5.2.11 Reference Pulse Inhibit Function (/INHIBIT)
This function inhibits the servo amplifier from counting input reference pulses
during position control. The servomotor remains locked (clamped) while the
function is in use. The /P-CON(/INHIBIT) signal is used to enable or disable the
function.
Using Reference Pulse Inhibit Function (/INHIBIT)
To use the inhibit function, set the parameter as shown below.
The following settings enable the inhibit function.
Note: Parentheses ( ) around an /INHIBIT signal indicate that a signal has been allocated to the input circuit.
See 5.3.3 Input Circuit Signal Allocation for more details.
