after the motor stops.
(DB: Dynamic Brake operation)
Also see Timing Chart “After an Alarm event” on Page 33 of Preparation edition.
The parameter sets the following:
1) Driving conditions during deceleration or after stop
2) Clear operation of the deviation counter
after Servo-OFF (SRV-ON signal: CN X5 pin 2 turns on off) is turned on.
(DB: Dynamic Brake operation)
Also see Timing Chart “Servo-ON/OFF Operation When the Motor is Stopped” on
Page 34 of Preparation edition.
The parameter enables you to set time from when the brake release signal (BRK-

when you turn on Servo-OFF while the motor is stopped.
