Frequency converter debugging
Thread Content
Today I encountered a Fuling inverter model DZB-70. The fault was that it was originally controlled by the panel, but it has not been used for a long time. Now that the panel control is not usable after powering on, I saw that the parameters have a total of 102 function codes. I also restored the factory values, but it still doesn't work. Please give me some advice. Is the panel broken?
The frequency converter has many functions. As for the poster's question about whether the panel is broken, I think the main functions include voltage, frequency, current, speed, starting mode, control mode (local control and remote control). Your situation may occur in the control mode.
What the original poster means is that the panel cannot be operated. I would like to ask how you restored the factory settings. At least it means that the panel can still operate. It is estimated that the board inside is broken. If there is an inverter of the same model, take the panel over and try it. This post was last edited by XJTZWKDPJ on 2008-1-4 10:10 ]
Also, since it has not been used for a long time, would you like to check whether the wiring is normal?
I remember that Fuji has an inverter that requires hardware to short-circuit two terminals before the panel can be used. Look for the manual and read it, each one is different.
