hardware and controller.

Renishaw has no control over the exact program configuration of the controller with which
the software is to be used, nor of the mechanical layout of the machine tool. Therefore, it
is the responsibility of the person putting the software into operation to:

 ensure that all machine tool safety guards are in position and are correctly working
before commencement of operation;

 ensure that any manual overrides are disabled before commencement of operation;

 verify that the program steps invoked by this software are compatible with the
controller for which they are intended;

 ensure that any moves which the machine tool will be instructed to make under
program control would not cause the machine tool to inflict damage upon itself or
upon any person in the vicinity;

 be thoroughly familiar with the machine tool and its controller, understand the
operation of work co-ordinate systems, tool offsets, program communication
(uploading and downloading) and the location of all emergency stop switches.

IMPORTANT: This software makes use of controller variables in its operation. During its
execution, adjustment of these variables, including those listed within this manual, or of
tool offsets and work offsets, may lead to malfunction.

2 Introduction

Introduction

CAUTION: Changes to the TAB_*.REN files, or to any other file in the machine tool
program logic control (TNC and PLC) area, can have a detrimental effect on the
functioning of the machine tool and can be dangerous. This guide is intended for use by
equipment manufacturers only, who are qualified and familiar with the operation of the
machine tool. A back-up of the CNC should be made before starting the software
installation.

This guide assumes a working knowledge of the Heidenhain TNC 620/640 controllers,
including access to the PLC area and TNCremo (version 2 or later) PC packages. The
NCTS software installation requires the PC and the machine tool controller to be
connected via TNCremo. The software is installed by moving files from the PC onto the
controller using the ‘drag-and-drop’ method.

System requirements
PC system requirements
 486-based PC, or better.

 Windows 95 operating system, or later.

 VGA display, or better.

 Minimum 16 MB of RAM.

 TNCremoNT.exe (free download from the Heidenhain website).

 Ethernet port.

Controller requirements
 Option #17 (probing).

 One input into the controller.

 Heidenhain NC software 340 564-02, or later.

 Heidenhain monitor (for screen size and type, see Note 1 on the next page).

NOTES:

1. The help graphics supplied with this package are only suitable for the following
monitor:

• Visual display unit BF 150 15.1-inch colour flat panel display (1024 × 768 pixels).
The following monitor is NOT currently supported:

• Visual display unit BF 120 10.4-inch colour flat panel display (640 × 480 pixels).

2. The RS232 port data transfer rate will be too slow for uploading the large help
graphics supplied with this software. Therefore, it is recommended that the data
transfer is made via the Ethernet connection (for settings, see the Heidenhain
manual).

• You can connect the Ethernet card in your TNC to your network through the
RJ45 connection (X26, for a 100BaseTx or 10BaseT), using a twisted pair
cable.

• If you connect the TNC directly with a PC, you must use a crossed cable.
For further details, see “Ethernet interface/13.2 Pin Layout and Connecting Cable for
the Data Interfaces” in the Heidenhain user’s manual.

3. If your controller supports USB, this may be used for uploading the software.

Controller tool table requirements

The following tool table elements must be set up for use with the Renishaw cycles.

Input 0 No display.
Inputs 1 to 99 Represent the position (L to R) in the tool table.

NOTE: When the Heidenhain ‘Replacement tool’ option is to be used, the optional tool
table element RT is also required.

Configuring a PC for USB network interface connection

It is beyond the scope of this manual to provide a comprehensive description of how to
connect and set up a PC for Ethernet use via a USB network interface, since there are
many possibilities depending on the PC hardware/software combination. However, the
following example is provided as a guide.

You should also refer to the Heidenhain documentation (see also “12.5 Ethernet
interface” in the Heidenhain user’s manual for PC compatibility and networking software).

If your PC does not already have suitable network software, for Windows operating
systems Heidenhain recommends the network software CIMCO NFS server which you
can order separately or together with the Ethernet card for the TNC.

TNC, use the grey bar halfway down the screen to select the TNC:\TABLE folder.

NOTE: Before uploading the set-up table, if you wish to have a German-language set-up
table, you must find the file TAB_1_de.REN in the folder REN_INSTAL\TABLE and
rename it TAB_1.REN.

Drag and drop the TAB_1.REN file from the PC to the TNC:\TABLE folder.

Set the PC to the REN_INSTAL\REN_TNC folder and the TNC to the TNC:\ folder. Drag
and drop the REN_TNC folder from the PC to the TNC:\ folder.

NOTE: The software is now loaded. Please refer to the “Editing the PLC configuration
files” section. The controller needs to be powered down and then powered up again to
activate the software.

When the controller is rebooting, if it stops and asks for a key code, this indicates that
there are errors in the config files. Key in 95148 to show the error. This will then allow the
use of TNCremo to upload the back-up files and allow the files to be corrected. If the
software is not to be loaded, reload the back-up of the configfiles.cfg and oem.cfg
files.

Using the Renishaw set-up tables (files TAB_*.REN)

One Renishaw set-up table is provided – TAB_1.REN. If extra tables are required, please
see the section below “Adding extra tables”.

During installation of the NC tool setting system, the Renishaw set-up table parameters
will have been completed to define the specific system setting appropriate to the machine
tool.

Under instruction from the equipment supplier, it may be necessary to alter some of these
parameters for specific tasks in order to optimise system performance, for example,
altering the maximum and minimum tool lengths, sample size, scatter tolerance and the
first back-off factor.

CAUTION: Changing a *.REN file or any other file in that area can have a detrimental
effect on the machine tool’s function and can be dangerous. Always consult the
equipment supplier before making changes.

Renishaw set-up table (TAB_*.REN)

No. Name Explanation

0 SOFTWARE VERSION Renishaw software version number.

For reference only.
1 LA AXIS BEAM POSITION 1 The machine tool axis positions (REF) of the measuring point
2 RA AXIS BEAM POSITION 1 along the laser beam. This is defined during installation.
3 SP AXIS BEAM POSITION 1 La = laser axis
Ra = radial measuring axis
Sp = spindle axis
Usually this point is equidistant from the laser transmitter and
receiver units. The preliminary values are captured by the
alignment cycles (500 or 501). They are then used and accurately
updated by the calibration cycle (502).
Automatic – do not edit manually.
4 BEAM RADIUS 1 The effective radius of the laser beam.
This is captured during the calibration cycle (502).
Automatic – do not edit manually.

Renishaw set-up table (TAB_*.REN)

No. Name Explanation

5 X112 SWITCHING If the tool will not retract out of the beam, set this to 1.
6 SINGLE SIDED To maximise measurement accuracy and repeatability, calibration
CALIBRATION on both sides of the laser beam is recommended as default.
0 = NO, 1 = YES If this is not possible, due to a lack of access for the calibration
tool to both sides of the beam, calibration from the Radial
measuring direction is possible (see item 7).
Default = 0
7 RADIAL MEASURING The direction in which radial measuring moves are made.
DIRECTION 1 = probing in positive axis direction
−1 = probing in negative axis direction
0 = probing in both directions (both sides of the beam)
Default = 0
8 SIGNAL PULSE TIME The hardware signal pulse time (in ms).
This is the time that any trigger signal is held on, and is dependent
on the hardware set-up. This may be ascertained by the LED flash
sequence on power-up (for details, see the installation guide).
Default = 100 ms
Compulsory – enter before operation.
9 MAXIMUM TOOL LENGTH The maximum and minimum tooling dimensions (see item 14 –
10 MINIMUM TOOL LENGTH Approach method).
11 MAXIMUM RADIUS These values define the rapid approach move positions and
therefore have an effect on cycle time. They are usually
dependent on the machine tool’s architecture and intended use.
The minimum tool length is usually limited by the relative position
of the laser beam and the tool holder.
Compulsory – enter before operation.
12 INITIAL SAFE POSITION The spindle axis (Sp) safe position from which all cycles begin
(excluding the alignment cycles 500 and 501). This is normally set
to the tool change position.

TIP: To find this position, make a tool change so that the spindle
is at the correct height (or move the tool to a safe height position).
Change the display registers to REF values then enter the
position displayed.

Compulsory – enter before operation.

13 APPROACH DISTANCE The distance from the beam at which the reduced feedrate
probing moves begin (see item 14 – Approach method).
Default = 10 mm
Compulsory – enter before operation.
14 APPROACH METHOD The sequence of operation for measuring cycles. Two approach
0 = TT, 1 = RENISHAW methods are available:
 Rapid approach, using tool data (0)
 Search approach, without use of tool data (1)
0 = The tool moves rapidly to the Approach distance (default
10 mm) from the beam, based on the approximate tool length and
radius data (L, R) that has been entered into the active tool table.
From there, the tool moves into the beam and is triggered.
1 = The system sets tools without any prior tool measurement, i.e.
no tool length or radius data is required to be present in the tool
table. The tool moves rapidly to the Maximum tool length position.
From there, the tool moves into the beam and is triggered. This
method offers the flexibility of length and radius setting without the
need for approximate tool data in the tool table. However, it incurs
an increased cycle time compared with the alternative method.
Default = 1
Compulsory – enter before operation.
15 NUMBER OF FINAL The sample size of final probing touches.
TOUCHES – SAMPLE SIZE This number of final touches is made and their difference is
compared with the Scatter tolerance. If outside the tolerance, the
measurements are repeated. The number of retries that are made
is twice this value.
Default = 2
Compulsory – enter before operation.
16 SCATTER TOLERANCE The scatter tolerance of probing results.
If results from the set number of measuring touches fall outside
this value, the measuring moves are repeated, up to the number
of retries (twice the number of final touches).
Default = 0.01 mm
Compulsory – enter before operation.
17 MEASUREMENT The feed-per-revolution during measurement moves.
RESOLUTION Increasing this value decreases measurement accuracy, but
increases the speed at which measurements are made.
Default = 0.002 mm
Compulsory – enter before operation.

18 FIRST BACK OFF FACTOR The distance by which the tool is backed off after the first trigger,
before returning for the second trigger.
Default = 1.5 mm
Compulsory – enter before operation.
19 SECOND BACK OFF The distance by which the tool is backed off after the second
FACTOR trigger move.
This value is also used for all subsequent probing moves – the
number of which is defined by the Number of final touches (see
item 15).
Default = 0.2 mm
Compulsory – enter before operation.
20 REPOSITIONING FEED The feedrate at which movements between length measurement
RATE and radius measurement positions are made.
Default = 10000 mm/min
Compulsory – enter before operation.
21 FEED RATE TO MAXIMUM The feedrate at which the tool is positioned to the Maximum tool
TOOL POSITION length prior to a probing move.
Default = 5000 mm/min
Compulsory – enter before operation.
22 FEED RATE TO MINIMUM The feedrate at which the tool is moved towards the Minimum tool
TOOL POSITION length and into the beam. A trigger would be expected during this
move.
Default = 2000 mm/min
Compulsory – enter before operation.
23 LINE NO. OF FIRST REN Leave this set to 0 to use the print-to-screen method for error
ERROR messages.
Default = 0
24 TOOL CHECK ALARM? The cycles with tool checking options or broken tool detection
0 = NO, 1 = YES measure a tool and compare the result against a given tolerance.
If outside this tolerance, the tool is classified as broken and the
Tool Lock (TL) flag is applied to that tool in the active tool table.
With TOOL CHECK ALARM? = 1, the machine tool stops
automatically with an alarm.
However, if the machine tool is required to continue operating and
call a sister tool (where defined), setting TOOL CHECK ALARM?
= 0 sets the (TL) flag only, without stopping the machine tool.
Default = 1
Compulsory – enter before operation.

Where only the standard cycles are to be used, requiring the
minimum of installation wiring, enter 0 (limited).
Where a full wiring installation has been carried out, including
M-code configuration, enter 1 (All).
It is important that this parameter is set correctly, as it prevents
the extended cycles, which are dependent on additional wiring,
from being run inappropriately.

Defining the M-codes for latch mode (M-code 2)

When using the M-code method of controlling latch mode, it is also necessary to edit two
programs supplied (Actlatch.h and Dislatch.h).

These will be found either on the software media or on the TNC (machine tool controller)
in the PLC:\OEMCYC\TREE*\RENISHAW\NC directory when loaded onto the TNC. Use
TNCremo to download these files to make the edits off the machine tool and then reload
them.

Defining the MT_start.h and MT_end.h programs

NOTE: These files are supplied as empty files and really have no function unless
customisation code has been added to them by either the machine tool builder or the
commissioning engineer.

The programs will automatically be installed in the controller in the correct place by the
installation wizard. Otherwise you can use TNCremo.

They will be found on the software media in the CYCLE_PROGRAMS directory and must be
loaded into the PLC:\OEMCYC\TREE*\RENISHAW\NC directory.

To edit these files, use TNCremo to download the files and subsequently reload them
after making the changes. Custom code can be added for things like additional
positioning moves or M-codes before the core cycles run. An example of this is when
using a tilting head – you may want to first send the Z axis to a safe position before
indexing the head to the correct position.

Parameter Q277 is always set to the active program number. For example, if the
alignment cycle is running, then Q277 will be set to 501. This can then be used in the MT
start or MT_end programs to jump over the custom code for cycle 501 when other cycles
are running.

Two calibration/measuring positions

The software can support two setting positions on the same laser beam or two NC units
on the same machine tool. A flag Q329 = 0 is set at the top of all cycles. If this remains
set to Q329 = 0, then position 1 is always used (this is the default normal situation).
However, if this is set to Q329 = 1, position 2 will be used when a cycle is run. It is
therefore possible to control two setting positions by entering custom code in the
MT_start.h program.

Typically, the machine tool builder may provide a marker flag that specifies which setting
position (1 or 2) to use. Alternatively, it might be OK to read an axis position to decide
which setting position to use.

Examples of setting MT_start.h programs below:

1. Using markers
BEGIN PGM MT_start MM
FN 18: SYSREAD Q90 = ID2000 NR10 IDXxxxx ; marker number
FN 9: IF +Q90 EQU +0 GOTO LBL 1
Q329 = 1
LBL 1
END PGM MT_start MM

2. Using machine tool position

BEGIN PGM MT_start MM
FN 18: SYSREAD Q90 = ID240 NR1 IDX1; read X axis position
; if Q90 < 1000 use position 1, else use position 2
FN 12: IF +Q90 LT 1000 GOTO LBL 1
Q329 = 1; use setting position 2
LBL 1
END PGM MT_start MM

Publication No. H-2000-6681

 Simple system checks (for installations that include extended cycles) 25

3. Using the machine tool position for a broken tool detection cycle only
BEGIN PGM MT_start MM
FN 9 IF +Q277 EQ 506 GOTO LBL1; check if broken tool cycle
FN 9 IF +Q277 EQ 507 GOTO LBL1; check if broken tool cycle
FN 9 IF +Q277 EQ 501 GOTO LBL1; check if align cycle
FN 9 IF +Q277 EQ 502 GOTO LBL1; check if calibration cycle
FN 9 IF +0 EQ +0 GOTO LBL2
LBL 1
FN 18: SYSREAD Q90 = ID240 NR1 IDX1; read X axis position
;
; if Q90 < 1000 use position 1, else use position 2
FN 12: IF +Q90 LT 1000 GOTO LBL 1
Q329 = 1; use setting position 2
LBL 2
END PGM MT_start MM

After the MT_start program has been changed, upload it back to the PLC. Now run the
alignment and calibration cycles for the first position, then align and calibrate in the
second position. Should the system be moved or a new setting position be required in the
future, the above procedure must be repeated.

Simple system checks (for installations that include extended

cycles)
Before running any cycles, perform the following checks. The results will show if
hardware integration has been completed correctly.

Checking the status of the input signal to the controller

This check is performed on the Inputs diagnostics page (available only when the
extended cycles are to be used). The input signal should be 0 when the laser beam is
clear and 1 when the beam is broken.

1. To view the Inputs diagnostics page, enter the PROGRAMMING AND EDITING
area.

2. Press the MOD key.

3. At the Password screen, enter the Heidenhain PLC password.

4. When the password is accepted, select the TABLE soft key, then the M/I/O/T/C soft
key from the bottom of the screen. Now press Input.

5. Press GOTO and enter the input number (address) that is used for the extended
cycles. This is specified in item 25 – Input Status address in the Renishaw set-up
table (TAB_*.REN).

2. Select the M-code that is assigned to activate latch, i.e. program Actlatch.h (see
“Defining the M-codes for latch mode (M-code 2)”).
When the laser beam is clear of obstruction, the input status (as described above)
should be 0.
After the beam is broken, the input status should change to 1 and stay at 1 when
the beam is cleared (i.e. latched).

3. Select the M-code that is used to switch latch off, i.e. program Dislatch.h (see
“Defining the M-codes for latch mode (M-code 2)”.
The input status should return to 0.

PLC marker method

1. Enter MDI mode.

2. Type in the following test code to enable the marker and execute to the M0:

FN 17: SYSWRITE ID2000 NR10 IDXxxxx = +1 (where xxxx is the marker number)
M0

When the laser beam is clear of obstruction, the input status (as described above)
should be 0.
After the beam is broken, the input status should change to 1 and stay at 1 when
the beam is cleared (i.e. latched).

3. Type in the following test code to reset the marker and execute to the M0:

FN 17: SYSWRITE ID2000 NR10 IDXxxxx = +0 (where xxxx is the marker number)
M0

The input status should return to 0.

When the laser beam is clear of obstruction, the input status (as described above)
should be 0.
After the beam is broken, the input status should change to 1 and stay at 1 when
the beam is cleared (i.e. latched).

3. Type in the following test code to reset the marker and execute to the M0:

FN 17: SYSWRITE ID2000 NR10 IDXxxxx = +0 (where xxxx is the marker number)
M0

The input status should return to 0.

Fault diagnosis

NOTE: Custom software packages may use a different system test program. These
programs may require editing to suit the system set-up.

A sample system test program is supplied with this software and described below. It is
recommended that it is copied into a suitable sub-directory on the controller.

Example: TNC:\REN_TNC\SYS_TEST.h

If the NCTS system and software do not operate correctly after the installation is
completed, as described in this publication, it is suggested that a test program is used to
test the major software functions before running the cycles.

28 Fault diagnosis

Programming FN17 commands

The test program uses the FN 17: SYSWRITE command to write instructions to the
controller’s PLC. This function is not normally available for selection from the soft key
menu and must be activated by entering a password.

Do this as follows:

1. Enter the PROGRAMMING AND EDITING area.

2. Press the MOD key.

3. At the Password screen, enter the applicable Heidenhain password to activate

FN17 then press ENTER (555343).

4. Select FN17 via a soft key. This may be reached by pressing Q on the numerical
keypad then selecting the DIVERSE FUNCTIONS soft key.

Running the test program

1. Call the calibration tool into the spindle using a TOOL CALL command. Remember
to include an S input to specify a spindle speed.

2. Use the JOG buttons to position the tip of the calibration tool approximately 10 mm
above the laser beam.

3. Turn the controller to RUN FULL SEQUENCE mode and select the test program.

4. Press the cycle start button.

5. During the test program, the spindle should move down 20 mm. If the calibration
tool has been positioned correctly, it should block the laser beam during this move.

6. After the beam is blocked, the machine tool should stop moving.
