4.5.2 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.
This signal is used to turn the servomotor ON and OFF.
Do not use the Servo ON (/S-ON) signal but rather always use an input reference signal to start or stop
the servomotor.
Set the following parameter to 7 if the /S-ON signal will not be used.

Position Control
CN1-40 is
ON (Low
Level) Turns the servomotor ON. This is the
normal state (called the Servo ON state). Servo ON Servomotor is ON.
The servomotor operates
according to signal input.
CN1-40 is
OFF (High
Level) Turns the servomotor OFF. The servo-
motor is OFF and cannot operate (called
the Servo OFF state). Do not turn the
servomotor OFF while it is operating
except in an emergency. Servo OFF Servomotor is OFF.
Servomotor cannot oper-
ate.
