HW control of braking resistor

Was bedeutet E2802 ?

This warning indicates an issue with the hardware control circuit for the braking resistor. This could prevent the braking resistor from dissipating regenerated energy, potentially leading to overvoltage faults.

• Fault in the braking resistor control circuitry within the drive.
• External braking resistor or its wiring is open-circuited or damaged.
• Malfunction of the internal braking transistor or associated components.
• Incorrect parameterization of the braking resistor characteristics.

1. 1

   Inspect the external braking resistor and its connections for damage, loose wiring, or open circuits. Measure its resistance to confirm it's within specifications.

2. 2

   Verify that the braking resistor cable is correctly wired and securely terminated to the drive.

3. 3

   Check the drive's internal diagnostics for specific sub-errors related to the braking circuit.

4. 4

   If possible, test the braking transistor using drive diagnostics or by observing DC bus voltage during regeneration with a known good resistor.
