Goodrive300-01A series VFD for air compressor Fault information and troubleshooting
-68-
Fault
code
Fault type
Possible cause
Solution
circuit fault 1
circuited to ground.
• Current detection circuit is
faulty.
• Actual motor power setup
differs sharply from the
VFD power.
is normal/motor is short
circuited to ground.
• Replace the hall.
• Replace main control
board/drive board.
• Reset correct motor
parameters.
ETH2
To-ground short
circuit fault 2
dEu
Speed deviation
fault
Load is too heavy or stall.
• Check the load and ensure
it is normal, increase the
detection time.
• Check whether control
parameters are proper.
STo
Maladjustment fault
• Control parameters of
synchronous motor is set
improperly.
• Autotuning parameters are
inaccurate.
• VFD is not connected to
the motor.
• Check the load and ensure
the load is normal.
• Check whether control
parameters are set
correctly.
• Increase maladjustment
detection time.
LL
Electronic underload
fault
The VFD reports underload
pre-alarm according to the set
value.
Detect the load and underload
pre-alarm threshold.
PSF
Phase sequence
fault
The phase sequence on power
input side is negative.
Swop any two of the power
input cables.
OLF
Current overload of
power-frequency fan
• Rated fan current is set
improperly.
• Fan power is too small.
• Fan stalls.
• Check whether the set
value of P21.00 is the same
with the rated current of the
fan nameplate. whether the
current transformation ratio
P21.01 is the same with
current transformer
nameplate.
• Actually detected fan
current is too large, it is
recommended to increase
the power.
• Check whether the fan
stalls.
SPOF
3PH current
imbalance of
• Phase loss occurs to 3PH
wiring of the fan.
• Check whether the fan is
disconnected or poorly
