fault
Cause
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
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
and affected by strong
interference.
There is circuit fault on the
communication of the
keypad and main board.
The connection of the
keypad wires is not good or
broken.
The keypad wire is too long

Commissioning guidelines
Solution
reidentify
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 panel
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.
