What can cause an brF or brake feedback fault on the ATV630 or ATV930 drives?
Issue:
ATV630 and ATV930 showing brF or brake feedback fault.
Product Line:
ATV630 or ATV930 drives
Environment:
All
Cause:
The monitoring of the brake (assign the braking contact to a logic input) does not
match the braking command.
Resolution:
brake feedback and the control circuit.
• Check the mechanical state of the brake.
• Check parameter BCI → brake contact input
• Check parameter BLC → brake assignment.
• Check parameter BRT → brake release time.
• Check parameter BET → brake engage time.
