ACS800 display failure
We have a ACS800 on which the display never continues past the firmware version stage after power up of the drive, see attached photo.
We have tested to use another display, does not work.
The display from the faulty drive works on other vfd.
We have checked the RJ45 connector, that connects the display to the drive.
Greatful for any suggestion on fault finding.
About the description of malfunctioning, IMHO probably you have one fault at the control board inside the drive.
To exclude this event, you should connect the drive with PC and SW (Drive Window or Drive Window Lite plus NPCU-01 adapter).
If the connection with PC as above descripted and the drive not working, you have the confirm that the problem is inside the control board, external panel communication section.
Contact your local ABB dealer for more support.
Hope this help you
