Can anyone help with an issue I am having when trying to start the machine. When I throw the main switch I get an "AL-19" alarm on the small Mode/date panel. I have had some success by pressing all 4 of the setting buttons as I throw the main switch and manage to get the machine running sometimes. When I fire up the Operating screen I see "Spindle Drive Fault" but cannot find any information regarding this. Any help will be most welcome.

I can't find a manual for it but have found a list of fault codes online that says Excessive U phase current detection circuit offset
