Servo-On/Off Action While The Motor Is At Stall (Servo-Lock); Servo-On/Off Action While The Motor Is In Motion - Panasonic MINAS A4P Series Instruction Manual

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

Servo-ON input
(SEV-ON)
Dynamic brake
Motor energization
Brake release output
(BRK-OFF)
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.
