69
28
Err.28
Custom fault 2
Input customer fault 1
signal through the multi-
function terminal DI.
Reset run
29
Err.29
Total power-on
time arrival fault
Total power-on time
reaches the set value
Clear history information
by using initialization
function parameters
30
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.
power level of inverter
is too 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
42
Reserved
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
overtemperature
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
reconfirm the correct
motor parameters, focus
