In addition, check whether the baud rate of the control board has been changed. If a hardware reset is required, the operation is as follows:
After powering off, turn the frequency selection switch to the position
to the rated voltage. After the inverter, power off
Then turn the frequency selection switch to the position
In addition, you can check whether the fans are spinning. It may be caused by the fans not spinning
Check the frequency converter and Are the versions of the panel incompatible and were they produced in the same period? You can check the number of the inverter and the year it was produced
Check whether the control power supply is overvoltage
Look at the control card and power board Is there any problem with the communication?
The control card is the board under the operation panel.
First unscrew the plastic screws of the operation panel
Then replace the lower board
Note: This control card is universal. After replacing the board, a fault will be reported when powering on. This fault reported after replacing the board can be resolved by pressing a button.
It is also possible that a few wires between your two boards are loose. After removing the board, check to see if the wires are loose.

Fault R: Solution to RR
First power off, then replace the display module or remove the display module and install it again Power on again and observe if R is displayed, you can rule out the possibility of poor contact between the display module and the control board. Also check whether the baud rate of the control board has been changed. If a hardware reset is required, the operation is as follows:
After powering off , turn the frequency selection switch to the direction
Turn on the rated voltage, power off the inverter
Then turn the frequency selection switch to the direction
In addition, you can check whether the fans are running. , it may be caused by the fan not rotating
Check whether the versions of the inverter and the panel are incompatible and whether they were produced in the same period. You can check the number of the inverter and the year it was produced
Check Check whether the control power supply is over-voltage

Commissioning steps
Schneider inverter debugging steps:
The first step is model confirmation: Confirm whether the model of the inverter is consistent with the model of the purchased inverter. If it is inconsistent, ask the agent to return it.
The second step is transportation confirmation: After opening the package, check whether the inverter is damaged during transportation. If there is any damage, ask the agent to return it.
Step 3: Voltage confirmation: The power supply voltage on site should be within the voltage range accepted by the inverter. Otherwise, all steps below stop.
The fourth step is mechanical installation
The fifth step is the insulation measurement of the motor and frequency converter. Then connect the wiring to the frequency converter: According to the drawing, connect the motor wire to the top, make sure the connection is consistent with the voltage, make sure the power is turned off, connect the main power supply to, connect the control source to the speed reference source. There is a network connection to the network.
Step 6: Power on and debug language modification: After power on, the language selection will be displayed. (This modification is only required for the first time after power-on)
Step 7: Restore factory settings
Step 8: Modify the access level. Electrical maintenance personnel generally set this access level to expert authority.
Step 9: Set the motor parameters such as power, voltage, current, frequency, speed, etc., and perform auto-tuning.
Step 10: Set acceleration and deceleration time: Set a reasonable acceleration and deceleration time.
Step 11: Set the protection parameters, the thermal protection current value of the motor, the current amplitude limit value, etc.
Step 12 Set the control source and frequency source: In the . command, set the channel to start the inverter and the channel to give the frequency. Set the highest frequency, lowest frequency, etc.
The thirteenth step involves the allocation of application functions. Such as braking logic control.
Step 14: Determine the rotation direction of the motor. Set the frequency at a smaller frequency, jog the inverter, and confirm that the rotation direction of the motor is reversed. The parameters can be modified.
Step 15 Record the current value frequency of several frequency bands
