The EL9576 EtherCAT Terminal contains high-performance capacitors for stabilizing supply voltages. The EL9576 can be used in conjunction with the EL70x1 stepper motor terminals, the EL73x2 DC motor terminals and the EL72x1 servomotor terminals. 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, thus preventing overvoltages. 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 TwinCAT System Manager.
