error
Possible cause
The connection of the control
board is not good;
Assistant power is bad;
Hall components is broken;
The magnifying circuit is
abnormal
The motor capacity does not
match with VFD capacity;
The rated parameter of the
motor is set improperly;
The deviation between the
parameters from autotune and
the standard parameter is huge;
Autotune overtime
Error occurred to R/W of the
control parameter;
EEPROM is damaged
PID feedback offline;
PID feedback source disappear
Braking circuit fault or damage
to the brake pipes;
The external brake resistor is
not sufficient
The actual running time of the
VFD is larger than the internal
setting running time
The keypad is not in good
connection or offline;
The keypad cable is too long
and there is strong interference;
Part of the communication
circuits of the keypad or main
board have fault
Check the connector and plug
wire again;
Change the hall;
Change the main control panel
Change the VFD model;
Set the rated parameter
according to the motor
nameplate;
Empty the motor load;
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
wire;
Check the PID feedback source
Check the brake unit and
change to new brake pipe;
Increase the brake resistor
Ask for the supplier and adjust
the setting running time
Check the keypad cable and
ensure it is normal;
Check the environment and
eliminate the interference
source;
Change hardware and ask for
maintenance service
