At the current mode the parameter
is set by the maximum total current of the drive
and is independent of external total current limit or field weakening. The value in
ampere of these limits will not change at field weakening and external total current limit.
The operation of the standardization and the limit modes are described from
on page 459 to
on page 463, whereat lsqLim stands for one of the torque cur-
.

bit 3 = 0).
a) Dependent of the field current (an external total current limit is not assumed).
b) Dependent of external total current limit (field weakening is not assumed)
