ABB ACS800 inverter IGBT module

Braking resistor

Configuration and selection: Transmission units with external specifications of R2 and R3 include built-in brake choppers, R4 and larger brake choppers are optional (model+D150), and resistors are additional components; When selecting the transmission unit/chopper/resistor, it is necessary to calculate the braking power to ensure that the resistor resistance and heat loss capacity meet the requirements.

Installation and wiring: All resistors must be installed outside the transmission unit module, with flame-retardant materials nearby. They should be connected using cables of the same model as the input cables of the transmission unit, with a maximum allowable length of 10m. The shielding layer should be properly grounded.

Protection and debugging: It is recommended to configure the main circuit contactor for external specifications R2~R5, and whether R6, R7, and R8 are needed depends on the selection situation; A thermal switch should be installed inside the braking resistor and connected to the digital input port as an external fault interlock signal; Activate the brake chopper function during debugging, turn off the overvoltage control function, and check the resistance value setting.
