2.2.5 Selection and wiring of regenerative braking resistor (on 11 kW to 30 kW models)
The L700 series inverter models with capacities of 11 to 30 kW have an internal regenerative braking
circuit.
Connecting an optional regenerative braking resistor to RB and P terminals increases the regenerative
torque.
