my abb acs model vfd is showing A5001 error
the A5001 signal from control panel means that drive is not responding.
May be you have a fault on control panel or in the interface between control unit and panel or directly in the main board of drive.
In every case, the approach for the solution start with the correct detection of the code of drive and if you have the correct tools to test it.
Do you have one other panel to test if the first panel is ok?
Do you have another drive to test the panel?
What happened when appeared the first time the alarm?
Have you tested with switch off/on the drive?
If you give as more information, we can help you better
