Brake Check Fault

What does 1 mean?

This fault indicates an issue during the drive's internal brake check procedure, suggesting a problem with the braking unit or its connection. This could prevent the drive from starting or safely stopping the motor, posing a risk of uncontrolled movement if the braking system is compromised.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Inspect the braking chopper unit (if external) for signs of damage or incorrect operation.

2. 4

   Temporarily disable the brake check function (if configurable) for diagnostic purposes, but only if safe to do so.

3. 5

   If the issue persists, consider replacing the braking resistor or the internal/external braking chopper.
