Chapter 11 Inverter Peripheral devices and Options
11.1 Braking Resistors and Braking Units
Inverters ratings 200V 1 ~ 25HP / 400V 1 ~ 40HP / 575V 1~10HP/600V 15~40HP have a built-in
braking transistor. For applications requiring a greater braking torque an external braking resistor can
be connected to terminals B1 / P and B2; for inverter ratings above 200V 30HP / 400V 50HP/600V
50HP, an external braking unit (connected to - of the inverter) and a braking resistor (connected to
two ends of the detection module
BR - BR) is required.
