I am looking for the RA80 Service Manual: EK-ORA80-SV. It's not
on bitsavers, manx, and the usual places. I was given an RA80 that had
worked for its previous owner, but now it has trouble spinning up. It
gets up to about 25% speed, then the spindle motor cuts out and the
controller gives either error 1 or 4 on the internal leds, and flashes
the spinup error on the front panel lights. I scoped the speed sensor,
and it is OK. Same behavior when trying to run the 1E internal
diagnostic (manual spindle motor control). The manitenance guide and
user manual do not provide enough detail.
I really need the service manual to understand all the
interlocks that could cause the spindle motor to drop out during
spinup. I have a KDA50 and would like to get this drive running.
If someone has this manual I would appreciate your help in
getting a copy.
