 bits marked with OUT represent digital outputs; the lines of 32 bits marked with IN represent digital inputs.
By positioning the cursor on an individual bit in an OUT line and pressing the X key, the logic state of the bit is changed.
To drive the physical device commanded by that bit, the digital signal ENOUT must be set to 1. If this is not the case, it is
possible to enable the outputs by setting to 1 the first bit to the left of the CTRL field (this operation is of no use for DRT
modules #33-#34 since these are always enabled). If a digital output is set to 1, the corresponding bit representing the input
also assumes state 1 (DRT modules #33-#34 are exceptions because their inputs and outputs are not connected together).

10.2.2 MFB1 FUNCTION - ANALOG INPUT/OUTPUT

The following tables are shown on the screen:

OUTPUT Table
Allows for reading/writing of the analog outputs of the MFB1 board. Each line represents a signal; channels 02-03 are present
only if the AEX1 board is included. The value of each signal is represented in bit form and in numerical form. The bits are
numbered from 0 to 15 starting from the right, following the indication given in the top line of the table. The numbers of bits to
the left of 9 are read placing 1 before the digit indicated. The “Volt” column shows the relevant value in millivolts (from -10000 to
10000). The value of each individual output can be changed in one of two ways:
• modifying the logic state of individual bits in the OUTPUT column: by positioning the cursor on an individual bit and
pressing the X key the logic state of the bit is changed;
• entering the desired value in millivolts in the “Volt” column (starting with the character + or -); the value must then be
activated by pressing the ENTER key.
By positioning the cursor on the “CLR” column and pressing the X key, the corresponding analog output is cleared.If the same
operation is performed but with the “COM” column, the sign of the corresponding output is changed.

INPUT Table
Allows for reading of the analog inputs of the MFB1 board. Each line represents a signal; channels 04-05 are present only if the
AEX1 board is included. Channels 06-07 correspond to unipolar inputs. The value of each signal is represented in bit form and
in numerical form.The bits are numbered from 0 to 12 starting from the right, following the indication given in the top line of the
table. The numbers of bits to the left of 9 are read placing 1 before the digit indicated. The “Volt” column shows the relevant
value in millivolts (from -10000 to 10000).

10.2.3 MFB1 FUNCTION - DIGITAL COUNTING

The following table is shown on the screen:

FIDIA MDO1384 10-3

This table represents the three MFB1 board digital countings. The meaning of the lines depends on the code letter(s):
C counting value ( = counting number)
I index value
CS status register

On each C# and I# line, the counting value is represented in bit form and in numerical form. The bits are numbered from 0 to 15
starting from the right, following the indication given in the top line of the table. The numbers of bits to the left of 9 are read
placing 1 before the digit indicated. The “SPEED” column shows the speed of each of the axes in movement and the
“POSITION” column their position in relation to zero. By positioning the cursor on the “RES” column and pressing the X key, the
position values of the corresponding axis are cleared. Bits 1, 5 and 9 of line CS indicate detection of an index pulse. Bits 2, 6
and 10 indicate a counting error. Bits 3, 7 and 11 indicate the status of the FAULT input. Since these bits are continuously
updated, it is difficult to display them. In order to facilitate a reading, the status of these bits can be lockek when they become
active by setting the LATCH I/F/ERR BIT ON COUNT option to ENABLE on the TEST OPTIONS page (press the vertical TEST
OPTIONS soft key, press the ARROW UP/DOWN keys to select the option and then press the space bar until the desired value
has been entered).

10.2.4 DAB1 FUNCTION - ANALOG OUTPUT

The following tables are shown on the screen:

10-4 MDO1384 FIDIA

OUTPUT Table
Allows for reading/writing of the analog outputs of the DAB1 board.Each line represents a signal. The value of each signal is
represented in bit form and in numerical form. The bits are numbered from 0 to 15 starting from the right, following the
indication given at the top of the table (for example, 1 above 3 is read as 13). The “Volt” column shows the relevant value in
millivolts (from -10000 to 10000).The value of each individual output can be changed in one of two ways:
• modifying the logic state of individual bits: by positioning the cursor on a bit and pressing the X key the logic state of the bit
is changed;
• entering the desired value in millivolts in the “Volt” column (starting with the character + or -); the value must then be
activated by pressing the ENTER key.

By positioning the cursor on the “CLR” column and pressing the X key, the corresponding analog output is cleared.If the same
operation is performed but with the “COM” column, the sign of the corresponding output is changed.
MFB1 INPUT TableAllows for reading of the analog inputs of the MFB1 board. It is not normally used. It is similar to the INPUT
table on the MFB1 ANALOG page, described in the relevant paragraph.

10.2.5 DAB1 FUNCTION - DIGITAL COUNTING

The following table is shown on the screen:

This table is divided into two parts, each of which shows the three DAB1 board digital countings.
The meaning of the lines depends on the code letter(s):
C counting value ( = counting number)
I index value
CS status register

On each C#and I# line, the counting value is represented in bit form and in numerical form. The bits are numbered from 0 to 15
starting from the right, following the indication given in the top line of the table. The numbers of bits to the left of 9 are read
placing 1 before the digit indicated. The “SPEED” column shows the speed of each of the axes in movement and the
“POSITION” column their position in relation to zero.By positioning the cursor on the “RES” column and pressing the X key, the
position values of the corresponding axis are cleared.Bits 1, 5 and 9 of line CS indicate detection of an index pulse.Bits 2, 6 and
10 indicate a counting error.Bits 3, 7 and 11 indicate the status of the FAULT input.Since these bits are continuously updated, it
is difficult to display them. In order to facilitate a reading, the status of these bits can be locked when they become active by
setting the LATCH I/F/ERR BIT ON COUNT option to ENABLE on the TEST OPTIONS page (press the vertical TEST
OPTIONS soft key, press the ARROW UP/DOWN keys to select the option and then press the space bar until the desired value
has been entered).

FIDIA MDO1384 10-5

10.2.6 TEX1 FUNCTION - ANALOG TRACER
The following tables are shown on the screen:

The INPUT table allows for reading of the analog inputs of the TEX1 board.Each line represents a deflection signal.The value
of each signal is represented in bit form and in numerical form.The bits are numbered from 0 to 15 starting from the right,
following the indication given in the top line of the table. The numbers of bits to the left of 9 are read placing 1 before the digit
indicated. The “Volt” column shows the value in millivolts of the respective analog inputs.The OUTPUT table is not normally
used.

10.2.7 A.T. FUNCTION
The A.T. function offers the convenience of displaying simultaneously:
• analog outputs of the DAB1 board
• digital countings of the DAB1 board
• digital input/output signals of a DRT module

Operating procedures are similar to those described in the corresponding paragraphs.The A.T. page is particularly useful
during installation, for example to check the general functioning of an axis.
To display a different DRTX board, position the cursor on the address and press the space bar until the address of the board
required is shown.

FIDIA MDO1384 10-7

10.2.8 MFB1 PUSHBUTTON FUNCTION
This displays a diagram of the standard pushbutton panel, connected to MFB1 board by means of “MFB DIGITAL” connectors.
Each pushbutton is represented by a rectangle containing two characters:
• The * character (asterisk) indicates whether or not the CNC controls switching on the lamp. If the asterisk is lit, but the
pushbutton is not, it means that either the signal is not reaching the pushbutton or that the lamp is burnt out.
• The T or _ (underscore) character indicates whether or not the CNC has detected a pushbutton pressed situation. T means
that the input bit is at low level, _ indicates that it is at high level.If the character T appears when the pushbutton is pressed,
it means that the signal is not reaching the CNC or that the pushbutton is not functioning.

The horizontal CLEAR LAMPS soft key is used for resetting all the output bits that control the lamps.
The percentage read by the CNC is displayed for each potentiometer. If operating properly, the percentage read will
correspond to the position of the potentiometer.

FIDIA MDO1384 10-13

10.3 CHECKING DIGITAL INPUT/OUTPUT SIGNAL LOGICS
The check sequence applies to standard FIDIA controls (i.e. not modified by the AUCOL option). In the event of the bits not
corresponding to this configuration, the manufacturer must set up a sequence of equivalent checks.
Please refer to the C_GEN program listing or to the Interfacing Manual for a precise definition of the signals and pinout.

10.3.1 CHECKING THE MANUAL/AUTOMATIC LOGIC

Check that the ENOUT signals of the DRT board on which the UDCMA signal is located, is at level 1 (Enabling Automatic
Mode). With the electrical cabinet powered on:
• The ID24C bit (indicating the presence of 24Vdc in the electrical cabinet) must go to 1.
• The IDHLD bit (Feed Hold) must be at 1.

With UDCMA at 1, the manual/automatic circuit should function and therefore the ENOUT signals of the DRT boards must go
to 1.

10.3.2 CHECKING AXIS CONTROL SIGNALS

With the machine tool axes position towards the centre of their travel, the IDFP* and IDFN* bits (positive and negative limit
switch) must be at 1. When the relevant microswitches are pressed, they should go to 0.
When the microswitches for the absolute zero search procedure are pressed, the relevant IDMZ* bits (axis zero microswitch)
must go to 1.
By setting the drive enables to 1 (UDSA* signals), the axis ready responses should be received (IDA*P signals at 1) when the
axes are effectively ready to be moved with a reference signal.
Measure the waiting time for the IDA*P response for each axis.
Also check that the remaining digital signals for the machine tool axes are used correctly.
IDTM* axis mounted
IDRBL* axis locked request
IDPFC prelimit switch
UDCNON CNC in execution
UDLPLP CNC in automatic copying

10.3.3 CHECKING SPINDLE SIGNALS

Set the spindle drive enables to 1 (UDSMO and UDSMA for the two directions of rotation) and check that the spindle drive is
ready for rotation.
Set the range change control signals (UDIG*) to 1 and check that the (IDG*I) responses are received once the range change is
completed. If necessary, perform the range change with the spindle in rotation and check the correct value of the analog
reference for the range change. Make a note of the value (to be entered later in the SP1RESCGA parameter).
Set the coolant control signal (UDCIR) to 1 and check that the coolant pump is activated.
Check that the remaining generalpurpose digital signals are used correctly (IDIRM, IDMAP, UDG00, UDG84, UDCSC,
UDAMP).“

MAINT” parameters: SP1RTM, SP1CGTM

10.3.4 CHECKING SIGNALS FOR LAMPS AND PUSHBUTTONS

Now check that the pushbutton panel signals are functioning correctly on the boards. By setting the digital outputs to 1, the
relevant lamps should light up; and by pressing the pushbuttons, the relevant digital input signals should be received.
The PUSHBUTTON function present in the test programm, allows the user to perform these checks in a easy and fast way.

10.4 CHECKING ANALOG REFERENCE SIGNALS

In order to perform the following checks, enter the DAB ANALOG page of the test program.
Check that by enabling the machine tool axis drives and giving a reference signal of 0 Volts via the test, the reference at the
output of the board is at 0 Volts.
At this point, check that the machine tool axes are not moving and if necessary, adjust the offset potentiometers of the drive.

10.5 CHECKING AXIS DIRECTION AND COUNTING

The following section refers to axes controlled by analog drives only. Checks for axes controlled by digital drives are performed
later (see Software Installation Manual). In order to perform the following checks, enter the A.T. page of the TEST program.
Check that when a small positive reference signal (1V for example) is given on the DAB board to the drives, the machine tool
axes move in the positive direction as shown in the diagrams below. If the movement direction does not correspond, invert the
feed loop of the drives (motor, tachogenerator). Single out the type of movement of the machine axes. If the tool moves, the
axes directions are represented with plain lines. Otherwise the tool is fixed, and the table moves: axes directions are shown
with dashed lines.

 Designation of CNC machine tool axes in accordance with EIA 267 standards

The following Figure shows two typical examples of milling machine axes.

Designation of CNC machine tool axes in accordance with EIA 267 standards

After setting the correct direction, the counting should be checked: a positive (negative) movement must correspond to a
positive (negative) counting.

FIDIA MDO1384 10-15

If the counting for an axis is discordant, switch the UA1* counting signal with UA2*, and the /UA1* signal with the /UA2* signal.

10.6 DISPLAYING I/O SIGNALS - BOARDS

The execution of the TEST program is not possible while the CNC is working.
Signals and other data relating to the interface boards between the FIDIA CNC and the machine tool are displayed on special
pages in the SERVICE area.
Procedure:
• Press the SERVICE soft key.
• Press the SERVICE I/O soft key.
• Select the board required. The page relating to the selected board is opened.

The displays are similar to those on the corresponding pages of the test program (TSTC1).
The main difference is that the test program pages (TSTC1) display existing boards only, while the MAINT I/O pages show all
possible boards including those that are not physically present.
The user can easily identify displays relating to boards that are not present since their ADDRESS field (address of board in
octal) is zero.

10.7 DEBUG
While the CNC is in operation it is possible to display and modify the values of the following variables:
• CNC and AUCOL digital and analog I/O signals;
• AUCOL bits and memory areas.

Display and debugging are performed on a debugging page that can be accessed by the following procedure:
• Open access to the SERVICE area. Logon using as a Password the number resulting from the sum of the year + month +
day (or another Password of the same level, if defined).
• Press the AUCOL “DEBUG” vertical soft key
• A dialogue window appears.

Select the AUCOL symbols file to be debugged and click on the OPEN pushbutton.
The symbols file is generated automatically during compilation of the AUCOL program.
It has the name of the AUCOL program and the extension .DBG.

Choosing the .DBG extension file a context enabling to execute the complete debug of the AUCOL is entered.
Debug use is explained in the relevant Help-on-line, accessible by pressing F1 key.
