What would the highest safe RPM be for a 2048 quadrature spindle encoder
on the 7i76.
I have to use some pulleys to mount the encoder on my spindle and I
would like to use what I have on the shelf if possible.
My lathe can go to 2000 RPM maximum but after fitting a VFD it might go
higher. Not

Here's how I did it for my little Sherline mill...
Modify the Sherline control box to accept the wiring. This is an example
for the tool length probe line, but the same thing happened for the home
switch input:
Common on older large CNC lathes is a timing belt pulley that has a bore
sufficient to slide over the hollow spindle.. then a 1:1 ratio to
another large pulley that is mounted to an encoder.

That is very similar to the emco lathes... (they have a 100 line single
channel + index.) Works very well through the printer port.

Exactly what I will have to do.

Clever idea fitting the pulley over the nut.

I have some spare encoders already. As I said, I want to use what is on
the shelf already. To save a bit if cash seeing that I have to replace
the spindle motor that burned out after one hour of working (testing
light cuts). I had to replace it anyway with a VFD and new motor.

Greetings everybody;
In this new configuration to use a 5i25 in place of the parport, I have
now set the edge.N.out-width-ns to 5000 in hopes I could see the pulse
with a halmeter.
They are, all 3 of them addf'd to the 30 u-sec base-thread, but I have

50mS is still not very long for Halmeter.
Have you tried Halscope?

5000ns are 50ms, depending on the update

Hello to everybody.
I know this has nothing to do with LinuxCNC but here there is really smart
and kind people so I think you can help me out as usual :).
We have an old Mazak QT 20 with a mazatrol T1 controller, and a Fanuc model

I've been told before by an industrial repair shop that usually the
first parts to fail are the electrolytic caps on the old drive boards.
Their standard was to replace all of the electrolytics initially and
then retest the board. The logic being that if they were not bad, they

hi there
is there any alarm lamps lit on the fanuc boards for the spindle drive?
does the motor try to turn/move
if it does some odd pulsing/stutter moving most of the time it relateas
to the PG in side the motor for the speed feedback.
abit more info might help alot more in this error state.

Hello Robert.
There are four leds numbered 1 2 4 8 (I got it wrong before). The number 4
and 8 are glowing at the time the alarm is tripped.
I doubt that you can effectively test electrolytic power caps without
placing them under a similar voltage situation.
Be careful as the DC bus voltage in a drive like that can easily be
lethal. Make sure your test equipment can handle the voltage.

Leonardo, I recently had a problem very similar to this with my Kira
machining center. The light combination indicated a low voltage problem
and when checked every way I knew how, it wasn't there. So I suspected
the drive and sent it away for an expensive repair and got perilously
