communication;
Communication interrupt for a long
time
Set proper baud rate;
Press STOP/RST to reset and ask
for service;
Check the communication
connection distribution

tE
Motor autotuning
fault
The motor capacity does not comply
with the VFD capacity;
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 model;
Set the rated parameter according
to the motor name plate;
Empty the motor load and
reidentify;
Check the motor connection and
set the parameter
EEP
EEPROM
operation fault
Error of controlling the write and read
of the parameters;
Damage to EEPROM
Press STOP/RST to reset and ask
for service;
Ask for service
PIDE
PID feedback
outline fault
PID feedback offline;
PID feedback source disappear
Check the PID feedback signal;
Check the PID feedback source
bCE
Braking unit fault
Braking circuit fault or damage to the
braking pipes;
The external braking resistor is not
sufficient
Check the braking unit and change
new braking pipe;
Increase the braking 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
The VFD will report overload
pre-alarm according to the set value.
Check the load and the overload
pre-alarm point.
PCE
Keypad
communication
fault
The connection of the keypad wires is
not good or broken;
The keypad wire is too long and
affected by strong interference;
There is circuit fault on the
Check the keypad wires and
ensure whether there is mistake;
Check the environment and avoid
the interference source;
Change the hardware and ask for
