E.BE

Brake transistor err

Mitsubishi Electric · Mitsubishi FR-E800 Variable Frequency Drive

Was bedeutet E.BE ?

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.

Häufige Ursachen

  • Brake transistor failure.
  • The electronic brake is not functioning correctly.
  • Overheating of the brake transistor.
  • Internal fault in the brake control circuit.
  • Short circuit within the brake system.

Reparaturschritte & Checkliste

Klicken Sie auf Schritte, um Ihren Fortschritt zu verfolgen.

  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.
