How to choose the inverter for the brake?

Specific procedures and requirements for installing a frequency converter on a brake.

Basic requirements for selecting a motor with a brake when supporting a frequency converter. A motor with a brake must have a regenerative braking signal processing unit or an additional regenerative braking signal processing unit as an option.

At the same time, in order to maintain the positioning of the motor, emergency stop and stop, generally a motor with a mechanical brake should be used.

Requirements for the connection of brake power to the frequency conversion speed regulation system:

The brake power must be connected to the input of the inverter, because the output voltage of the inverter is low voltage at low speed, so the attraction of the electromagnet will be weakened, and the brake will be released.

Therefore, the voltage of the brake cannot be the same as that of the motor.
