** 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.
