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.

Parameter specification in FCT: relative motor current in % of rated current, setting range 1...200.

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.
