broken;
The modifying circuit is
abnormal
The motor capacity does
not comply with the inverter
capacity;
The rated parameter of the
motor does not set
correctly;
fault
The offset between the
parameters from autotune
and the standard parameter
is huge;
Autotune overtime
Error of controlling the write
and read of the parameters
fault
Damage to EEPROM
Braking circuit fault or
damage to the braking
pipes;
The external braking
resistor is not sufficient
The actual running time of
the inverter is above the
internal setting running time
The inverter will report
overload pre-alarm
according to the set value
The connection of the
keypad wires is not good or
broken;
The keypad wire is too long
Keypad
and affected by strong
interference;
There is circuit fault on the
communication of the
keypad and main board
Cause

Fault tracking
Solution
Change the main control
board
Change the inverter model;
Set the rated parameter
according to the motor name
plate;
Empty the motor load and
reindentify;
Check the motor connection
and set the parameter;
Check if the upper limit
frequency is above 2/3 of the
rated frequency
Press STOP/RST to reset;
Change the main control
board
Check the braking unit and ,
change new braking pipe;
Increase the braking resistor
Ask for the supplier and
adjust the setting running time
Check the load and the
overload pre-alarm point
Check the keypad wires and
ensure whether there is
mistake;
Check the environment and
avoid the interference source;
Change the hardware and
ask for service
