Current limiting
The motor current can be specified with 1 to 200 % of the
rated motor current depending on the specific application
(see FCT/PlugIn help MTR−DCI).
Positioning axis type DMES−... can carry out reference travel
with the factory−set current limitation (150 % of the rated
motor current). The current limitation need not be modified.

Due to maximum current limitation the value does not rise further.
Tab.5/3: Current limitation
Please note
Please note the following when adapting the current
limitation:
By means of a current limitation, the maximum possible
speed of reference travel will also be reduced. The set
rated speed will therefore, in some cases, no longer be
achieved.
If the drive is arranged vertically, an increase in the
motor current may be necessary. If the motor current is
too low, reference travel cannot be carried out.
