Fault
Cause
Solution
OH2
Inverter module
overheated
The time of overload running is
too long.
Lower the ambient temperature
EF
External fault
SI external fault input terminals
act
Check the external device input
CE
485
communication
fault
The baud rate setting is
incorrect.
Fault occurs to the
communication wiring.
 Communication address is wrong.
There is strong interference to
the communication.
Set proper baud rate
Check the communication
connection distribution
Set proper communication address.
Chang or replace the connection
distribution or improve the
anti-interference capability.
ItE
Current-detecting
fault
The connection of the control
board is not good
Hall components is broken
The modifying circuit is
abnormal.
Check the connector and re-plug
Change the Hall
Change the main control panel
tE
Motor-autotuning
fault
The motor capacity does not
comply with VFD capability
The rated parameter of the motor
does not set correctly.
The offset between the
parameters from autotune and
the standard parameter is huge
Autotune overtime
Change the VFD mode
Set the rated parameter according to
the motor name plate
Empty the motor load and re-identify
Check the motor connection and set
the parameter.
Check if the upper limit frequency is
above 2/3 of the rated frequency.
EEP
EEPROM
operation fault
Error of controlling the write and
read of the parameters
Damage to EEPROM
Press STOP/RST to reset
Change the main control panel
PIDE
PID feedback
outline fault
PID feedback offline
PID feedback source disappear
Check the PID feedback signal
Check the PID feedback source
bCE
Brake unit fault
Brake circuit fault or damage to
the brake pipes
External brake resistor is
insufficient
Check the brake unit and , change
new brake pipe
Increase the brake resistor
END
Running time
arrival
The actual running time of the
VFD is above the internal setting
running time.
Ask for the supplier and adjust the
setting running time.
OL3
Electrical
overload
 VFD will report overload
pre-alarm based on the set value.
Check the load and the overload
pre-alarm threshold.
PCE
Keypad
The connection of the keypad
Check the keypad wires and ensure
