2.2.5 Selection and wiring of regenerative braking resistor (on 5.5 kW to 30 kW models)
The SJ700B series inverter models with capacities of 5.5 to 30 kW have an internal regenerative braking
circuit.
Connecting an optional regenerative braking resistor to RB and P terminals increases the regenerative
torque.
