Additional measures have to taken upon commissioning to ensure smooth
functioning - irrespective of the storage time which may be longer than the
warranty period of our products. Warranty extension is not a consequence.

●
●
●
Visual inspection of all parts to be damage-free
●
●
●
Resurface the holding brake
●
●
Check the electric contacts to verify that they are free from corro‐
sion
●
●
Let the motor run in without load for one hour at 800 ... 1000 rpm.
●
●
Measure insulation resistance. Dry the winding at a value of <
1kOhm per volt rated voltage.
●
Replace bearings
●
Replace encoders

Operation on foreign converters
Principally, operating MS2E motors on foreign converters is possible, but the
following requirements and limitations on foreign converters must be ob‐
served.
Danger of explosion or material damage due
to overload!
WARNING
Observe the following requirements for safe motor operation on foreign con‐
verters. Connection of all necessary sensors and additional devices for a safe
operation and their evaluation lies in the sole responsibility of the plant manu‐
facturer or operator.
Requirements on the power output stage
●
Converter with pulse width modulation
●
Pulse frequency 4 kHz …16 kHz
Voltage load of the motor
During converter operation, the motor underlies a higher voltage load (insula‐
tion system, bearing) than on a sinusoidal source voltage only.
Standard values for peak voltage and rate of rise of voltage:
38/65
