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
Err.42
Too large speed
deviation fault
1. The setting for Too Large Speed Deviation
parameters(F8.15, F8.16) is unreasonable.
2. The setting for encoder parameters is incorrect
3. The parameter was not identified
1. Reasonably set the detection parameters
2. Correctly set encoder parameters
3. Perform identification for the motor parameters
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 and the
actual parameters is too large
Reconfirm the correct motor parameters, focus on
whether the rated current is set to too small.

COF
Communication
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.
