Hi, i'm speaking from Angola . I really appreciate your vídeos. So I'd love to know what to do when the vfd even powered , but take long to Run the motor.
I did reveived this VLT 2800 as a used one and when I started it for the first time it displayed Err 7. I did try to reset to factory setting by holding down the (quick menue and + and change data) while switching it on, but didn't work! I just want to reset it to factory setting. Can't find out how!
you can do this by tow ways, first one, turn off inverter till the LCD got off, press main menu , status, ok at same time and turn on again the drive will be initialized the second way using menu commands, go to 14-sepcial fu8nction, then 14-2 reset functions, then 14-22 operation mode and press ok, then using up and down arrows chose 2-initialisation then press ok, restart the drive it will initialized good luck
The ramp up and ramp down, are these two parameters the acceleration values? I have a VFD danfoss fcd300, and the way it speeds up to its maximum values is too fast. How could I slow this down?
Hello thank you for your videos. Relying on your experience, I have a question about danfoss fc302 cranes liebherr. The driver works for 2 days without any problems. Sometimes the free stop passes and the load is released. The driver came to our workshop for repair. We suspected the control card. When you replace the control board, the panel freezes, but it displays an internal fault error (A38). power card does not recognize the control card. This is the mco 351 card with drivers with liebherr cranes application. How to solve this problem should be followed. THANK YOU.
I'm sorry Erdal, have not worked in cranes before, we usually use dandies drives in fans, rotary valves, pumps and screws, but you can't use a control card and power cards of different versions,
