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)
Type Name
Input /S-ON
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.
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.
(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.
Parameter
Pn50A
• 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.)
