11.1 Braking Resistors and Braking Units
Inverters ratings 230V 1 ~ 25HP / 460V 1 ~ 40HP / 575V 1~10HP / 690V 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 230V 30HP / 460V 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.
