Product Description:
The EL9576 brake chopper terminal is a Beckhoff product that is designed for industrial automation. Beckhoff is recognized for its extensive selection of robotics and drive technology options that are compatible with control systems. The brake chopper terminal is designed to keep supply levels stable and handle the drive systems' regenerative energy.
The EL9576 brake chopper terminal has a technology that enables it to operate at a minimum voltage of 72 V. The connector has a 155 µF capacitor. It can handle a ripple current of up to 10 A and has an internal resistance of less than 5 mΩ. The voltage of the chopper can be changed, and a 10 Ω braking resistor with a power limit of 100 W is usually best for most uses. The overvoltage control range is usually 1 V, and CoE data can be used to set the parameters. The braking resistor clock rate depends on the load and can go up to 100 µs. It uses a two-point control method. Between the E-bus and the field potential, there is 1500 V of electrical separation. The brake chopper terminal can be connected to servomotor, DC, or stepper terminals. It also has an adjustable cutoff for precise energy management. The item is meant to handle return currents and avoid overvoltages by releasing extra energy through an external brake resistor when the capacitor's capacity is reached.
The EL9576 brake chopper terminal has extra features that help it work efficiently and safely. The terminal is about 90 grams heavy and can work in temperatures ranging from 0 to +55°C. It can also be stored in temperatures ranging from -25°C to +85°C. The humidity level can go up to 95% without condensation, and it meets the standards for EMC protection and emissions EN 61000-6-2 and EN 61000-6-4.
Frequently Asked Questions about EL9576:
Q: Why does EL9576 have a 155 µF capacitor?
A: The 155 µF capacitor in the brake chopper terminal provides energy buffering that helps stabilize supply voltages and absorb regenerative currents in drive systems.
Q: Does EL9576 support adjustable chopper voltage?
A: Yes, the brake chopper terminal features an adjustable chopper voltage that allows precise energy management and adaptation to different drive requirements.
Q: Why is the internal resistance of EL9576 below 5 mΩ?
A: A low internal resistance below 5 mΩ ensures efficient energy transfer that minimizes losses and supports high ripple current capability.
Q: How does EL9576 handle overvoltage events?
A: The brake chopper terminal uses an external braking resistor that dissipates excess energy when the voltage threshold is exceeded, preventing overvoltage conditions.
Q: Do the electrical isolation features of EL9576 matter?
A: Electrical isolation of 1500 V between E-bus and field potential protects sensitive electronics and ensures safe operation in automation systems.
