Brake chopper error

What does 04 mean?

An error has occurred in the internal brake chopper circuit of the MOVIMOT drive. This circuit is responsible for dissipating regenerative energy generated by the motor during deceleration.

• Internal hardware fault of the brake chopper circuit

Click steps to track your progress.

1. 1

   Verify the drive's deceleration ramp times and braking parameters are correctly configured for the application load and inertia.

2. 2

   Inspect any externally connected braking resistor and its associated cabling for proper connection, damage, and correct resistance value (if applicable).

3. 3

   Measure the DC bus voltage during operation, especially during deceleration, to check for overvoltage conditions.

4. 4

   Check the drive's diagnostic logs or status screens for additional related fault codes or warnings.
