When the value is not zero, current imbalance
detection is enabled. When the 3PH current
max. value divided by the min. value is greater
than this multiple, the Cuu fault is reported.
Setting range of P92.33: 0–1
P92.34 setting range: 100.0%–500.0% (of the
set frequency)
The overspeed protection function can be
enabled in open/closed loop vector mode, but in
closed loop mode, the actual speed feedback
comes from the encoder. When the overspeed
protection function is enabled, the overspeed
protection threshold of VFD is calculated, which
is Set frequency * Overspeed protection
percentage. When the VFD runs, if the actual
frequency is greater than or equal to the
protection threshold, the VFD considers it is in
the overspeed state, reports an overspeed fault,
and stops running.
Setting range of P92.35: 0–1
P92.36 setting range: 0.0 –250.0% (100.0%
corresponding to the motor rated current)
Setting range of P92.37: 0.00–10.00s
The stalling protection function is valid only in
closed-loop vector mode, but in closed loop
mode, the actual speed feedback comes from
the encoder. When the stalling protection
function is enabled, if the target frequency is
greater than 0.50Hz during VFD running, the
VFD starts delay timing. When the preset time
is reached, if the actual running frequency is
still lower than 0.50Hz, and the output current is
greater than the stalling protection current
value, which lasts 20ms, the VFD considers
