ATV71 drive is getting brake feedback fault (BRF)
All models, all serial numbers
The brake contact feedback is too one after the command to run is issued.
If BRH b2 is set to 0 the reference is enabled at the end of the brake release time. If BRH b2 is set to 1 then the reference is enabled when the feedback from brake contact enables a logic input and at the end of the brake release time.
- check the feedback circuit and brake logic control.
- check the mechanical state of the brake.
