This function allows the changing of the current limits “
In use Tcur lim + / -
“ according to the motor speed,
through a curve composed by six setpoints. The “
I/n speed
” and “
I/n lim 0,1,2,3,4
”are the parameters that al
-
low to define the curve.

“
I/n speed
” parameter defines the speed range in which the current
limits are kept at the value of “
I/n lim 0
”. The speed range included between “
I/n speed
” and the 100% of the
max. speed will be divided internally in four equal segments, at the ends of which the current limits “
I/n lim
0,1,2,3,4
” are associated. The set values must decrease , starting from “
I/n lim 0
” up to “
I/n lim 4
”.

I/n lim 0
Current limit of the I/n curve that operates constantly up to the speed set by the “
I/n
speed
” parameter.
I/n lim 1
First current limit which states the Taper current curve construction.
I/n lim 2
Second current limit which states the curve construction.
I/n lim 3
Third current limit which states the curve construction.
I/n lim 4
Fourth current limit which states the curve construction.
I/n speed
Threshold speed at which torque reduction starts.
