The Beckhoff EL9576 is a high-performance brake chopper terminal designed to stabilize supply voltages. It can be used in conjunction with EL70x1 stepper motor terminals, EL73x2 DC motor terminals, and EL72x1 servomotor terminals. The EL9576 features low internal resistance and high-pulsed current capability, enabling good buffering in parallel with a power supply unit. It stores return currents, 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 parameterised in the TwinCAT System Manager.
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.
- The Beckhoff EL9576 is commonly used in conjunction with EL70x1 stepper motor terminals, EL73x2 DC motor terminals, and EL72x1 servomotor terminals for stabilizing supply voltages.
- It is often utilized in drive applications to store return currents, thus preventing overvoltages.
- The part is used to dissipate excess regenerative energy via an external braking resistor when the capacity of the capacitors is exceeded.
- The EL9576 is also used in systems where adjustable chopper voltage is required.
- It is commonly used in applications where a high-pulsed current capability and low internal resistance are needed for good buffering in parallel with a power supply unit.
- The part is often used in systems that require overvoltage control range and ballast resistor clock rate adjustments.
- The EL9576 is typically used in environments that require electrical isolation between E-bus and field potential.
- It is also used in systems that require on-board temperature diagnostics and over-/undervoltage detection.
