Set a deceleration time constant for the automatic operation of the indexer method.
Set a deceleration time from the rated speed to 0 r/min.
Additionally, when 20000 ms or more value is set, it will be clamped to 20000 ms.

time constant
This enables to start/stop the servo motor smoothly.
Set the time of the arc part for S-pattern acceleration/deceleration.
Setting "0" will make it linear acceleration/deceleration.
Servo is usually operated with linear acceleration and deceleration; however,
smooth start and stop are enabled by setting [Pr. PC03 S-pattern
acceleration/deceleration time constants]. When the S-pattern
acceleration/deceleration time constants are set, smooth positioning is enabled as
shown in the following figure. Note that when it is set, a time period from the start to
output of MEND (Travel completion) is longer by the S-pattern
acceleration/deceleration time constants.
When the STC value is set longer than the constant speed time, the speed may not
reach to the command speed.
Additionally, when a value of 1000 ms or more is set, it will be clamped to 1000 ms.
