Operation
5.4.7 Reference Pulse Inhibit Function
This function inhibits the SERVOPACK from counting input pulses during position control. The servomotor
remains locked (clamped) while pulse are inhibited.
<Terms>
Servo lock: A stopped state of the motor in which a position loop is formed with a position reference of 0.
(1) Factory-set Sequence Signal Allocations (Pn50A.0 = 0)
Use the /P-CON signal to switch to the reference pulse inhibit function.
To use the reference pulse inhibit function, set Pn000.1 to B.
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 Sequence Signal Allocations for Each Signal (Pn50A.0 = 1)
Use the /INHIBIT signal to switch to the reference pulse inhibit function.
To use the /INHIBIT signal, the input signal must be allocated. For details, refer to 3.3.1 Input Signal Alloca-
tionss to Input Terminals.
