This signal will adjust the maximum motor current between
0 and max. limit set with ID107. See Fig. 50.
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.
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.
Set supervision limit can be reduced with the free analogue
input signal between 0 and set torque limit supervision value
(ID349), see Fig. 53.
