Motor
parameter auto
tunning fault
1.the motor parameters was
not set according to the
nameplate
2.the identification process of
parameter is timeout
1.correctly set motor
parameter according to the
nameplate
2.check the lead wire from
the inverter to the motor
1.the encoder is damaged
2.PG card is abnormal
3.the encoder model does not
match
4.the encoder connection has
error
1.replace the encoder
2.replace the PG card
3.correctly set the encoder
model according to the
Actual conditions
4.eliminate the line fault
EEPROM read
and write fault
Replace the main control
panel
1.overvoltage
2.overcurrent
1.eliminate overvoltage
fault
2.eliminate overcurrent
fault
Short-circuit to
ground fault
Replace the cable or motor

Clear history information
by using initialization

Input custom fault 1 signal
through the multi-function
terminal DI
Input custom fault 2 signal
through the multi-function
terminal DI
Total power-on
time arrival
fault
Total power-on time reaches
the set value
Clear history information
by using initialization
function parameters
The inverter running current is
less than F8.31
Confirm whether the load
is removed or not or the
settings for
parameter(F8.31, F8.32)
accord with the Actual
operating conditions
PID feedback
loss when
running fault
PID feedback is less than the
set value of E2.11
Check PID feedback
signal or set E2.11 to an
appropriate value
Quick current
limiting
fault
1.whether the load is too large
