1. Question: The fan blows air in reverse direction
Answer: Adjust the motor wire (the motor has a total of 4 wires GND. U, V, W, and can be switched at the connection point of the fan by changing the position of 2 wires of U, V, W)
Adjust the P09 parameter of the frequency converter and modify the code with content 0 and 1
2. Question: Err01
Short circuit in the output circuit of the frequency converter
Loose internal wires of the frequency converter
Answer: Eliminate peripheral faults (surrounding environment)
Check if the air duct is blocked, if the fan is working properly, and eliminate any problems
Check if all connecting wires are loose and securely fastened
3. Question: Err02
The output circuit of the frequency converter is grounded or short circuited
The acceleration time is too short
Low voltage
Sudden overload during acceleration process
Answer: Increase acceleration time
Adjust the voltage to the normal range
Choose to start with speed tracking or wait for the motor to stop before starting again
4. Question: Err09
The input voltage of the frequency converter is not within the range required by the specifications
Abnormal bus voltage
Abnormal control board
Answer: Reset fault (press the reset button to reset the frequency converter or restart the frequency converter)
Adjust the voltage to the normal range
5. Question: Err10
Answer: Check if there are any foreign objects blocking the suction end of the fan
Replace the frequency converter
6. Question: Err11
Is the load too large or is there motor stalling
Answer: Reduce the load and check the motor and mechanical condition
7. Question: Err12
The three-phase input power supply is abnormal
Driver board abnormality
Main control board abnormality
Abnormal lightning protection board
Answer: Check and eliminate problems in the peripheral circuits
Contact the manufacturer for technical support
8. Question: Err13
The lead from the frequency converter to the motor is abnormal
The three-phase output of the frequency converter is unbalanced during the operation of the motor
Answer: Eliminate peripheral faults (surrounding environment)
Check if the three-phase winding (U, V, W) of the motor is normal and eliminate the fault
Question: Err14
The ambient temperature is too high
Air duct blockage
Fan damaged
Answer: Reduce the ambient temperature
Clean the air duct
Replace the fan
10. Question: Err17
Driver board and power supply are abnormal
The contactor is not functioning properly
Answer: Replace the driver board or power board
Replace the contactor
11. Question: Err10
Answer: Check if there are any foreign objects blocking the suction end of the fan
Replace the frequency converter
