First, the process of inverter rehabilitation factory value
1. Study the manual and find the corresponding function number, or key combination.
2. Confirm that the parameters can be corrected (sometimes the inverter will set the parameter to write the protection function in order to prevent the parameters from being changed randomly, and the code must be bound to enter the correction), and the inverter cannot correct the parameters when there is a starting signal input or in the process of running (dragging the motor).
3. Remove the output motor line of the inverter, turn on the power supply of the inverter, and correct the beginning.
Second, the inverter rehabilitation factory value method
There are two ways to operate the factory value of rehabilitation, and different inverter methods are different.
a. After the panel key combination or the process of certain operation.
b. After setting some parameters.
For example, Danfoss inverter, after holding down three key combinations at the same time when the inverter is powered off, then turning on the power switch of the inverter, and then releasing the hand, the inverter will recover the factory parameters. Mitsubishi inverter, panel control according to the certain operation process, select the form, switch parameters, and then press and hold the SET button to restore the factory value; It can also be done by correcting the value of a parameter.
Set the inverter parameters in P5.0.19 (parameter initialization) = 9 or 19. If it is set to 9, the factory parameters will be restored, but it does not include: motor parameters, calibration parameter group, and cipher code group; If it is set to 19, the factory parameters will be restored, but it does not include: motor parameters and cipher groups.
