E.BE

Brake transistor err

Mitsubishi · FR-E800 Variable Frequency Drive

What does E.BE mean?

The inverter output is shut off due to a fault in the brake circuit, typically indicating damage to the brake transistor. This is a critical internal hardware fault requiring immediate attention to prevent further damage.

Complete Troubleshooting Guide

  1. 1

    Reduce the load inertia to minimize demands on the regenerative braking circuit.

  2. 2

    Check that the brake duty cycle is proper for the application, ensuring it does not exceed the inverter's capabilities.

  3. 3

    Replace the entire inverter as this fault often signifies irreparable internal damage.
