Reference Pulse Inhibit Function - YASKAWA SGDV User Manual

5.4.8 Reference Pulse Inhibit Function

This function inhibits the SERVOPACK from counting input pulses during position control. When this func-
tion is enabled, the SERVOPACK does not accept the reference pulse input.
(1) Factory-set Input Signal Allocations (Pn50A.0 = 0)
Use Pn000.1=B and the /P-CON signal to use the reference pulse inhibit function while the input signal allo-
cations are still in the factory settings.

Note: If Pn000.1 is set to B, the /P-CON signal cannot be used for any function other than the reference pulse inhibit func-
tion.
(2) Changing Input Signal Allocations (Pn50A.0 = 1)
Allocate the /INHIBIT signal as the reference pulse inhibit signal to use the reference pulse inhibit function
while the Pn000.1 (control method) is set to 1 or 5.
