Caution
*1. t1 will be a shorter time of either the setup value of Pr4.38 “Mechanical brake action
at running setup” or elapsing time for the motor speed to fall below
Pr4.39 “Brake re-
lease speed setup”
.
*2. Even though the SRV-ON signal is turned on again during the motor deceleration,
Servo-ON will not be activated until the motor stops.
*3. For the action of dynamic brake at alarm occurrence, refer to an explanation of
Pr5.06, “Sequence at Servo-OFF” as well.
*4. Servo-ON will not be activated until the motor speed falls below approx. 30r/min.
*5.
For the motor energization during deceleration at Servo-OFF depends on the setup value
of Pr.5.08, “Sequence at Servo-OFF”.
