Toshiba TOSVERT VF-AS1 Instruction Manual page 102

All 200V VF-AS1 and 400V VF-AS1 with ratings of up to 160kW have built-in dynamic braking resistors as standard
equipment. If the rating of your inverter falls within this range, connect the resistor, as shown in Figure a) below or
Figure b) on the next page. If your inverter has a power rating of 200kW or more, connect a resistor, as shown in
Figure c).
