Brake Resistor Overheat

What does 7112 mean?

The brake resistor is overloaded, leading to excessive temperature. This can occur if the braking cycle is too demanding, if the supply AC voltage to the drive is excessive, or if the resistor overload protection is misconfigured, risking damage to the resistor.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify that the braking cycle (duration, frequency, energy dissipation) meets the allowed operational limits for the installed resistor.

2. 4

   Measure the drive's AC supply voltage to ensure it is within specified limits and not excessively high.
