8.3.1 Setting the Servo ON Signal
This sets the servo ON signal (/S-ON) that determines whether the servomotor power is ON or OFF.
(1) Servo ON signal (/S-ON)
(2) Enabling/Disabling the Servo ON Signal
A parameter can be always used to set a parameter servo ON condition. This eliminates the need to wire /S-ON,
but care must be taken because the SERVOPACK can operate as soon as the power is turned ON.
Type Name Connector Pin
Number
Setting Meaning
Input /S-ON CN1-40
(Factory setting) ON (low level) Servomotor power ON. Servomotor can be operated.
OFF (high
level) Servomotor power OFF. Servomotor cannot be operated.
„ IMPORTANT
Always input the servo ON signal before inputting the input reference to start or stop the servomotor. Do not input the input
reference first and then use the /S-ON signal to start or stop. Doing so will degrade internal elements and lead to malfunc-
tion.
Note: A parameter can be used to re-allocate the input connector number for the /S-ON signal. Refer to
7.3.2 Input Circuit Signal Allocation.
Parameter Meaning

0
† Inputs the /S-ON signal from the input terminal CN1-40. (Factory setting)
n. †† 7 †
Constantly enables the /S-ON signal.
• After changing these parameters, turn OFF the main circuit and control power supplies and then turn them ON again to
enable the new settings.
• When the parameter is set to constantly “enable” the signal, resetting an alarm can only be done by turning the power
OFF and ON. (Alarm reset is disabled.)
