3.8 Control and functions of Input and output signals of Remote I/O Mode
3.8.1 Operation Supportive Signal = Patterns 0 to 2, 4 and 5 in common
[1] Emergency stop status (EMGS)

1) The emergency stop status EMGS is turned ON when in normal condition and turned
OFF when it opens between EMG+ and EMG- (emergency stop condition or
disconnected) for “Emergency Stop Circuit”.
2) The signal turns on once the emergency stop condition is cancelled and it closes
between EMG+ and EMG-.
Have an appropriate safety treatment such as interlock with this signal for the host controller
(PLC, etc.).
(Note) It is not an emergency stop output due to an alarm generation of the controller.

1) Servo ON command SON is the signal making the servo motor of the actuator operable.
2) If the servo-on is performed to enable operation, the servo ON status signal SV output
signal is turned ON.
Also, the status LEDs for driver (SV) on the front panel corresponding for the axis number
turns on in green. [Refer to Name for Each Parts and Their Functions 7) Status LEDs for
Driver]
3) With the power being supplied, then controller cannot be operated while the SV signal
remains OFF. If the SON signal is turned OFF under operation of the actuator, the
actuator is decelerated and stopped with the emergency stop torque, the servo is turned
OFF and the motor gets into the free-run condition.
For the actuators equipped with a brake, the brake gets activated.

Note1 PEND would not turn ON in the pause condition.
