Connecting an external braking resistor optional | Toshiba VF-AS1

E6581301

All 200V VF-AS1 and 400V VF-AS1 with ratings of up to 160kW have built-in dynamic braking transistors 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).
