2. The PID feedback source
disappears.
2. Check the PID feedback
source.
END
Time arrival of
factory setting
The actual running time of the
inverter is above the internal
setting running time.
Ask for the supplier and adjust
the setting running time.
OL3
Electrical overload
The inverter will report
overload pre-alarm according
to the set value.
Check the load and the overload
pre-alarm point.
ETH1
Grounding short
circuit fault 1
The grounding of the inverter
output terminal is short
circuited.
The current detection circuit is
faulty.
The actual motor power
sharply differs from the
inverter power.
Check whether the motor wiring
is proper.
Change the Hall.
Change the main control panel.
Set motor parameters correctly.
ETH2
Grounding short
circuit fault 2
dEu
Velocity deviation
fault
The load is too heavy or
stalled.
1. Check the load and ensure it
is normal. Increase the detection
time.
2. Check whether the control
parameters are normal.
STo
Maladjustment fault
1. The control parameters of
the synchronous motors not
set properly.
2. The autotuning parameter
is not correct.
3. The inverter is not
connected to the motor.
1. Check the load and ensure it
is normal.
2. Check whether the control
parameter is set properly or not.
3. Increase the maladjustment
detection time.
LL
Electronic
underload fault
The inverter will report the
underload pre-alarm
according to the set value.
Check the load and the
underload pre-alarm point.
tSF
Hydraulic probe
damage
Hydraulic probe damage
Change the damaged hydraulic
probe.
