Brake Resistor Overheat

What does 7112 mean?

The brake resistor has overloaded and is experiencing excessive temperature. This condition indicates that the resistor is dissipating too much energy, potentially due to an incorrect braking cycle or excessive supply voltage, posing a risk of damage to the resistor and surrounding components.

Complete Troubleshooting Guide

1. 1

   Allow the brake resistor to cool down completely before proceeding.

2. 2

   Check the parameter settings for the resistor overload protection function (refer to parameter group 27 BRAKE CHOPPER).

3. 3

   Verify that the braking cycle and frequency meet the allowed limits for the installed resistor and application.

4. 4

   Inspect the drive's supply AC voltage to ensure it is not excessively high, contributing to greater braking energy.
