I just recently acquired a 1983 SL-1A. It has a Yasnac LX-1 control. It was purchased on a spur of the moment sight unseen, and now I'm wondering if it was such a good idea.
Anyway, powered it up today for the first time. Quickly noted that there are 2 alarms, #280 Machine Unready, and #400 Seq Err 2. The note on the bottom of the screen says "Spindle Alarm".
On the spindle drive there is an orange/red light on next to "OC".
Any ideas what is going on here? Hoping that it doesn't need to have a drive replaced or repaired. Maybe I'm overlooking something or not following the correct sequence (SEQ ERR 2)?
Thanks in advance
