PI-PID switching control selection
0: PI control enabled
(Switching to PID control is possible with commands
of servo system controller.)
3: Continuous PID control enabled
If the servo motor at a stop is rotated even one pulse
due to any external factor, it generates torque to
compensate for a position shift. When the servo motor
shaft is to be locked mechanically after positioning
completion (stop), enabling PID control and
completing positioning simultaneously will suppress
the unnecessary torque generated to compensate for
a position shift.
