** 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 Control Program (parameter selectable function), check with the motor manufacturer if additional
output filters are needed in the applied drive operation range.
Note 1: The abbreviations used in the table are defined below.
