Panasonic A4P Series Servo-ON/OFF Action While the Motor Is at Stall Servo-Lock, Servo-ON input

[Operation Setting]

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

Servo-ON input￿		OFF		ON		OFF
(SEV-ON)
			approx.2ms		1 to 5ms
Dynamic brake	engaged *3			released			engaged *2
						t1 *1
Motor energization	not-energized			energized			not-energized
		approx.40ms
Brake release output￿				approx.2ms
		engaged (OFF)		released (ON)		engaged (OFF)
(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.

(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.
