Can you contol a servo thru the cheap breakout card?

Mitsubishi drive MR-J2S-10A and it's corresponding servo in step dir mode.

Or do you need something like a Mesa board at that point

Thanks

You can drive a step/dir interfaced servo via a parallel port.

You may not reach the maximum speed or may need to lower
the steps/turn because the maximum step rate will be limited
by the host PCs base thread latency.

I saw a demo by a chap who was controlling Fanuc servo drives with a parallel port. He was using PWM and DIR into an AMC drive, and reading the 4-channel commutation with p-port IO and the bldc component.

I was looking for a harmonic reduction drive to make a rotary axis and came across one attached to this drive and servo. The size looks good, but the servo appears to be extremely small to hold it from cutting forces.

.

There are some other worm gear reduction parts also that may work. I'll have to look into,

These have a big and strong crossed-roller bearing on the output side, so make a perfect 4th axis.

The 25-B is much easier to interface with a generic servo drive than the 25-C version.

Cool, thanks

what are you planing on the 4th
it may take you down to a 100:1 4Nm in Standard stepper
or as they are realy cheep now go fora 12Nm and put a timingbeld 3:1 4bearing Spindle adapter against
this brings you up to 50Nm at very low cost

Probably indexing , not very heavy stuff. Maybe some 4 axis stuff at some point.

then get you a >30:1 precice gear planatary on Ebay
i use only wormgear backlash free from Maedler
or as not the big load simply timingbelt 3:1 as i mentiond above give it a shot

IF YOU can spend the money or are willing for a harmonic drive go for it
nothing better then this
