Setting Method - Mitsubishi Electric MELSERVO-J5 User Manual

Setting method

Setting with servo parameters
[Pr. PT68.0 Quick stop method selection] can be used to specify the deceleration stop operation method. [Pr. PT68.0]
corresponds to [Quick stop option code (Obj. 605Ah)].
Servo Name

PC24 Deceleration time constant at forced stop

PT68.0 Quick stop method selection
*1 The servo parameter to be set varies depending on the unit selected in [Pr. PT01.1 Speed/acceleration/deceleration unit selection].
However, the same object is used for setting the acceleration/deceleration data regardless of the unit selected. For details, refer to "[Pr.
PT01.1 Speed/acceleration/deceleration unit selection]" in the User's Manual (Parameters).
*2 Available on servo amplifiers with firmware version D0 or later.
*3 Not available for CC-Link IE Field Network Basic.
*4 For the deceleration time constants of the control modes, refer to "[Quick stop option code (Obj. 605Ah)]" in the User's Manual (Object
Dictionary).
*5 When the controller being used cannot perform follow-up in the "Quick stop active" state (during servo-on), do not use this setting value
in the cyclic synchronous position mode (csp). For information on whether the controller being used can perform follow-up in the "Quick
stop active" state, refer to the manual for the controller.
*6 When canceling Quick stop in the cyclic synchronous position mode (csp), cancel it after servo-off or perform position follow-up with the
controller. If Quick stop is canceled without performing position follow-up, the servo motor may suddenly accelerate.

3.21 Quick stop [G]
Outline
Set the deceleration time constant at forced stop.
Initial value: 100 [ms]
Set the deceleration to be used for the forced stop deceleration function.
2
Initial value: 0 [command unit/s ]
Select the quick stop method.
In the slave axis torque mode (slt), the servo motor ignores the Quick Stop
input and decelerates to a stop in accordance with the stop command from the
master axis regardless of the setting value of this servo parameter. For details,
refer to "Master-slave operation simultaneous stop function" in the User's
Manual (Communication Function).
Forced stop deceleration by turning off EM2 (Forced stop 2) is the same as "2"
(servo-off after deceleration to a stop with [Quick stop deceleration (Obj.
6085h)]) regardless of the setting value of this servo parameter.
When [Pr. PA04.3 Forced stop deceleration function selection] is set to "0"
(forced stop deceleration function disabled), the servo motor stops with the
dynamic brake regardless of the setting value of this servo parameter.
*2
0: Stop with dynamic brake
1: Servo-off after deceleration to a stop at the deceleration time constant of any
*2*4
of the control modes
2: Servo-off after deceleration to a stop with [Quick stop option code (Obj.
605Ah)]
5: Maintain servo-on after deceleration to a stop at the deceleration time
constant of any of the control modes
6: Maintain servo-on after deceleration to a stop with [Quick stop option code
