Hmm, okay. That means mine's broke then.
I powered it up, pack in place, heads retracted.
The fan comes on, the "READY" lite comes on,
but it doesn't sound like it's spinning up.
No "FAULT" lite.
I pull the pack (heads still retracted), and
turn it on whilst fooling the pack inserted/door closed
switch. The spindle turns *very* slowly, and then
stops.
With the rear cover off, it looks like it does the same
thing with the pack inserted, and cover closed.
I haven't plugged this thing into a live host interface
yet; I'm just trying to see if everything's okay first.
I read somewhere that it gets it's spindle motor clock

NO! But the RED FAULT light will be ON if the RL02 is
not plugged into the RLV12 (or RLV11) and the CPU is
not powered on.

READ BELOW FIRST. Failing that, you may want to check on the solid-state
relay controlling the spindle motor. Most AC SSR's are nothing more than a
pair of triacs or SCR's in opposite/parallel with each other, and sealed in
with an optical source to activate them. If one of the internal devices
fails in an 'open' condition, I could see it creating the kind of symptom
you're describing.

Ahhhh... and if I'd read this far, I would not have suggested that the
relay might be bad. I seem to recall that the RL02's will not even spin up
if they're not connected to a host controller and powered CPU (someone
double-check me on that, please?)
I read somewhere that it gets it's spindle motor
clock
from the RLV12/11).
This much I remember. The spindle motor is a basic AC synchronous at 3600
RPM. I could be mistaken, but I've never heard of it needing spindle clock
from the host.

The spindle motor circuit on an RL is a little more
complicated than just
an SSR. From what I remember, a signal from the sector transducer is
compared to a divided-down version of the clock from the controller. The
result is used to control the speed of the spindle motor.

Thanks, Tony. Lots of good info I'd either forgotten about or neglected.
What I'm trying to remember now is why I thought the RL02 spindle drive was
a simple on/off... Must have been thinking about a different unit...

Sounds normal yet.
Try it with the RLV in a system and cabled to the drive.

Jerome Fine replies:
I thought some more about my answer. I can't
ever remember trying to power-up a disk pack
when the FAULT LIGHT WAS ON since
that would not seem to be very useful, so I might
be wrong when I said that the drive should spin up
even if the fault light is on.
On the other hand, maybe the fault light is burned out.
Then even if the cable is not connected or the CPU
is not powered on, and the fault light should be on
when the RL02 drive is turned on, obviously the fault
light will not be on if it is indeed burned out.
Also, if the cable is connected backward (one side
only - obviously), then the fault light still comes on -
a good test to see if the cable is connected properly.
Sorry I can't help more. The last time I used an RL02
was over a year ago - and then only to help a friend.
I have not used one for myself for about 8 years.
Sincerely yours,
Jerome Fine
