Description
be reported directly after P90.32 brake
feedback abnormal delay if the brake feedback
is abnormal. When running, the current will be
monitored after the P90.32 brake feedback
abnormal delay if the brake feedback is
abnormal. If the present current is less than the
brake monitoring current, it is considered that
the brake is not closed at this time, which will be
carried out according to the action set by
P90.34.
When P90.34=0, the brake feedback fault
(FAE) is reported.
When P90.34=1, open the brake and run at the
speed specified by P90.35, and report the
brake feedback alarm (A-FA) simultaneously.

status monitoring
In closed-loop mode: During running, if a brake
feedback exception occurs, the VFD starts
monitoring current after the brake feedback
exception delay P90.32. If the present current is
greater than the brake monitoring current, the
present actual frequency is checked. If the
actual frequency is lower than the forward
brake frequency during forward rotating or the
actual frequency is lower than the reverse
brake frequency during reverse rotating, it is
considered that the brake has been closed, the
brake feedback fault (FAE) is reported.
