1
Reduces motor current limit
(ID107)
This signal will adjust the maximum motor current between
0 and max. limit set with ID107. See Fig. 50.
2
Reduces DC braking current DC braking current can be reduced with the free analogue
input signal between zero current and the current set with
the parameter ID507. See Fig. 51.
3
Reduces acceleration and
deceleration times
Acceleration and deceleration times can be reduced with the
free analogue input signal according to the following formu-
las: Reduced time = set acc./deceler. time (parameters
ID103, ID104; ID502, ID503) divided by the factor R in Fig. 52.
4
Reduces torque supervision
limit
Set supervision limit can be reduced with the free analogue
input signal between 0 and set torque limit supervision value
(ID349), see Fig. 53.
