5 DATA USED FOR POSITIONING CONTROL
Pr.1
WITH mode......... An M code is output and the M code ON
signal is turned ON when a positioning
operation starts.

Da.1
: m1 and m2 indicate set M codes.
Note: 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.
Pr.17 Torque limit setting value
Set the maximum value of the torque generated by the servomotor as a
percentage between 1 and 500%.
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.
(Refer to "12.4.2 Torque limit function ".)

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.
