Brake Chopper Terminal
The AKT2G-BRC-000-000 EtherCAT Terminal contains high-performance capacitors for stabilizing supply voltages. The AKT2G-BRC-000-000 can be used in conjunction with the AKT2G-SM-L15-000 or AKT2G-SM-L50-000 stepper motor drive terminals. Low internal resistance and high-pulsed current capability enable good buffering in parallel with a power supply unit. Regenerative currents are accommodated preventing over voltages. If the regenerative energy exceeds the capacity of the capacitors, energy can be dissipated via an external braking resistor. The corresponding threshold can be directly parameterized in the KAS Software.
