18.5.16 Field weakening factor k
f
> as winding ratio q
Warning!
The field weakening factor k
f
is xxx.
The winding ratio q is yyy.
For an optimally adapted drive, k
f
must be < q.
Cause Effects Possible remedies
The field weakening factor k
f
entered
is greater than the winding ratio q.
The drive solution is not optimal with
regard to the utilisation of the
torque-speed requirement.
Check the torque-speed requirement
in the M-n characteristic of the mo-
tor, or set k
f
<q.
