Using the Servo ON Input Signal (/S-ON)

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.
Input /S-ON CN1-40
This signal is used to turn the servomotor ON and OFF.

• Do not use the Servo ON (/S-ON) signal to start or stop the motor. Always use an input reference
signal, such as Speed Reference to start or stop the servomotor.
Doing so will shorten the life of the servo amplifier.
Set the following parameter to 7 if the /S-ON signal will not be used.
