CHAPTER 3 OPERATION
3.3.7
Interrupting/Stopping Operation
The following input signals interrupt or stop each operation.
・STO (EN terminal input)
・Servo-on [S-ON]
・+OT/-OT
・Forced stop [EMG]
3
・Positioning cancel
・Deviation clear
・Free-run
(1) STO (EN terminal input)
If terminals [EN1+] or [EN2+] are opened while the motor is running, the STO function will be
triggered, and the motor will free run to a stop.
The operation when decelerating is based on the operation setting when PA2_61 servo-on is OFF.
When servo-on is OFF, however, the operation when decelerating will be "dynamic brake
operation" when the "Deceleration speed" is set.
(2) Servo-on [S-ON]
If servo-on [S-ON] is turned OFF while the motor is running, operation is stopped, and the motor is
stopped based on the PA2_61: Action sequence at servo-on OFF setting. If rapid deceleration is
selected, the motor will decelerate based on the PA2_60: Third torque limit torque.

(1) If free-run when decelerating is selected with PA2_61: Action sequence at
servo-on OFF, the motor will continue to run for a short while under its own
inertia.
(2) The in-position [INP] signal shown in the figure indicates the state in the level
output mode.
