3.2.10 Using the Reference Pulse Inhibit Function (INHIBIT)
This function causes the SERVOPACK to stop counting input reference pulses in posi-
tion control mode.
While this function is being used, the motor remains in servo locked (clamped) status.
The /P-CON signal is used to enable or prohibit this function.
When this function is used, therefore, the /P-CON signal cannot be used to switch be-
tween proportion (P) control and proportional/integral (PI) control for speed loop. (PI con-
trol is always used.)
