Hi everyone.
I got the endless "booting/connection" sequence on my Lenze 9400 HighLine. EZAEBK1001 Keypad is showing "question mark" while trying to connect to VFD. (check the attachment)

Unfortunately I don't have any diagnostic modules like Lecom A/B.

The keypad itself works well, I've checked on another Lenze VFD.
Any suggestions? Thank you in advance!
