BRAKE CONTROL FAULT

What does bLF mean?

This fault indicates an issue with the brake control system, where the brake release current may not have been reached or the brake engage frequency threshold ([Brake engage freq] (bEn)) is incorrectly set or not assigned despite brake control ([Brake assignment] (bLC)) being active. This can lead to improper motor braking or starting.

• Brake release current not reached
• Brake engage frequency threshold ([Brake engage freq] (bEn)) = [No] (not set) whereas the brake control ([Brake assignment] (bLC)) is assigned
