Servo-ON/OFF Operation When the Motor is Rotating
(The following chart shows timing in the case of emergency stop or trip. You cannot use Servo-ON/OFF
repeatedly.)
*1. A value of t1 is a value of Pr6B or time needed for decreasing motor speed to approx. 30 r/min,
whichever is shorter.
*2. Even if SRV-ON signal turns on again during deceleration of the motor, SRV-ON input does not become
active until it stops.
*3. For operation of the dynamic brake during Servo-OFF, also refer to the description of “Sequence at
Servo-OFF” (“Parameter Settings” of every control mode) on Pr69.
*4. Servo-ON input will not be active until the motor rotation speed falls below approx. 30r/min.
Servo-ON/OFF Operation When the Motor is Stopped
(During normal operation, perform the Servo-ON/OFF operation after the motor stops.)
*1. A value of t1 depends on a setting of Pr6A.
*2. For the operation of the dynamic brake during Servo-OFF, also refer to the description of “Sequence
during Servo-OFF” (“Parameter Settings” of every control mode) on Pr69.
*3. Servo-ON input will not be active until the motor rotation speed falls below approx. 30r/min.

When you turn off the power of the electromagnetic brake, the motor brake will run. When you turn on the
power of the electromagnetic brake, the motor brake will be released.
