Chapter 2 Installation and Wiring
2.2.5 Selection and wiring of regenerative braking resistor (on 0.4 kW to 22 kW models)
The SJ700-2 series inverter models with capacities of 0.4 to 22 kW have an internal regenerative braking
circuit.
Connecting an optional regenerative braking resistor to RB and P terminals increases the regenerative
torque.
