Reference Pulse Inhibition Function

You can stop the SERVOPACK from counting the reference input pulses during position con-
trol. When this function is enabled, the SERVOPACK will ignore the reference pulse input.
/INHIBIT (Reference Pulse Inhibit) Signal
If you set the control method to switch between normal position control and position control
with reference pulse inhibition (Pn000 = n.B), the /INHIBIT signal is used as the Refer-
ence Pulse Inhibit signal (default setting).
 When Using the Default Input Signal Allocations (Pn50A = n.0)
Type
Input
 When Changing Input Signal Allocations (Pn50A = n.1)
If you set Pn000 = n.X (Control Method Selection) to 1, 5, 7, or 8, the /INHIBIT signal is
used as the Reference Pulse Inhibit signal for reference pulse inhibition.
Type
Input
Note: You must allocate the /INHIBIT signal to use it. Use Pn50D = n.X (/INHIBIT (Reference Pulse Inhibit
Input) Signal Allocation) to allocate the signal to a connector pin. Refer to the following section for details.
 Reference Pulse Inhibition Settings
To use reference pulse inhibition, set Pn000 = n.X (Control Method Selection) to 1, 5, 7 or
8.
