Description
Note: If reverse-running delay is 0, the
forward-running delay is used.
P90.28 setting range: 0.00–50.00Hz
P90.29 setting range: 0.000–5.000s
P90.30 setting range: 0.000–10.000s
P90.31 setting range: 0–1
0: Disable
1: Enable the brake current monitoring (and
brake feedback detection).
When the function is disabled, no brake
feedback fault is reported.
After it is enabled, brake status can be
monitored.
In open-loop mode: If the actual brake status is
different from the S-terminal given brake
feedback signal during running or stop, the
brake feedback fault (FAE) is reported after the
brake feedback exception delay P90.32.
In closed-loop mode: During the stop, if a brake
feedback exception occurs, the brake feedback
fault (FAE) is reported after the brake feedback
exception delay P90.32.
During running, if a brake feedback exception
occurs, the current is monitored after the brake
feedback exception delayP90.32. If the present
current is less than the monitored current, it is
considered that the brake is not closed, and the
action specified by P90.34
P90.34=0, the VFD directly reports the brake
feedback fault (FAE). If P90.34=1, the VFD
opens the brake and runs at the speed specified
by0.35, and reports the brake feedback alarm
(A-FA).
