 2. COMMON INFORMATION

(2) Card installation sequence

There are three types of DI/DO cards: DIO-A, DIO-B, and DIO-D listed in
2-1-3. The installation sequence of the cards is listed below:

M31O The first card is fixed to DIO-A. The second card is selected
among DIO-A, DIO-B, and DIO-D.

M320M, 320L The first card is fixed to DIO-A. The second and third cards are
selected among DIO-A, DIO-B, and DIO-D.

M330M, 330HM, The first and second cards are fixed to DIO-A and DIO-B. The
third and later cards are selected among DIO-A, DIO-B, and DIO-D.

Note: For standard PLC, the first card is fixed to DIO-A and the second and
third cards are fixed to DIO-B.

2-1-2 DI/Do Cards and Corresponding Devices

(1) Correspondence between input/output devices and connection connectors

On a DI/DO card, XRCICIwhich is input to PLC from the machine is input

through C=~- ❑ and YOOO which is output to the machine from PLC is output
through C~D- ❑ .
❑ UJ varies depending on the DI/DO card to be used. See 2-1-3 for details.

(2) Correspondence between card installation locations and input/output devices

Although the number of input/output points varies depending on the card

type, 64 input points and 64 output points are assigned per card regardless
of the card type in the M300 series. Thus, on a card which contains 48
input points, devices corresponding to 49th to 64th points are not used.

Likewise, AC output devices corresponding to the first 16 points are only

used.

 2. COMMON INFORMATION

(1) Caution when VDE or non VDE is set

Although M300 seriew input signal common is +24 V (VDE) as standard, ground
common (non VDE) can also be selected.

If ground common (non VDE) iS set, the logic of 16 DIO-D card points becomes
opposite to that when +24 V common is set. This means that 1 and O are
opposite to each other when viewed on a sequence program.

Example:

At emergency stop, M300 series output circuits other than 47, 15, 32, 48,
or 16 in the CFD13 of the first DIO card MC301 are reset for safety as
standard. (At emergency stop, output circuits should be reset as much as
possible.)

Note that if other output circuits than the five points mentioned above are
also used without reset at emergency stop, the output ciruits are not
cleared by hardware when emergency stop is applied.

Note: When user PLC is stopped, CNC is also placed in emergency stop state,
but the signals output to the output ciruits which are not reset at
emergency stop remain on. The point to be particularly noted is the
brake signal to prevent falling of the top and bottom axes. Since
the servo is turned off with the brake released, the axes are in
danger of falling. To stop user PLC, be sure to use another means
for emergency stop after applying the brakes.

FUNCTION:

This signal indicates that the drive sYstem of the n-th axis is
ready for operation.

OPERATION:

The signal turns on when,

(1) the power supply of the control system is turned on and the
diagnosis on the servo system has been completed successfully.

(2) servo alarm, if occurs, has been reset,

(3) emergency stop has been reset, and

(4) servo “OFF” signal is not inpl~t.

The signal turns off when

(1) servo alarm occurs, or

(2) emergency stop is commanded, or

(3) “OFF” signal is input.

FUNCTION:

This signal indicates that motion command is given to the drive

system of specified n-th axis.

OPERATION:

This signal turns on and off as follows:

(1) Automatic operation

The signal is on while “feed axis select” signal (+Jn and

-Jn) is on.

(2) Manual operation

o1 For JOG mode

The signal is on while “feed axis select” signal (+J1 to

+6, and -J1 to -J6) is on.

o2 For HANDLE mode

When “handle axis No.” signal (HS1l to 116) and “handle

axis valid” signal (HSIS)have been selected, the axis sel-
ect output signal for the axis specified by the handle
axis No. signal is on.

o3 For INCREMENTAL mode

The signal turns on when “feed axis select” signal tAUYIS

on, and turns off when the specified motion is completed.

o4 For MANUAL RANDOM FEED mode

The signal turns on when “strobe” signal (CXS8) turns on,

and turns “off when the specified motion is completed.

Even when “stop” signal (CXS7) is turned off (0) during

motion, the axis select output signal remains on.

o5 For REFERENCE POINT RETURN mode

The signal is on while “feed axis select” signal (+Jn and

-Jn) is on.

- 184 -
 After “reference point proximity detect” signal is output
and the motion speed changes to approach (creeping) speed,
however, the axis select output signal remains on until
the motion stops at the reference point, even when “feed
axis select” signal turns off.

(3) Other conditions

o1 The signal can turn on even during machine lock (Z-axis is

in cancellation). However, it does not turn on during
machine lock in manual operation mode.

o2 The signal remains on even when motion stops due to feed-

rate override set at zero %, manual control feedrate set
at zeromm/min, or zero inch/rein.

o3 Interlock does not affect status of this signal (the sig-

nal remains on, or turns on).

o4 Servo “OFF” signal does not affect status of this signal.

o5 The signal cannot be turned on by G04 and G92.

o6 The signal turns off with NC RESET 1 or 2, or EMERGENCY

STOP .

FUNCTION:

This signal indicates that the specified axial motion is in plus

(+) direction.

OPERATION:

The signal turns on when

(1) the specified axial component starts moving in the plus direc-
tion.

The signal turns off when

(2) the specified axial component stops moving or moves

in the minus direction.

FUNCTION:

This signal indicates that the axial component of the n-th axis
is on the 1st reference point.

OPRATION:

The signal turns on when,

(1) 1st reference point in-position is achieved in REFERENCE PO-

INT RETURN mode during manual operation, or by G28 command
during automatic operation.

If 1st reference point in-position is achieved in other opera-

tion mode, or by other command, the signal does not turn on.

The signal turns off when,

(1) the axial component in position is relocated from the lstre-

ference point by motion command or manual operation (machine
handwheel, for example), or

(2) EMERGENCY STOP signal is input or SERVO ALARM occurs, causing

stop to the machine.

FUNCTION:

This signal informs that a special miscellaneous function (MOO) is

selected and commanded.

When a special M function is specified, normal miscellaneous func-

tion strobe signal and M code data are output.
M single outputs include MO1, M02 and M30.

OPERATION:

When MOO, MO1, M02 or M30 is specified during AUTO operation (MEM-
ORY, MDI or TAPE), or by manually set numerical command, this
signal turns on. The signal turns off if M function complete
signal, reset signal or reset & rewind signal is given.

.

If motion command and/or dwell is present in the same block, the

signal turns on after completion of dwell.

However, the signal is not output if M function complete signal

turns on before completion of motion command or dwell.

Generally, each M code is used for the following purpose:

MOO ..... Program stop

MO1 ..... Optional stop
M02, M30 .... Program end

o Operation on user PLC side

(1) For MOO

When MOO is input, single block signal (SBK) is turned on

- 235 -
 and M function complete signal (Fin 1 or Fin 2) is sent
back.

(2) For MO1

When MO1 is input, optional stop switch setting (ON or OFF)

is checked. If the setting is “ON”, single block signal

is turned on and M function complete signal is sent back,

like the case with MOO.

If the setting is “OFF”, M function complete signal is sent

back immediately.

(3) For M02, M30

When M02 or M30 is input, reset & rewind signal (RRW), or
reset 1 (RST1) or reset 2 (RST2) signal is sent back instead
of M function complete signal.

If M function complete (Finl, Fin2) signal is sent back,

“program end error” may occur.

FUNCTION:

This signal informs what gear stage is applied to the S command

specified in AUTO operation (MEMORY, TAPE or MDI), or by enter-
ing numerals in manual operation.

The user PLC uses this signal for gear shift.

OPERATION:

When S command is specified (in MEMORY, TAPE or MDI operation, or

range and the determined spindle speed range is output in terms
of gear stage with 2-bit code (GR1 and GR2).

FUNCTION:

This signal informs that specific external function (terminal de-

vice) must be started after completion of G81 positioning.

Therefore, this signal is used to perform specific operation, such

as drilling and punching.

Whether G81 command is used for eXternal function, or used as can.

ned cycle depends on option (with or without external fmction) .

When the system is equipped with external function, G81 cannot be

used for canned cycle.

OPERATION:

The signal turns on when

(1) G81 positioning is completed and “in-position” signal is

output .

The signal turns off when

(1) M function complete signal (FIN1 or FIN2) is sent back, or

(2) reset

User PLC handles the external function strobe signal (EF) and M
function complete 1, 2 signals (FIN1, FIN2), like the case with
miscellaneous function strobe signal (MFn), as shown in the below
timing chart.

EF(ext. function command)

Although motion command complete signal (DEN) is also output, it

is not necessary to use that signal because external function
strobe signal (EF) itself bears the conditions equivalent to
those of DEN.

FUNCTION:

Spindle speed reference signal specified in automatic operation

(MEMORY, MDI or TAPE) or by manual numerical data input is input.

Spindle speed reference output from the CNC can be taken in terms
of BCD code or binary code (can be selected by machine manufactur-
er’s parameter).

Since spindle speed reference is a data pertinent to analog signal

processing, usually binary code is selected.

Under the S analog mode, the data can be monitored in the “S

display” on the command value screen. (Under other modes, the “S
display” displays the contents of file registers R28 and R29.)

OPERATION:

Set spindle speed reference is renewed when

(1) “S**” is specified in automatic operation (MEMORY, MDI or TAPE)

and M function complete 1 or 2 signal (FIN 1 or FIN 2) or gear
shift complete signal (GFIN) is sent back to the CNC, or

(2) “S**” is specified by manual numerical command input and M

function complete 1 or 2signal (FIN1 or FIN2) or gear shift
complete signal (GFIN) is sent back to the CNC.

Note: Data cannot be cleared by “reset” or “emergency stop!! (eX-

FUNCTION:

These signals provide input signal interface required when an ad-

ditional (2nd) operation board interface card is used in a system
using DI/DO type operation board.

Generally, these signals are to be input to “bit-based arithmetic

operation area (X***). They, however, are input to file registers
(R).

OPERATION:

The signals are read together with other input signals at start of
PLC main processing (medium speed).
Since these signals are once read by the CNC and then by the ?LC,
data updating delays somewhat as compared with DI signals of normal
DI/DO cards.

FUNCTION:

When motion of a specific axis (n-th axis) in minus direction

activates interlock function, only that axis motion of machine
can be decelerated and stopped immediately during manual opera-
tion.

OPERATION :

When this signal turns off for a specific axis in motion in

the minus direction under manual operation mode, motion of
the axis decelerates and stops with MO1 operation error code
“0004” displayed. With this signal set off from the
beginning, the system completes calculation for axis motion
but makes it remain stopped with the same operation error
code displayed. In either case, setting the signal on
resumes or starts axis motion.

RELATED SIGNALS:

Manual interlock, +n-th axis

Auto interlock, +/-n-th axis

CAUTION:

(1) All interlock signals are for B contact.

(2) Since interlock signal “Y*~” is automatically set to “l!!

(on) when the power is turned on, no interlock
programming is required for an axis that are not to be
used.

FUNCTION:

During automatic operation, current position can be changed

without actual machine motion to check program.

OPERATION:
In the automatic operation (MEMORY, MDI or TAPE), when this
signal is on, the current position can be changed on a
specific axis (for which the signal is on) without actual
machine motion. If the signal turns on in the middle of a
block, block termination occurs after the completion of that
block, and then the machine lock will be valid for the
following blocks.

RELATED SIGNAL:

Manual machine lock, n-th axis

CAUTION:

(1) If auto machine lock signal changes during automatic

operation, block stop occurs after completion of the
block in execution.

(2) Setting the third axis of this signal to ON provides the

Z-AXIS CANCEL function which was available in
conventional systems with a machining center.

FUNCTION:

REFERENCE POINT RETURN mode is selected.

“Reference point return” is that axis motion component (tool, table,

etc.) is returned to the position previously determined for in-
dividual machine.

OPERATION:

(1) Reference point return occurs when feed axis select (+J1 - +J6,
-J1 - -J6) signal is turned on after REFERENCE POINT RETURN
mode signal (ZRN) is turned on in manual operation.

o “Dog type” reference point return occurs for the first time
after the power of control system is turned on.

For 2nd and thereafter reference point return, either “dog

type” or “high speed type” can be selected by setting a para-
meter.

(2) There are two patterns of reference point return.

0 Direction of approach mction, which occurs after limit switch

is actuated by the proximity point dog in bidirectional
axis motion, is set by a parameter..

~------

0 Pattern where proximity point dog is located close to the

reference point

~ ~ Reference point
I Doe

- 322 -
 If the axis motion component is away from the proximity
point dog when deceleration is completed, it moves back
in the reverse direction in the approach speed until it
detects the proximity point dog again. When the proximity
dog is detected, the component moves toward the reference
point and gets in-position as the normal return.

Notes: 1. After speed is decelerated to approach speed, the

approach motion continues, even after feed axis
Select signal (+J1 - +J6, -J1 - -J6) is turned off,
until the motion is stopped at the reference point.

Therefore, axis can be switched to other axis,

after speed is changed to approach speed, to term-
inate reference point return on other axis.

2. Speed (feearate) before it is decelerated to ap-

proach is “rapid traverse speed” when rapid tra-
verse signal (RT) is on, or “manual feedrate”
(+JV1 - *JV16) when rapid traverse signal (RT)
is off.

FUNCTION:

The CNC is reset and the machining program currently in execution

is headed in MEMGRY operation, and tape is rewound in TAPE opera-
tion (when tape reader with tape reel is used).

op~~TIoN:

When this signal (RRW) turns on,

(1) ongoing axis motion is decelerated and stopped,

(2) CNC is reset after axis motion stops.
In about 0.5 sec after CNC is reset, reset output signal (sta-
tus signal RST) turns on,

(3) at the same time as CNC is reset, rewind signal (RWD) turns
on.

o1 In MEMORY operation mode, the head of program in execution

is read (heading).

o2 In other operation mode (MDI or TAPE), the tape is rewound.

The tape is not rewound if the tape reader is in use for

background edit.

(4) while the signal (RRW) is on, automatic operation and manual
operation are impossible,

(5) G command modal is initialized,

FUNCTION:

The M300 series uses a Gear Shift Complete signal to perform

smooth control of spindle speed (S analog signal control). This
signal changes the spindle speed to the speed (S command)
specified in the machining program.

OPERATION:

To change the spindle speed to the speed specified by the S

command during automatic operation (memory, MDI, or tape), it is
needed to turn on the Gear Shift Complete (GFIN) , M Function
Complete 1 (FIN1), or M Function Complete 2 (FIN2) signal.

S command

Rising edge of GFIN,

FIN1, Or FIN2__

When using the Gear Shift Complete signal, the following two
conditions should be considered:

(1) Whether gear shift (gear change) is applicable (whether

there are two or more states of gear shift).

(2) Whether “up-to-speed” signal output from the spindle

controller is used for verification of spindle speed.

FUNCTION:

This status signal informs the CNC that specified miscellaneous

(M) function, spindle (S) function, tool (T) function or 2nd
miscellaneous function (A, B or C) is accomplished on the PLC
side.

OPERATION:

When the PLC verifies that one or more M, S, T and/or B function

has been specified, it performs that function(s) and, after tom-’
pletion of the function(s), sends back”M function complete 1“ sig-
nal (FIN.1)to the CNC.

When the CNC verifies that signal FIN1 turns on, it turns off
strobe signal of corresponding function.
The PLC checks that each strobe signal turns off, then
off FIN1.

With the signal FIN 1 turned off, the CNC proceeds to the next
block.

_QH-L M330HL I I

When suspended operation is resumed, tool or table can be located

to the position, where operation was stopped or suspended, in
manual operation to check direction of motion, or positiong.

“PROGRAM RESTAR”

When tool is found worn out or damaged during cutting in auto-

matic operation, or when machining is suspended and resumed
on the next day, operation Cm be restarted from the previousl-
y suspended position.
For details, refer to the instruction manual.

OPERATION:

(I) When program restart signal (SRN) is turned on after comple-

tion of program search and axis motion is tried in manual op-
eration mode to locate tool or table to the restart position,
operation error occurs if the direction of the motion is re-
verse. When the direction ef the motion is correct, the
motion stops automatically at the restart position.

When the tool or table is positioned correctiy, display “re-

maining distance for restart” and ~’restartposition” on the
CRT screen indicate zero and “RP” respectively.

FUNCTION:

When the CNC is ready for user macro interrupt, the progr~ be-
ing in execution can be interrupted, or other program can be ex-
ecuted after the former program has been executed, by turning
on macro interrupt signal (UIT).

OPERATION:

When macro interrupt (UIT) turns on within time interval

signal
starting with M96 command (Note 1) and ending with M97 com-
mand or reset, the program being in execution can be interrupted
for execution of other program.

Macro interrupt signal (UIT) becomes valid when

(1) MEMORY, TAPE or MDI is selected,

(2) automatic operation is selected (signal STL is on),

(3) other user macro is not being executed, and

(4) parameter “user macro interrupt valid” is selected.

When manual operation mode (JoG, STEP, HANDLE, etc.) is being sel-
ected, the signal (UIT) is invalid.

User macro interrupt signal (UIT) is accepted in “status trigger’1

method or “edge trigger” method, either one of which can be sel-
ected by parameter.

(1) Status trigger method

While user macro interrupt signal (UIT) is on, the signal can
be accepted.

When M96 is used to make acceptable user macro interrupt, the

inserted program is executed when the signal (UIT) turns on.

With the signal (UIT) kept turned on, inserted program can be
executed repeatedly.

- 352 -
(2) Edge trigger method
The signal (UIT) is accepted when its status changes from
.
“OFF” to “ON” (i.e., with rise edge of signal).

This method is advantageous when inserted program is execut-

ed only once.

COMMAND FORMAT :

FUNCTION:

F1-digit feedrate set in the CNC can be increased or decreased

by means of manual pulse generator.

When value following feedrate address “F” is of one digit, one of

eight feedrates previously set in the CNC (Fl - F8) is selected.

OPERATXQN:

(1) When F1-digit feedrate change valid signal (FID) is turned on

and feedrate is specified with programmed F1-digit command,
feedrate can be increased or decreqsed by turning the manual
pulse generator (handle).

(2) Feedrate increment or decrement per one graduation of the

manual pulse generator can be determiend from the following
formula:

F1 = ‘mKax

where, K: Factor (parameter set for determination of incre-

ment or decrement per one graduation of manual
pulse generator)

Fmax: Fl: -F4 maximum feedrate (FM1 parameter setting)

: F5: -F8 maximum feedrate (FM2 parsmeter setting)

Whether feedrate change is increment or decrement depends on

direction of rotation of the manual pulse generator.

+: Increment
-: Decrement

Ex. ) To obtain increment or decrement of 10mm/min per one

graduation of pulse generator,

Fmax = 3600mm/min

F=1O= 3~00

thus , K is equal to 360.

-358-
 Consequently, decrement or increment in this example
is 10mm/min per one graduation of pulse generator.

(3) To use this signal, the following conditions should be met.

o1 Automatic operation mode (MEMORY, TAPE or MDI) should be

selected.

o2 The signal should be given during automatic operation.

@ The signal shouldbe given during cutting feed and with

FUNCTION :

This signal specifies a number of the axis component to move in

manual random feed mode.
Components of up to three axes (which depends on the type of
machines) can be moved simultaneously in manual random feed
mode. This signal is used to specify one of them.

OPERATION:

o The manual random feed 1st axis number (CXll - CX116) must be
set before strobe signal CXS8 is turned on. An attempt to set
it during motion shall fail.

o Besides this signal (CX1l - CX116), there are two signals to

specify a manual random feed 2nd axis number (CX21 - CX216)
and a manual random feed 3rd axis number (CX31 - CX316).
The axis numbers need not be specified in ascending order.

o The manual random feed 1st axis number is validated by turning

on the manual random feed 1st axis valid (CXIS) signal
explained later. Similarly, the specific validity signals
(CX2S and CX3S ) are also provided for the 2nd and 3rd axis
number signals.

M330HL Y294 W114

FUNCTION:

In spindle control, S analog data (spindle speed) can be set to

“O” by using this signal (SSTP).

Usually, the signal is not used alone, but combined with “sPin-
dle gear shift” signal (GSET) or “oriented spindle stop” signal
(GORT ).

OPERATION:

When the signal (SSTP) is turned on, S analog data is set to

“o”. Analog data is restored when the signal is turned
off.

When spindle. gear shift signal (SSTP) or oriented spindle stop

signal (GORT) turns on while the signal (SSTP) is on, s analog
data which corresponds to speed set by the spindle speed para.
meter is output.

Note: Spindle speed override is ignored while the signal (SSTP)

is on.

FUNCTION:

Override can be exerted to cutting feedrate during automatic

operation with this signal.

OPERATION:

This signal is valid while “override mode select” signal (FVS)

is off.

When the signal is valid, true feedrate is the product obtained

by multiplying referenced speed by override ratio (%) specified
by the signal (*FV1 - *FV16).
Override ratio is selectable within range from O% to 300% with
an increment of 10%).(Note 1)

Override is 100%, even when the signal is given, in the follow-

ing cases:

(1) When “override cancel” signal is on,

(2) During tapping in canned cycle!

(3) During TAPPING mode (G63), @r

(4) During thread cutting

Only when override ratio setting is O% (all signals “ON”), the

signal (*FV1 - ‘FV16) causes stop to cutting feed and rapid
traverse.

Note 1: If “2nd feedrate override” signal (FV2E) is also valid

(besides FVS) , the 2nd feedrate override ration is also
exerted on the feedrate.

When the signal is turned on, the spindle is indexed in position.

OPERATION:

When this signal is turned on during rotation or stop of the

spindle, deceleration of spindle motor starts and spindle is
indexed.
When the oritented spindle stop is completed, “in-position” sig-
nal (ORAO) is output.

During oriented spindle stop, the control system is under “servo

lock” condition. Servo lock is released when the signal (ORC1)
is turned off during oriented spindle stop.
When servo lock must be maintained, the Signal, therefore, should
be kept turned on.

Direction of spindle rotation in oriented spindle stop depends

on,

(1) direction specified by parameter, or

(2) whether “normal index” (kRN) or “inverse index”

selected.

M330HL R132 R332

FUNCTION:

When “override select mode” (FVS) is set to “file register mode”,

override (O - 300!?!?,
1% increment) can be exerted on the cutting
feedrate. Desired value is set to file register (R) in binary
code.

OPERATION:

When override is exerted to the preset feedrate, the true feed-

rate is the product obtained by multiplying the preset feedrate
by the specified override ratio (provided that “2nd feedrate
override” is not valid).

The override ratio is fixed to 100%, irrespective of 1st feed-

rate override setting, under the following condition:

(1) “Override cancel” signal (OVC) is on,

(2) During tapping in canned cycle,

(3) During TAPPING mode, or

(4) During thread cutting.

Note: Only when override setting is O%, override is exerted

even on rapid traverse speed in automatic operation.
That is, cutting feed as well as rapid traverse stop if
the 1st feedrate override is set to O% during automatic
operation.
When override setting is O%, “MO1 OPEWTION ERROR1! aP-

FUNCTION:

When the 2nd feedrate override function is used, another over.

ride can be exerted on feedrate overrided by “feedrate overridel~
(*FV1 - *FV16) in code feedrate mode, or by “lst feedrate over-
ride (file register mode)”.

The 2nd feedrate override “can be set within range from O% to

327.67% with 0.01% increment.
Value of override ratio is set in binary code system to file re-
gister.

OPERATION:

When this override function is used,” the true feedrate is the

product obtained by multiplying commanded feedrate (F) by “lst
feedrate override” ratio and “2nd feedrate override” ratio.

Since the least increment of 2nd feedrate override is O.01~,

override setting “1OOOO” corresponds to 100%.

The override ratio is fixed to 100’%, irrespective of 1st feed-

rate override setting, under the following condition:

(1) “Override cancel” signal (OVC) is on,

(2) During tapping in canned cycle,

(3) During TAPPING mode, or

(4) During thread cutting.

Note: Only when orride setting is O%, override is exerted even

on rapid traverse speed in automatic operation.
That is, cutting feed as well as rapid traverse stop if
the 1st override feedrate is set to O% during automatic
operation.

FUNCTION:

When file register mode (JVS) is selected for feedrate setting,

feedrate can be specified, besides code mode setting, by setting
desired feedrate ratio manually (value is set to file register
(R)).

OPERATION:
This mode of feedrate setting can be used in JOG FEED, INCREMENT-
AL FEED, REFERENCE POINT RSTRUN FEED and MANUAL RANDOM FEED mode.
For JOG, INCREMENTAL and REFERENCE POINT RETURN mode, “rapid
traverse speed” signal (RFD) should be off.
For MANUAL RANDOM FEED mode, I’EX.F/MODAL.Ft~signal (CXS3) should
be off.

Feedrate specified in this mode can be applied to feed motion in

dry run (automatic operation)

The use of this signal is conditioned .as follows:

(1) When “manual feedrate override valid” signal (OVSL) is off,

the originally set feedrate is applied.

(2) When “m~ual feedrate override valid” signal (OVSL) is on,

the feedrate override ratios of “lst feedrate override” and
“2nd feedrate override” are applied to the origianlly set
feedrate.

(3) Manual feedrate is set to file registers Rn and Rn+l (“n”

differs from model to model).

The feedrate depends on “feedrate least increment” (PCF1,

PCF2) as listed below.

-434-”
 Least.increment

(4) Feedrate clamp (max. feedrate) depends on setting of axis

parameter (cutting feedrate clamp) ...-. when “rapid tra-
verse” signal (RT) is off.

Notes: 1. During INCRGDIENTAL FEED mode, the true feedrate does

not change even when the manual feedrate setting is
changed while feed motion is going on.

2. As for file registers (Rn and Rn+l), Rn is of lower

order.
When feedrate can be set within 16 bits of file re-
gister Rn, register Rn+l may not be used.

FUNCTION:

When “feed multiplication mode select” signal (MPS)

is used, amount of feed per pulse or command” signal can be multi-
plied by value set to file register.
Multiplication value” (multiplier) is set in binary code to file
register (R).

0PER4TION:

Multiplication is applied to amount of feed per pulse in HANDLE

FEED mode (output from manual pulse generator), or to amount of
feed per signal in INCREMENTAL FEED mode (+J1, -Jl, etc.).

When multiplier is “500” and one pulse is given in HANDLE FEED

mode, for example, 500N of feed motion occurs.

When multiplier is I!3000011 feed command signal is given

and one

in INCREMENTAL FEED mode, 30mm of feed motion occurs (time con-

stant for feed motion is equal to time constant for rapid tra.
verse ).

Notes: 1. Change of multiplication setting during feed motion

is ignored.

2. Since considerably large multiplication can be used,

the signal should be used carefully.

OPERATION:
“Manual random feed 1st axis motion data” is for the axis whose
number is specified by “manual random feed 1st axis number (Cxll

“Manual random feed 1st axis motion data” means differently

depending on the statuses of the ‘lMC/WR (CXS5)’f and ‘lABS/INC
(cxs6)” signals.

(1) When the ABS/INC (CXS6) signal is on:

“Manual random feed 1st axis motion data” specifies the amount
of movement (increment).

(2) When the ABS/lNC (CXS6) signal i-s off, it depends on the
status of the MC/WK (CXS5) signal as follows:

When the MC/WK (CXS5) signal is off:

“Manual random feed 1st axis motion data” specifies a

coordinate value (positioning point) of the machine
coordinate system.

When the MC/WK (CXS5) signal is on:

“Manual random feed 1st axis motion data” specifies a
coordinate value (positioning point) of the modal
workpiece coordinate system.

“Manual random feed 1st axis motion data” is written in

binary notation with a sign.
The unit of the specitied
value matches that of data entered.

Ex.: When (R143, R142)=1 is specified in micron system, axis

motion is one micron (at incremental specification).

u. SPINDLECONTROL

11-1 Outline of Functions

Spindle speed can be directly controlled by a S-digit S code command.

When the S analog function specifications are valid, the CNC selects an
appropriate spindle Speed Cor=sportcllng to the S-digit command following the S
code and outputs (spindle gear shift command) it to the machine side (PLC). The
CNC also outputs an appropriate DC voltage (data when the spindle controller is
SR-SF bus-linked) corresponding to the gear input (spindle gear select input) and
commanded speed specified by the machine side (PLC).

11-1-1 Related Parameters

The PLC can have up to four gear stages. The table below lists the four
gear stages and the corresponding parameters.

(1) Spindlelimit speedand maximumspeed

The limit speed and the maximum speed are generally set to the same value so
that the spindle speed becomes the maximum when the spindle motor rotates at
its maximum speed. Because of gear ratio at the machine side, however, it
is sometimes required to make the spindle speed maximum without rotating the
motor at its maximum speed. For this purpose, the spindle limit speed and
maximum speed can be set separately.

IMPORTANT:

The maximum spindle speed parameter is used for determination and clamping
of the spindle gear select output (gear shift command). The spindle limit
speed parameter is used for calculation of an S-analog output voltage
(data).

 1U. SPINDLE CONTROL

Example:
When a motor rotates at its maximum speed, i.e., 4500 rpm (when receiving
10 V, including a controller), the maximum spindle speed is 4000 rpm. (Gear
ratio = 1 : 1)
4000 is set for the par~eter of the maximumspeedand 4500 is set for the
parameterof the limit speed.
When the S 4000 command is issued under this condition, the output voltage
(data) can be determined as follows:

Commanded speed
= A% x lo(v) = 8.89 V
Limit speed

This makes the spindle rotates at 4000 rpm (as specified by the command).

(2) Maximum spindle speed for tap cycle

In tap cycle (including synchronous tap) mode, a maximum spindle speed

(Stapn)specific for a tap cycle operation can be set to minimize inertial.

select the best suited gear stage in tap cycle in place of a
maximum spindle speed (Smaxl to Smax4).

 I u. SPINDLE CONTROL

Note 1: The S-analog output voltage (data) is slwayticomputed from the

spindle speed limit of the gear stage which is determined by the
spindle gear select input (GI1 or G12). Therefore, the spindle
gear select input signal must be controlled carefully. -

Note 2: h S-command for a built-in PLC is stored in file registers R108

and R109. It is valid unless data is loaded in the file registers
from a user PLC.

o1 The maximum DC voltage for spindle control is 10 V. (o to +10 v, plus

or minus 5%)
A spindle speed specified by an S-command can be changed by an
S-command override. If the effective speed (commanded speed x
override) at that time is outside the range between the maximum and
minimum gear speeds (both set by parameters)~ the effective speed is
clamped.

o2 The spindle is stopped (output voltage is O V) when the spindle stop

signal turns on.

o3 When the spindlegear shift input signalturns on while the spindle

stop signalis on, the spindleoutputsan analogvoltageequivalentto
a certain speed for gear shift (gear shift spindle speed: set by a
parameter). The S-command override is invalid then.

o4 When the spindle gear shift input signal turns on while the spindle
stop signal is on~ the spindle outputs an analog voltage equivalent to
a certain speed for orientation (the oriented stop speed is set by a
parameter). The S-command override is invalid then.

o5 Spindle override is invalid (override = 100%),

o when the spindle stop signal is on
o during tapping
o during thread cutting

o6 S-analog voltage (Vso) while the spindle stop signal is on can be

determined according to the following:

(b) For oriented spindle stop command:

(2) The numberof digitsused in a commemlis eightwith a PLC built-inmachine

and two with a standardPLC.

(3) Data can be output either in BCD, binary, or.signed binary codes, which can
be selected by parameters. With a standard PLC, the data output format is
fixed to BCD codes. If S-analog specifications are added on a standard PLC,
however, S-codes are output in binary (8 bits) notation.

(4) Specifying more commands than defined does not cause an error; the last “
command(s) by the number defined will be valid.

Example:
If four commands are specified when a maximum of two T-commands can be
specified:

TO1 T02 T03 T04 ;

The last two commands are valid.

12-2 Miscellaneous Function Complete

The PLC (machine) receives an M-, S-, T-, or B-command output from the CNC
during automatic operation (memory, MDI, or tape) or manual numerical command
operation. When the PLC completes the specified command execution, it returns a
command complete signal to the CNC. There are two types of complete signal as
shown below. lJsethem appropriately in a operation sequence.

(1) FIN1: The CNC proceeds to the next block at the falling edge of the complete
signal (FIN1).

(2) FIN2: The CNC proceedsto the next block at the rising edge of the complete
signal (FIN2).

For more details of the FIN1 and FIN2 signals, see Section 9, Description on
Interface Signals.

These signals are explained below with the M-function.

12-3 M Single Output

The following four types of M-commands output a M-single output signal
(decode signal) in addition to a code signal and MF. The M-single output signal
is generally used for the following contents. The CNC only outputs the decode
signal while the user PLC (machine) ~ecutes the specified operation and
processes the operation complete signal.

Moo : Program stop

Example of processing:
When the MOO command is issued, a block stop status is entered.

MO1 : optional stop

Example of processing:
If the optional stop select switch is on when the MO1 command is
issued, a block stop status is entered.

M02, M30 : Program end

Example of processing:
When the M02 or M30 command is issued, a reset or reset and
rewind signal is returned to the CNC, and then the reset status
1s entered.

12-3-1 Operation Sequence

When MOO, MO1, M02, or M30 is issued during automatic operation (memory,
MDI, or tape) or by a manual numerical command, the M-single output signal is
set. It is reset according to the FIN1, FIN2, reset 1, reset 2, or reset &
rewind signal. .

12-5 Notes on M-, S-, T, and B-functions

(1) H-code data and MF signal output timing (the same is also applicable
.- to the
S-, T-, amd B-code da~a)

With a built-in PLC, M-code data n and MFn signals are output to the user
PLC concurrently. With a standard PLC, the MF s@nal is posted to the
machine side about 40 to 60 msec behind the M-code data signal. If M-code
data and MF signals are output to the PLC-built-in machine side from the
user PLCS insert an appropriate timer into the MF side.

(2) Function complete signals FIN1 and FIN2 are shared by the M-, S-, T-, and
B-functions. Therefore, these signals must be set on condition that all
functions are completed.

(3) While the M-function lock (AFL) signal is set, none of M-, S-, T-, and
B-functions (including an M-command in a fixed cycle) specified in automatic
operation mode (memory, MDI~ or tape) or by a manual numerical command is
executed. That is, none of code data, MF, SF, TF, and BF signals is output
(updated). However, when an M-single output command(MOO,MO1, M02, or M30)
is-issued, M-singleoutput, M-code data, and MF signals are output normally.

(4) A 2nd miscellaneous (B) function can be selected from addresses A, B, and C
according to the machine maker parameters. The function for which address B
is seleeted is called the B-function.
