1) Servo ON signal SON is the input signal making the servo motor of the actuator operable.

2) If the servo-on is performed to enable operation, the SV output signal is turned ON.

Concurrently positioning completion signal PEND is turned ON.

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 forced stop torque. After the stop, the servo OFF

occurs to enter the motor into the free running state.

The brake (option) is of release-in-excitation type. Therefore, making the excitation on will

release the brake while making it off will lock the brake.
