** For motors manufactured before 1.1.1998, check for additional instructions with the motor manufacturer.
*** If the intermediate DC circuit voltage of the drive is increased from the nominal level by resistor braking , check
with the motor manufacturer if additional output filters are needed in the applied drive operation range.
