Hello!
When I restart my Okuma (LB15 Osb 5000 year 1998) after changing parameters for example, I get 110 alarm-a (driver unit, i believe, I got my machine language in Swedish) and when I open the door on the backside it says alarm 20 o n the top board. If I turn the machine off again and let it rest for 15 minutes it will start without any alarm. Anyone got experience and know how to fix it?
