Servo-ON/OFF Action While the Motor Is at Stall (Servo-Lock)

Caution

*1. t1 will be determined by SV.Pr6A setup value.
*2. For the dynamic brake action at Servo-OFF, refer to an explanation of SV.Pr69, "Sequence at Servo-

OFF ("Parameter setup" at each control mode) as well.

*3. Servo-ON will not be activated until the motor speed falls below approx. 30r/min.
*4. Once the servo turns off, the current position output (P1OUT to P32OUT: CN X5 Pin 29, 30, 31, 32, 33

and 34) is held to be unchanged until the next point operation is completed.

Servo-ON/OFF Action While the Motor Is in Motion

(Timing at emergency stop or trip. Do not repeat this sequence. During the normal operation, stop the motor,
then make Servo-ON/OFF action.)

Caution

*1. t1 will be a shorter time of either the setup value of SV.Pr6B or elapsing time for the motor speed to fall

below 30r/min.

*2. For a dynamic brake operation during servo off and a motor operation state during deceleration, refer to

the explanation of SV.Pr69 (sequence at servo off) also.

*3. For the action of dynamic brake at alarm occurrence, refer to an explanation of Pt69, "Sequence at

Servo-OFF ("Parameter setup" at each control mode) as well.

*4. Once the servo turns off, the current position output (P1OUT to P32OUT: CN X5 Pin 29, 30, 31, 32, 33

and 34) is held to be unchanged until the next point operation is completed.
