parameters autotuning 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 source
disappear
Braking circuit fault or
damage to the braking pipes
The external braking
resistor is not sufficient
The output of the VFD is
fault 1
short circuited with the
ground
There is fault in the current
detection circuit
The actual motor power
fault 2
sharply differs from the VFD
power.
The load is too heavy or
fault
stalled
The control parameters of
the synchronous motors not
set properly
The autotune parameter is
not right
The VFD is not connected
to the motor
The actual running time of
the VFD is above the internal
setting running time
Possible cause

Fault tracking
What to do
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
Check the PID feedback
source
Check the braking unit and
change new braking pipe
Increase the braking
resistor
Check if the connection of
the motor is normal or not
Change the hall
Change the main control
panel
Set motor parameters
correctly.
Check the load and ensure
it is normal
Increase the detection time
Check whether the control
parameters are normal
Check the load and ensure
it is normal
Check whether the control
parameter is set properly or
not
Increase the maladjustment
detection time
Ask for the supplier and
adjust the setting running
time
