** 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 or by the IGBT supply unit control program (parameter selectable function), check with the
motor manufacturer if additional output filters are needed in the applied drive operation range.
