The reset signal RES has two functions: it resets the alarm when an alarm is generated and
suspends operation when it is in pause.
(1) If this signal is turned ON while an alarm of operation cancel level is being generated, the
alarm will be canceled. (For a cold start level alarm, the power must be turned on again.)
Check the cause of the alarm and resolve the cause before resetting the alarm. Resetting
the alarm repeatedly without resolving the cause and repeating the activation may cause
serious malfunction such as motor burnout.
(2) If this signal is turned from OFF to ON while paused, it is possible to cancel the remaining
travel distance and interrupt the operation.
[5] Servo ON command (SON) PLC output signal
Servo ON status (SV) PLC input signal
Positioning complete (PEND) PLC input signal

(1) The servo ON command signal SON is a signal that puts the actuator into an operable
status.
(2) When servo is turned ON and operation is enabled, the servo ON signal SV turns ON. At the
same time, the positioning complete signal PEND turns ON.
Also, the SYS of the driver unit LED of the corresponding axis No. on the front panel lights
up in green.
(3) Even if power is supplied to the controller, it cannot be operated while the SV signal is OFF.
When the SON signal is turned OFF while the actuator is in operation, the actuator stops
and the servo turns OFF.
For actuator with brake, the brake will activate.
Note 1: PEND is not turned on while in pause.
