When you use the forced stop deceleration function
Set [Pr. PA04] to "2 _ _ _" (initial value).
Time constant setting
When you use the forced stop deceleration function, set the same value in the forced stop deceleration time constant [Pr.
PC24] of the drive unit and the rapid stop deceleration time set with the Motion controller.

Difference between the deceleration time constant and the deceleration time
The following shows the difference between the forced stop deceleration time constant and the rapid stop deceleration time.
• Forced stop deceleration time constant (Drive unit)
The time for the servo motor to stop from the rated speed
• Rapid stop deceleration time (Motion controller)
Time for the servo motor to stop from the speed limit value of the Motion controller
Servo motor rated speed
