failure
Possible cause
SI external fault input
terminals acts.
Baud rate is set
improperly.
Communication line
fault.
Communication address
error.
Communication suffers
from strong interference.
R/W error occurred to
the control parameters.
EEPROM is damaged.
PID feedback offline
PID feedback source
disappears.
The actual running time
of the VFD is larger than
the set running time.
The VFD releases
overload pre-alarm
based on the set value.
The VFD releases
underload pre-alarm
based on the set value.
Possible cause
The system is powered
off or the bus voltage is
too low.

Solution

Check the external
device input.

Set proper baud rate.

Check the wiring of
communication
interfaces.

Set proper
communication
address.

Replace or change the
wiring to enhance
anti-interference
capacity.

Press STOP/RST to
reset.

Replace the main
control board.

Check PID feedback
signal wires.

Check PID feedback
source.

Ask help
supplier, and
the set running time

Check the load and
overload
threshold.

Check the load and
underload
threshold.
Solution
