S-pattern
acceleration/
deceleration
time constant This parameter is used to smooth start/stop of the servo motor.
Set the time of the arc part for S-pattern acceleration/deceleration.
Setting "0" will make it linear acceleration/deceleration.
The parameter is effective only after rebooting the power once the
parameter values setup is completed.

STA: Speed acceleration time constant (Point table setting value)
STB: Speed deceleration time constant (Point table setting value)
STC: S-pattern acceleration/deceleration time constant ([Pr. PC03])
If the STA or STB is set long, the setting of the S-pattern acceleration/
deceleration time constant may result in the deviation with the time at the
inflection point area.
When a value of 1000 ms or larger is set, the parameter value is clamped
to 1000 ms. The setting is disabled during home position return.

When the [Pr. PN08] is "_ _ _ 1", the setting value of this parameter is
effective. When the [Pr. PN08] is "_ _ _ 0", regardless of the setting value
of this parameter, the occurrence condition of [AL. E9] is "detected only
by servo on command".
