Max. drive current
Settable limitation of the total current of the drive influences the limitation from the current
torque as well as from the field current.
The maximum total current of the drive is limited by the "Power unit peak current"
:

"Power unit peak current" [
].
19.7
Max. field current amplitude
Display of the maximum amplitude of the field current. The maximum field current for syn-
chronous motors is set via the absolute value of the field current preset value (
).
The maximum field current for asynchronous motors is set via the limitation of flux con-
troller (
The maximum field current amplitude is limited by the maximum total current of the drive
(

Max. torque current
Display of the standardized factor of the maximum torque current in A.

The total current limit of the drive can automatically be reduced furthermore, for ex-
ample by the PU overload monitoring or the phase fail (see "bit bar of external cur-
rent limit"

NOTE!
The amplitude of the field current can be reduced automatically e. g. by the PU over-
load monitoring or phase fail (see "Bit bar of external current limit"
and "Ex-
ternal limiting max. field current amplitude"
), without the parameter value

minimum value between "Max. field current amplitude"
