3.2.10Using the Reference Pulse Inhibit Function (INHIBIT)
For position control (SGDA-
jjj
P) only.
1) Outline
This 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 be-
tween proportion (P) control and proportional/integral (PI) control for speed loop. (PI con-
trol is always used.)

Note: Whether INHIBIT function is used, select by bit F of Cn−01.
2) How to Use Reference Pulse Inhibit Function (INHIBIT)
To use the INHIBIT function, set the bit F of memory switch Cn−01 to 1:

Setting Meaning
0
Does not use the INHIBIT function.
Reference pulses are always counted.
Uses the INHIBIT function.
P-CON
signal is used to enable or prohibit the INHIBIT function.
P-CON Meaning
OFF Counts reference pulses.

ON
Prohibits the Servopack from counting reference
pulses.
The motor remains in servo locked (clamped)
status.
