2 = Reducing DC brake current.
The DC braking current can be reduced with the free analog input signal, between
0.15xI
nSV9
and current set with parameter 4.8. See figure 6.2-5.

3 = Reducing acceleration and deceleration times.
The acceleration and deceleration times can be reduced with the free analog input
signal, according to the following formula:
Reduced time =set acc./deceler. time (par. 1.3, 1.4; 4.3, 4.4)
divided by the factor R from figure 6.2-6.
