Fault
code
Fault type
Possible cause
Solution
ETH2
To-ground
short-circuit fault 2
Inverter
output
is
short
connected to the ground;
There is a fault in the current
detection circuit.
Check whether the motor wiring
is normal/the motor is short
circuited to the ground;
Replace the hall component;
Replace
the
main
control
panel/drive board.
dEu
Speed deviation fault
The load is too heavy or
stalled.
Check the load to ensure it is
proper,
and
increase
the
detection time;
Check whether the control
parameters are set properly.
STo
Mal-adjustment fault
SM control parameters are set
incorrectly.
Autotuned parameters are not
accurate.
The inverter is not connected
to the motor.
Check the load and ensure the
load is normal.
Check
whether
control
parameters are set correctly.
Increase the mal-adjustment
detection time.
LL
Electronic underload
fault
The inverter reports underload
pre-alarm according to the
setting.
Check
the
load
and
the
underload pre-alarm points.
E_FAN
Auxiliary fan fault
The fan inverter is in fault.
Check the fault code on the
touch screen.
PSF
Phase sequence
fault
The phase sequence on the
input side of the power is
negative.
Swap any two power input
cables
Communication
interruption
RS485 communication port is
disconnected.
Check
whether
the
communication cable is loose or
dropped.
L-AUP
Low auxiliary
pressure fault
Auxiliary pressure is too low at
start-up.
Check whether P15.06 and
P15.07 are set properly.
HAnd
Handshake failure
The
handshake
process
timeout.
Check whether the handshake
between the Plott controller and
inverter is performed according
to the handshake protocol;
Check whether P15.10 is set
properly.
