12 DATA USED FOR POSITIONING CONTROL
12.3 Basic Setting

12
[Pr.17] Torque limit setting value
Set the maximum value of the torque generated by the servomotor as a percentage between 0.1 and 1000.0%.
*1
The torque limit function limits the torque generated by the servomotor within the set range.
If the torque required for control exceeds the torque limit value, it is controlled with the set torque limit value.

[Pr.18] M code ON signal output timing
This parameter sets the M code ON signal output timing.
Choose either WITH mode or AFTER mode as the M code ON signal output timing.
■
RD77MS4 operation example
*1
m1 and m2 indicate set M codes.
*2
If AFTER mode is used with speed control, an M code will not be output and the M code ON signal will not be turned ON.
An M code is a number between 0 and 65535 that can be assigned to each positioning data ([Da.10]).
The program can be coded to read an M code from the buffer memory address specified by "[Md.25] Valid M code" whenever
the M code ON signal turns ON so that a command for the sub work (e.g. clamping, drilling, or tool change) associated with
the M code can be issued.
*1
The M code ON signal output timing can be set to each positioning data using the positioning option of the positioning data ([Da.27]).
[Pr.19] Speed switching mode
Set whether to switch the speed switching mode with the standard switching or front-loading switching mode.
Setting value
Details
0: Standard switching
Switch the speed when executing the next positioning data.
1: Front-loading switching
The speed switches at the end of the positioning data currently being executed.
WITH mode: An M code is output and the M code ON
signal is turned ON when a positioning
operation starts.
