Description
P92.33 setting range: 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.
P92.35 setting range: 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 can be enabled
in open/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 stalling
occurs, and then it reports the fault and stops
running.
