8.6.7 Reference Pulse Inhibit Function (INHIBIT)
(1) Description
This function inhibits the SERVOPACK from counting input pulses during position control. The servomotor
remains locked (clamped) while pulse are inhibited.

ON (low level) Turns the INHIBIT function ON.
(Inhibits the SERVOPACK from counting refer-
ence pulses.)
OFF (high level) Turns the INHIBIT function OFF.
(Counts reference pulses.)
These input signals enable the inhibit function.
Either the /P-CON or the /INHIBIT signal can be used to switch the inhibit signal. The input signal must be allocated in
order to use the /INHIBIT signal. Refer to
7.3.2 Input Circuit Signal Allocation .
