Alarm PS0552, "SP-MODE CHANGE COMMAND
ERROR" is issued because parameter No.25802 of
third spindle is 0.

If M code for Cs contour control ON is commanded, spindle speed command is set to 0 in order not to
rotate the spindle when Cs contour control is canceled. Therefore, S code has to be newly commanded for
rotating the spindle after Cs contour control OFF. In Multi-spindle control, if spindle selection method by
spindle selection signals SWS1 to SWS4 <Gn027.0, Gn027.1, Gn027.2>, <Gn026.3> is used, select
spindle by spindle selection signals before commanding S code. If S code has not been commanded in the
path from which M code for Cs contour control ON is commanded and only M03/M04 is commanded,
alarm PS0554, "S-CODE IS NOT COMMANDED" is issued in order not to start machining without
spindle rotation. If only M code except for M03/M04 is commanded, alarm PS0554 is not issued. If M
code except for M03/M04 is used for spindle rotation, be sure to command S code in order not to start
machining without spindle rotation.

NOTE

1 G code using address P, address Q, or address R and M code for Cs contour

control ON or M code for Cs contour control OFF cannot be commanded in the
same block. When spindle selection by address P is available, if machine
coordinate system select command (G53) is commanded, alarm PS0552,
"SP-MODE CHANGE COMMAND ERROR" is issued.
When spindle selection by address P is available and the addition of workpiece
coordinate system 48 pairs or 300 pairs is available, if selecting a workpiece
coordinate system (G54) is commanded, alarm PS0552, "SP-MODE CHANGE
COMMAND ERROR" is issued.

2 Cs contour control by program command is not canceled by emergency stop,

reset. However, if emergency stop or reset is executed during M code for Cs
contour control ON, Cs contour control is canceled.

3 In changing Cs contour control, if CW command signals SFR or CCW command

signals SRV has to be changed by PMC ladder, Cs contour control change
completion signal FSCSL<Fn044.1> or Cs contour control change completion
signal in each axis FCSS1 to FCSS4<Fn274.0 to Fn274.4> is available (bit 3
(NCS) of parameter No.3729 has to be set to 1 (switching to Cs contour control
is completed even when the spindle activating current is off)).

4 S code has to be newly commanded for rotating the spindle after canceling Cs

contour control by program command. If S code has not been commanded in the
path from which M code for Cs contour control ON is commanded and only
M03/M04 is commanded, alarm PS0554, "S-CODE IS NOT COMMANDED" is
issued. If only M code except for M03/M04 is commanded, alarm PS0554 is not
issued. Be sure to command S code if M code except for M03/M04 is used for
spindle rotation in order not to start machining without spindle rotation.

5 Multiple M commands in a single block cannot be used. Don’t command other M

codes with M code for Cs contour control ON or M code for Cs contour control
OFF in the same block.

6 Enabling spindle serial output (bit 5 (SSN) of parameter No.8133 is 0) and Cs

contour control (bit 2 (SCS) of parameter No.8133 is 1) is required in order to
use this function.

- Spindle control mode OFF

Spindle orientation by program command or Cs contour control by program command can be canceled by
M codes which are set to parameter No.25804, No.25805, and No.25806. The spindle whose parameters
(No.25804, No.25805, and No.25806) are set to 0 cannot use M codes for spindle control mode OFF.
If spindle selection by address P of Multi-spindle control is enabled (bit 3 (MPP) of parameter No.3703 is
1), spindle canceling spindle control mode can be selected by address P. Spindles canceling spindle
control mode by program command use the same M code for spindle control mode OFF. Set the same M
code to parameter of spindle canceling spindle control mode (refer to Example (10)).
When M code for spindle control mode OFF (parameter No.25804, No.25805, and No.25806) is
commanded, auxiliary function code signals M00 to M31<Fn010 to Fn013> and auxiliary function strobe
signal MF<Fn007.0> are output.

When spindle selection by address P is available and the addition of workpiece
coordinate system 48 pairs or 300 pairs is available, if selecting a workpiece
coordinate system (G54) is commanded, alarm PS0552, "SP-MODE CHANGE

2 S code has to be newly commanded for rotating the spindle after canceling

spindle control mode by M code. If S code has not been commanded and only
M03/M04 is commanded, alarm PS0554, "S-CODE IS NOT COMMANDED" is
issued. If only M code except for M03/M04 is commanded, alarm PS0554 is not
issued. Be sure to command S code if M code except for M03/M04 is used for
spindle rotation in order not to start machining without spindle rotation.

3 If M03/M04 is set as M code for spindle control mode OFF, S code has to be

command with M03/M04 in the same block. If S code is not commanded, alarm
PS0554 is issued.

4 If Multiple M commands in a single block is used, command M code for spindle

control mode OFF as the first M code.

- Spindle control mode OFF by signal

Spindle orientation by program command or Cs contour control by program command can be canceled by
spindle control mode off signals MDOFF1 to MDOFF4<Gn586.4 to Gn586.7>. If you want to cancel
spindle orientation or Cs contour control by emergency stop, reset, and so on, spindle control mode can
be canceled by spindle control mode off signals MDOFF1 to MDOFF4<Gn586.4 to Gn586.7>. If spindle
control mode off signal MDOFF1 to MDOFF4<Gn586.4 to Gn586.7> is set to "1", spindle control mode
is canceled. If spindle orientation is canceled, spindle orientation completion signal ORARA to
ORARD<Fn045.7, Fn049.7, Fn168.7, Fn266.7> is set to "0". Then, set "0" to spindle control mode off
signals MDOFF1 to MDOFF4<Gn586.4 to Gn586.7>. If Cs contour control is canceled, Cs contour
control change completion signal FSCSL<Fn044.1> or Cs contour control change completion signal in
each axis FCSS1 to FCSS4<Fn274.0 to Fn274.3> is set to "0". Then, set "0" to spindle control mode off
signals MDOFF1 to MDOFF4<Gn586.4 to Gn586.7>.

Similarly, Cs contour control by Cs contour control change signal CON<Gn027.7> or Cs contour control
change signals in each axis CONS1 to CONS4<Gn274.0 to Gn274.3> cannot be canceled by spindle
mode off signals MDOFF1 to MDOFF4<Gn586.4 to Gn586.7>.
When spindle control mode off signal MDOFF1 to MDOFF4<Gn586.4 to Gn586.7> is "1", if M code for
spindle orientation ON set to parameter No.25800 or M code for Cs contour control ON set to parameter
No.25802 is commanded, alarm PS0553, "SP-MODE CHANGE IMPOSSIBLE" is issued.

- Multi-spindle address P signals

If bit 0 (ADP) of parameter No.25807 is set to 1, the value of address P which is commanded to select
mode changing spindle is output to multi-spindle address P signals MSP00 to MSP15<Fn160.0 to
Fn161.7>.

Limitation

- Command with a signal

M code for spindle control mode changing is not output to MDI program by auxiliary function output in
program restart function.

- Auxiliary function output in moving axis

If M code for spindle control mode changing is commanded in G50.9 block, alarm PS5330 "G50.9
FORMAT ERROR" is issued.

- Hypothetical Cs axis

Spindle control mode changing by program command is not available for hypothetical Cs axis. Set 0 to
parameters Nos.25800 to 25806.

- Spindle control with servo motor

Spindle control mode changing by program command is not available for spindle controlled with servo
motor. Set 0 to parameter Nos.25800 to 25806.

- Canned cycle for drilling

In Fine boring cycle (G76) and Back boring cycle (G87), M19 is output in order to execute spindle
orientation during canned cycle. If M19 is set as M code for spindle orientation by program command,
M19 in Fine boring cycle (G76) and Back boring cycle (G87) does not execute spindle orientation by
program command, auxiliary function code signals M00 to M31<Fn010 to Fn013> and auxiliary function
strobe signal MF<Fn007.0> are output. Spindle orientation M19 in Fine boring cycle (G76) and Back
boring cycle (G87) has to execute by PMC ladder.

[Classification] Input signal

[Function] In spindle control mode changing by program command, spindle orientation by program

command or Cs contour control by program command is canceled.

[Operation] If spindle control mode off signal MDOFF1 to MDOFF4<Gn586.4 to Gn586.7> is set to

"1", spindle orientation by program command or Cs contour control by program
command is canceled. If spindle orientation completion signal ORARA to
