DI Wiring
The users can define the DI function by editing user parameters, see the following table for
details:

Servo ON SON
If SON is ON, the basic circuit is on and servo is ready to
run(servo ON status).
If SON is OFF, the basic circuit is off and the servo motor is
in free run status(servo OFF status).
ALL
Reset RES
If the RES is ON for over 50ms, reset is valid, but may not
able to clear an abnormal alarm status (refer to section 11.
1). The circuit is still on when set PD20 to XXX1.
ALL
Proportion
control
PC
The speed controller will switch from proportion integral
control to proportion control when PC signal is ON. When
servo motor stops, any external pulse will generate torque
to adjust the position shift. Once the positioning is
done(stopped) and machine shaft is locked, the PC signal
will be on and the unnecessary torque adjustment will be
suppressed. If you want to lock the servo for long time, you
need to turn on both the PC signal and the TL signal at the
same time, the analog torque limit will control it below the
rated torque.
