Err.30
Load drop fault
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
31
Err.31
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
40
Err.40
Quick current
limiting
fault
1.Whether the load is too large or
the motor stall occurs
2.The type selection of inverter is
small
1.Reduce the load and
check the motor and its
mechanical conditions
2.Choose the inverter with
large power level
41
Err.41
Switch motor
when running
fault
Change current motor through the
terminal when the inverter is
running
Switch motor after the
inverter stops
43
Err.43
Motor over
speed fault
1.The parameter was not identified
2.The setting for encoder
parameters is incorrect
3.The setting for motor overspeed
detection parameter(F8.13, F8.14)
is unreasonable.
1.Perform identification
for the motor parameters
2.Correctly set encoder
parameters
3.Reasonably set the
detection parameters
45
Err.45
Motor over
temperature
fault
1.The wiring of temperature sensor
is loose
2.The motor temperature is too
high
1.Detect the wiring of
temperature sensor wiring
and eliminate fault.
2.Decrease carrier
frequency or take other
cooling measures to cool
motor
51
Err.51
Initial position
error
The deviation between the motor
parameters and the actual
parameters is too large
Reconfirm the correct
motor parameters, focus
on whether the rated
current is set to too small
