What is the function of the EL9576?
The EL9576 is a Brake Chopper Terminal. It contains high-performance capacitors for stabilising supply voltages. It can be used in conjunction with stepper motor terminals, DC motor terminals, and servomotor terminals. It is designed to store return currents, particularly in the context of drive applications, thus preventing overvoltages.
What are the technical specifications of the EL9576?
The EL9576 has a nominal voltage up to 72 V and a capacity of 155 µF. It has a maximum ripple current of 10 A and an internal resistance of less than 5 mΩ. The chopper voltage is adjustable and it has an overvoltage control range typically of 1 V, which is parameterisable by CoE data.
What are the common uses of the EL9576?
The EL9576 is commonly used in conjunction with the EL70x1 stepper motor terminals, the EL73x2 DC motor terminals, and the EL72x1 servomotor terminals. It is particularly useful in drive applications where it helps to prevent overvoltages by storing return currents.
What is the weight and dimensions of the EL9576?
The EL9576 weighs approximately 90 grams. The exact dimensions are not specified in the available datasheets, but it is designed to fit within standard Beckhoff terminal housings.
What are the special features of the EL9576?
The EL9576 has several special features. It has an adjustable threshold and provides diagnostics for temperature on board, over-/undervoltage. If the regenerative energy exceeds the capacity of the capacitors, energy can be dissipated via an external braking resistor.
