Brake Control Fault

What does bLF mean?

This fault indicates an issue with the motor's brake control, either because the brake release current was not reached or the brake engage frequency threshold was not properly set while brake control was assigned. This can prevent the motor from starting or stopping correctly, leading to potential mechanical damage or uncontrolled movement.

Complete Troubleshooting Guide

1. 1

   Check the drive-to-motor connection and the motor windings for integrity.

2. 2

   Verify the [Brake release I FW] (Ibr) setting in the [APPLICATION FUNCT.] (FUn-) menu (page 85) to ensure it's appropriate for the brake.

3. 3

   Apply the recommended settings for [Brake engage freq] (bEn) as described on pages 84 and 85 of the manual.
