Lenze E94AMHE0074 Central control module

Product Description

Lenze braking modules are electronic components designed to dissipate the energy generated during the braking process of AC motors driven by variable frequency drives (VFDs). When a motor is decelerated 

rapidly, the kinetic energy is converted into electrical energy that is fed back into the VFD. To prevent damage to the VFD, this excess energy must be safely dissipated. Lenze braking modules provide a controlled 

and efficient way to absorb this energy.

Key Features and Specifications

• Voltage and Current Ratings: Vary depending on the specific model but typically range from several hundred volts to thousands of volts and several amperes to tens of amperes.

• Cooling: Forced air or liquid cooling options are available to dissipate heat effectively.

• Mounting: Can be panel-mounted or mounted directly to the VFD.

• Communication: May have built-in communication interfaces for monitoring and control.

• Safety Features: Overcurrent, overvoltage, and thermal protection.

Advantages

• Protects VFD: Prevents damage to the VFD by safely dissipating excess energy.

• Improved Performance: Enhances the braking performance of the motor.

• Reduced Maintenance: Robust design and high reliability.

• Customizable: Available in various configurations to meet specific application requirements.

• Safety: Built-in safety features ensure safe operation.

Precautions

• Sizing: The braking module must be sized correctly to handle the expected braking energy.

• Cooling: Ensure adequate cooling to prevent overheating.

• Mounting: Follow the manufacturer's instructions for proper mounting.

• Wiring: Correct wiring is essential to prevent electrical hazards.

• Maintenance: Regular inspection and maintenance are recommended.

Applications

Lenze braking modules are used in a wide range of applications, including:

• Material Handling: Conveyors, cranes, and hoists.

• Packaging: Packaging machines and filling systems.

• Textile: Winding machines and textile processing equipment.

• Automotive: Assembly lines and testing equipment.

• Machine Tools: Lathes, milling machines, and drilling machines.

How Lenze Braking Modules Work

When a motor is decelerated, the VFD operates in regenerative mode, converting the kinetic energy into electrical energy. This energy is then fed back into the braking module. The braking module dissipates 

the energy through a resistive element, converting it into heat.
