Cause
parameters from autotune and
the standard parameter is huge
Autotune overtime
Error of controlling the write
and read of the parameters
Damage to EEPROM
PID feedback offline
PID feedback
disappear
Braking circuit fault or damage
to the braking pipes
The external braking resistor
is not sufficient
The actual running time of the
VFD is above the internal
setting running time.
The VFD 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
interference.
There is circuit fault on the
communication of the keypad
and main board.

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 PID feedback signal
source
Check the PID feedback source
Check
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.
strong Check the environment and avoid
the interference source.
