EL9576 - Introduction
Brake chopper terminal
The EL9576 EtherCAT Terminal contains high-performance capacitors for stabilizing supply voltages.
The EL9576 can be used, for example, in conjunction with the EL70x1 stepper motor terminal, the EL73x2 DC motor terminal or the EL72x1 servo motor terminal. Low internal resistance and high pulsed current capability enable good buffering in parallel with a power supply unit.
Return currents are stored, particularly in the context of drive applications, thereby preventing overvoltages. If the recovery energy exceeds the capacity of the capacitors, energy can be dissipated via an external ballast resistor (e.g. Beckhoff ZB8110). The switching threshold for this can be parameterized via the TwinCAT System Manager.
