1) If the intermediate DC circuit voltage of the drive is increased from the nominal level due to long term resistor braking
cycles, check with the motor manufacturer if additional output filters are needed in the applied drive operation range.
The abbreviations used in the tables are defined below.

N
Û Peak line-to-line voltage at motor terminals which the motor insulation must withstand
LL
