Selection Tables

The SJ300 Series 200V and 400V class inverter models in the 1/2 to 15 hp range have internal braking units. Additional stopping torque is available by adding external resistors. The required braking torque depends on your particular application. Other tables in this section will help you choose the proper resistor.
