6.6 Acceleration and deceleration
6.6.1 Acceleration and deceleration time (Pr. 7, Pr. 8, Pr. 20, Pr. 44, Pr. 45)
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.
The above parameters can be set when Pr. 160 = 0.
