Toshiba TOSVERT VF-PS1 Instruction Manual page 105

All 200V VF-PS1 and 400V VF-PS1 with ratings of up to 220kW have built-in dynamic braking transistor 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 250kW or more, connect a resistor, as shown in
Figure c).
