1, don't set the analog input quantity from the terminal, find a connection quantity, set it as a fixed value, and then set this connection quantity as the input word of the frequency converter. Set it to 3 at p 1000, fix the frequency setting value, and then set the frequency setting value additionally. Please refer to the "Parameter Table" for the setting method of the determined value, which depends on the settings of p0700 to p0708.

2. During the operation of the frequency converter, when any parameters are displayed, press and hold this key for 2 seconds. The following values will be displayed:? DC loop voltage (expressed in D unit: V). ? Output current (a),? Output frequency (Hz),? Output voltage (expressed in ohm unit: V). ?

Press this key several times continuously, and the above parameters will be displayed in turn. The green button is the start button and the red button is the stop button. When a fault or alarm occurs, press this key to reset the fault or alarm information displayed on the operation panel.

Extended data:

1. Dust the inverter regularly, focusing on rectifier cabinet, inverter cabinet and control cabinet. If necessary, remove the rectifier module, inverter module and circuit board in the control cabinet for dust removal. Whether the lower air inlet and upper air outlet of the inverter are blocked by dust or have too much dust. Because the inverter itself needs a lot of ventilation and heat dissipation, the surface dust is very serious after running for a certain period of time, so it must be cleaned and dusted regularly.

2. Open the front door of the inverter, disassemble the back door, and carefully check whether there is any deformation, corrosion and oxidation on the AC and DC buses, whether there is any looseness on the screws at the bus joint, whether there is any looseness on the solid screws at the fixed points, and whether there is any aging, cracking or deformation on the insulating sheet or insulation column for fixing. If there is, it should be replaced and re-fastened in time. The deformed busbar must be corrected and reinstalled.

3. After the circuit board and bus bar are dusted, necessary anti-corrosion treatment shall be carried out and insulating paint shall be painted. Busbars of partial discharge and arc discharge shall be deburred before treatment. For the insulation board that has been decomposed, the damaged part must be removed, and the insulation board with corresponding insulation grade should be isolated near the damaged part, and it can only be put into use after being fastened and tested for insulation.
