-SG to switch the speed amplifier from the proportional integral
type to the proportional type.
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),
switching on the proportion control (PC
) upon positioning completion will
suppress the unnecessary torque generated to compensate for a position shift.
