5.3.1 Using the Servo ON Input Signal
The basic use and wiring procedure for the Servo ON (/S-ON) input signal
(sequence input signal) is described below. Use this signal to forcibly turn OFF the
servomotor from the host controller.
This signal is used to turn the servomotor ON and OFF.
The following parameter is used to set the state of the /S-ON signal.

CN1-40
State
Status Result
ON Input Closed
Turns ON the servomotor: operates according
to signal input.
This is the default state.
OFF Input Open
Servomotor cannot operate.
Do not turn OFF the servomotor while it is
operating except in an emergency.
Do not use the Servo ON (/S-ON) signal to start or stop the motor. Doing so will shorten
the life of the servo amplifier. Always use a stop input or command to start or stop the
servomotor.
