No. SR-DSV09485 - 46 -A4P MOTOR COMPANY, MATSUSHITA ELECTRIC INDUSTRIAL CO.,LTD7-3 Servo-ON/OFF Operation Timing during Motor Stop (Servo Lock)(During normal operation, perform the Servo-ON/OFF operation after the motor stops.)*1. "t1" depends on the setting of Servo parameter No. 6A (Mechabreak operation setting at stop).*2. For the operation of the dynamic brake in the Servo-OFF status, refer to the description on Servoparameter No. 69 (Sequence at servo-off).*3. The Servo-ON input does not become active until the motor speed falls below approx. 30 r/min.*4. Once servo is turned off, present position output ( X5 P1OUT - P32OUT: Pin 29, 30, 31, 32, 33, and34) is retained the same as previous operation until the next point operation is completed.7-4 Servo-ON/OFF Operation Timing during Motor Run(The following chart shows the timing in emergency stop or trip. The Servo-ON/OFF cannot berepeatedly used.)*1. "t1" is the time defined by Servo parameter No. 6B (Mechabrake operation setting at operation) or thetime required to decrease the motor speed to approx. 30 r/min, or less whichever is earlier.*2. For the operation of the dynamic brake in the Servo-OFF status, refer to the description on Servoparameter No. 69 (sequence at Servo-OFF).*3 The Servo-ON input does not become active until the motor speed falls below approx. 30 r/min.*4 Once servo is turned off, present position output ( X5 P1OUT - P32OUT: Pin 29, 30, 31, 32, 33, and34) is retained the same as previous operation until the next point operation is completed.Servo-ON input(SRV-ON)OFFDynamic brakeMotor energizedBRK-OFF(X5, BRK-OFF Pin 36)ON OFFEngaged *3 Engaged *2ReleasedApprox. 2 ms1 to 5 msNot energizedApprox. 40 msNot energizedEnergizedBrake engaged(OFF) Brake released (ON) Brake engaged(OFF)Approx. 2 mst1 *1t1 *1t1 *1Servo-ON input(SRV-ON) OFFDynamic brakeMotor energizedBRK-OFF(X5, BRK-OFF Pin 36)ON OFFEngaged *3 Engaged *3ReleasedApprox.1 to 5 msNot energized Not energized *5EnergizedBrake released (ON) Brake engaged(OFF)Approx. 2 msBrake engaged(OFF)Approx. 40 msPr. 6B set valuePr. 6B setvalueMotor speedMotor rpmApprox. 30 r/minServo enabledThe Servo-ON input does notbecome active until the motor speedfalls below approx. 30 r/min.Motor speedMotor speedApprox. 30 r/minApprox. 30 r/minBrake released(ON) Brake engaged(OFF)The timedefined by Pr.6B is reachedearlier.The motorspeed fallsbelow 30 r/minearlier.*4
