Acceleration and deceleration time
(Pr. 7, Pr. 8, Pr. 20, Pr. 21, Pr. 44, Pr. 45, Pr. 147)
Used to set motor acceleration/deceleration time. Set a larger value for a slower speed increase/de-
crease or a smaller value for a faster speed increase/decrease.

The above parameters can be set when Pr. 160 "User group read selection" = 0.
Depends on the Pr. 21 "Acceleration/deceleration time increments" setting. The initial value for
the setting range is "0 to 3600 s" and the setting increments is "0.1 s".
