5.2.1

Servo ON Signal

This sets the servo ON signal (/S-ON) that determines whether the servomotor power is ON or OFF.

Type
Input
Note: Use parameter Pn50A.1 to allocate the /S-ON signal to another terminal. For details, refer to 3.3.1 Input Signal Allo-
cations for details.
(2) Settings for Continuous Servo ON Signal
Parameter Pn50A.1 can be used to enable the Servo ON condition constantly.

[Factory setting]
Always input the servo ON signal before inputting the speed/position/torque reference to
start or stop the servomotor. Do not input the references first and then use the servo ON
signal or turn ON/OFF the power supply to start or stop. Doing so will degrade internal
elements and lead to accident. Input the servo ON signal while the servomotor stops.
While the servomotor is rotating, the servo ON signal cannot be input.
Parameter
n. 0
Inputs the servo ON signal from the input terminal
[Factory setting] CN1-15.
n. 7 Constantly enables the servo ON signal.
SERVOPACK operation will be possible (i.e., power will be supplied) when the main cir-
cuit power supply is turned ON if the servo ON signal is set to be always enabled. When
inputting speed/position/torque reference, be sure to implement safety measures for
unexpected operation of the servomotor and machine.
SERVOPACK operation will be possible (i.e., power will be supplied) when an alarm is
reset after an alarm occurs. The servomotor or machine may operate unexpectedly if an
alarm is reset while a reference is being input.
Setting
Servomotor power is ON. Servomotor
ON
can be operated.
Servomotor power is OFF. Servomo-
