Feed-forward timing adjustment coefficient
Unit of data : 0.001msec
Valid data range : -1000 to 1000
Standard setting value : 0
This parameter is used to adjust the timing of the feed-forward term of
the velocity command to improve accuracy of the synchronization
with the servo axis being accelerated or decelerated.
Setting -1000 advances the timing by 1 ms, and setting +1000 lags the
timing by 1 ms.
