3. Operation
230
[4] Compulsory Stop (CSTP)
Input
PIO signal
CSTP
This signal is used to forcibly stop the actuator.
Input the CSTP signal continuously for 16ms continuous or longer. Once CSTP Signal is
received, the actuator decelerates and stops with the emergency stop torque, turns the servo
OFF and cut the drive source. At this time, the deviation counter is cleared.
[5] Servo ON (SON, SV)
Input Output
PIO signal
SON SV
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.
At this time, the function selected by the applicable parameter (dynamic brake,
electromagnetic brake or deviation counter clearing) is implemented.

It may differ due to operation condition
and load condition.
z
Servo OFF status
1. Once the actuator stops, no retaining torque will be supplied.
2. The pulse train input, HOME (home return signal), TL (torque-limiting selection signal)
and CSTP (external forced stop signal) are all ignored.
3. Output signals SV (ready signal), HEND (home return complete signal) and TLR (torque
limiting signal) are all cleared (turned OFF).
4. INP (Positioning Completion Signal)
The INP (Positioning Completion Signal) is OFF when the servo is OFF.
