2.2.8 Reference Pulse Inhibit Function (INHIBIT)
The reference pulse inhibit function inhibits a Servopack for position control from counting
input reference pulses.
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 between
proportion (P) control and proportional/integral (PI) control for speed loop. (PI control is al-
ways used.)
