Fault
code
Fault type Possible cause Solution
transients
OL2 [12] VFD overload

Acceleration is too fast.

The motor is restarted
during rotating.

The grid voltage is too low.

The load is too large.

Increase acceleration time.

Restart the motor after stop.

Check grid voltage.

Adopt the VFD with a larger
power.

Select a proper motor.
SPI
[13] Phase loss on
input side

Phase loss or fluctuation
occurs to input R, S and T.

Check input power.

Check installation wiring.
SPO
[14] Phase loss on
output side

Phase loss output occurs
to U, V and W (or serious
3PH imbalance occurs to
the load).

Check the output wiring.

Check the motor and cable.
OH1
[15] Overheat of
rectifier module

Air duct blocked or fan
damaged.

Ambient temperature is too
high.

Long-time overload
running.

Ventilate the air duct or
replace the fan.

Lower down the ambient
temperature.
OH2
[16] Overheat of
inverter module
EF [17] External fault

S external fault input
terminal acts.

Check external equipment
input.
CE
[18] 485
communication fault

Baud rate is set improperly.

Communication line fault.

Communication address
error.

Communication suffers
strong interference.

Set proper baud rate.

Check the wiring of
communication interface.

Check the wiring of
communication interfaces.

Set correct communication
address.

Replace or change the
wiring to improve
anti-interference capacity.
ItE
[19] Current
detection fault

Poor contact of controller
board connector.

Hall components are
damaged.

Amplifying circuit is
abnormal.

Check the connector and
re-plug wires.

Replace the hall.

Replace the main control
board.
tE
[20] Motor
autotuning fault

Motor capacity does not
match VFD capacity.

Change the VFD model.

Set motor type and
