Brake Transistor Alarm Detection
Mitsubishi · D700 Inverter
What does E.BE mean?
This fault indicates that the brake transistor has detected an alarm condition, typically due to excessive regenerative energy from the motor. This usually happens during rapid deceleration or when driving high-inertia loads, leading to overheating of the braking components. Continuous overheating can damage the inverter's internal brake circuit and external brake resistor.
Additional Steps
Steps 1–2 are listed in Priority Fix.
- 3
Verify that the installed brake resistor is correctly sized (resistance and power rating) for the application's regenerative energy requirements and inspect it for damage.
- 4
If the fault persists after these steps, the inverter's internal brake circuit may require replacement; contact a sales representative for assistance.
