EL9570 - Introduction and technical data Buffer capacitor terminal
Fig.52: EL9570The EL9570 EtherCAT Terminal contains high-performance capacitors for stabilizing supply voltages.
The EL9570 can be used, for example, in conjunction with the EL7041 stepper motor terminal, the EL7342 DC motor terminal or the EL7201 servomotor terminal.
Low internal resistance and high pulse current capability enable good buffering in parallel with a power supply unit. Reverse 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 braking resistor.
