Brake Chopper
SEW Eurodrive · MOVIDRIVE compact System (MCF/MCV/MCS4_A)
¿Qué significa 04 ?
Immediate switch-off indicating an issue with the braking system, such as excessive regenerative power, an interrupted braking resistor circuit, a short circuit in the braking resistor circuit, a braking resistor with too high resistance, or a defective brake chopper. A ground fault could also be a contributing factor.
Causas comunes
- The brake chopper circuit is malfunctioning or not engaging correctly.
- Issue with the braking resistor or its connection.
- Over-braking or regenerative energy exceeding chopper capacity.
Pasos de reparación & Lista de verificación

- 1
Extend the deceleration ramps (e.g., in parameters P501 or P503) to manage regenerative power.
- 2
Check the supply cable connections to the braking resistor for continuity and correct wiring.
- 3
Verify the technical data (e.g., resistance value) of the braking resistor matches specifications.
- 4
Replace the MOVIDRIVE unit if the internal brake chopper is determined to be defective.
- 5
Check for any ground faults within the braking resistor circuit or associated wiring.
