5.5.2 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.
ð Input /S-ON CN1-40

• Do not use the Servo ON (/S-ON) signal to start or stop the motor. Always use an input reference sig-
nal, 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.
