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 maximam 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.
T (before detecting excitation)
(Note 1)
= SON signal identification (6ms) + Excitation detection time (T1 + T2)
× Number of retry (10 times Max.) + Servo ON delay time (T3)
T (after detecting excitation)
(Note 1)
= SON signal identification (6ms) + Servo ON delay time (T3)
T1 : Parameter No.30 It differs depending on the setting of excitation detection type.
Set Value = 0 → 160ms
Set Value = 1, 2 → 220ms
T2 : Parameter No.29 Setting of excitation phase signal detection time
It is set to 10ms in the initial setting.
T3 : Fixed to 20ms
Note 1 Excitation check operation is performed at the first servo-on process after the power is
turned on for the incremental type and absolute battery type, and when the home return
is completed for the simple absolute type to identify the magnetic poles of the motor.
Note 2 PEND would not turn ON in the pause condition.
