Possible causes
Solutions
26
Err.26
Cumulative
running time
arrival fault
Cumulative running time arrival
fault
Clear history information by
using initialization function
parameters
27
Err.27
Custom fault 1
Input custom fault 1 signal
through the multi-function
terminal DI
Reset run
28
Err.28
Custom fault 2
Input custom fault 2 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.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
42
Reserve
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
overtemperatur
e 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.

failure
1.Keyboard interface control
board interface；
2.Keyboard or crystal
connector；
3.Control board or keyboard
hardware damage；
4.Keyboard line is too long,
causing the interference.
1．Detection of keyboard
interface, control board interface
is abnorma.
2.Detect keyboard, crystal joints
are abnormal.
3.Replace control board or
keyboard.
4. Consult factory, seek help.
