2.2.5 Selection and wiring of regenerative braking resistor (on 5.5 kW to 22 kW models)

The SJ700-2 series inverter models with capacities of 5.5 to 22 kW have an internal regenerative braking circuit.

Connecting an optional regenerative braking resistor to RB and P terminals increases the regenerative torque.
