Remark:
Values 2 to 43 are only displayed when a pole position search is active (Actual Operating

= -1).
For the other drive operating modes, the status is either 0 or 1.
19.5
Max. drive current actual value
Shows the currently effective limit of the apparent current. It influences the limit of the cur-
rent torque as well as of the field current. The parameter accords to the minimum value
between the "maximum total current of the drive"

19.6
Max. drive current
Settable limitation of the apparent 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"
