Forced stop deceleration time constant
Set a deceleration time constant when you use the forced stop deceleration function.
Set the time per ms from the rated speed to 0 r/min or 0 mm/s. Setting "0" will be 100
ms.

[Precautions]
If the servo motor torque is saturated at the maximum torque during forced stop
deceleration because the set time is too short, the time to stop will be longer than
the set time constant.
[AL. 50 Overload alarm 1] or [AL. 51 Overload alarm 2] may occur during forced
stop deceleration, depending on the set value.
After an alarm that leads to a forced stop deceleration, if an alarm that does not
lead to a forced stop deceleration occurs or if the control circuit power supply is
cut, dynamic braking will start regardless of the deceleration time constant
setting.
Set a longer time than deceleration time of the controller. If a shorter time is set,
[AL. 52 Error excessive] may occur.
