Acceleration/deceleration 
pattern and backlash measures
Pr.29, Pr.140 to Pr.143
Used to set motor acceleration/deceleration time.
Set a larger value for a slower speed increase/decrease or a smaller value for a faster speed increase/
decrease.
For the acceleration time at automatic restart after instantaneous power failure, refer to Pr. 611  Acceleration
time at a restart
 (page 152).
