Cause : Brake fault comes when fault has arisen on the brake. The text show in the display indicates a fault message. The figure after the text is the fault code that can be seen in the fault log, parameter 615.

Brake check failed (BRAKE CHECK FAILED) [0]- The brake check carried out during power-up indicates that the brake has been disconnected. Check whether the brake has been connected correctly and that it has not been disconnected.

Brake resistor short-circuited (BRAKE RESISTOR FAULT) [1]- The brake output has short-circuited. Replace the brake resistor.

Brake IGBT short-circuited (BRAKE IGBT FAULT) [2]- The brake IGBT has short-circuited. This fault means that the unit is not able to stop the brake and that, consequently, the resistor is constant being energized.
