Hi,
Yeah, I had that problem too, it sounded kool, and as my servo already had everything needed to do it....I did it. I've used it less than a dozen times over several years, while I useI confess that I may be never do rigid tapping but since I'm in the middle of my scratch project my aim is the best I can have. You know, rigid tapping sounds cool : d
the free running spindle function whenever I have this particular spindle installed. I have a high-speed low torque spindle (24000rpm, 800W) which I use mostly, and this low speed high(er)
torque spindle (3500rpm, 1.8kW) which I install for milling steel.
I am just commissioning my new build mill now....and I won't be bothered with rigid tapping for a while yet. The main (still) use of my mill is making PCBs.....its what pays, I'll fiddle about
with the other stuff at a later date.

News:
I did contact to ABB support last week and asked if a digital input can be used to reverse direction. They answered:
Hi Suat,
This is not a standard configuration that we use so you would have to use a Mint program to achieve it.
The Mint program could be quite simple. Just invert the analog input when a digital input is true;
Loop
If INX(1) Then 'In this case I use DI1
ADCGAIN(0)=-100
Else
ADCGAIN(0)=100
End If
End Loop
Auto
To use this:
- Go to Edit and Debug
- Open a new blank program
- copy and paste the above code
- Press the play button to download and run
Any questions let me know.
Best Regards
I tried and it worked like a charm. Now I'm able to reverse direction with just one onboard relay. No need for the external relay.

Glad you got it all worked out. I was going to point you to a small board that provides +/- 10VDC for your spindle drive.This what I'm going to use IF I can configure the spindle drive to orientate the spindle every time it stops because my spindle is BT30 and the machine has a 8 position carousel ATC.

I am in the middle of working on something very similar to you. How did you contact support for the Microflex drives, I looked and didn't see any phone or email addresses.
Thanks
Hi.....I as of late got some old servo packs which are equipped for speed circle control with +/ - 10v simple control signal. I was thinking how to test them and happened upon Arduino. Yet, as I looked I was unable to discover way (read instructional exercise) how to control bipolar simple sign, just unipolar 0-10v (utilized for darkening). So as the +/ - 10v sign control is really far reaching standard I was trusting somebody was attempting to tackle something almost identical before me and could guide me toward arrangement. That would be incredible.
If you just need to test then you just need a 10v supply and a pot this will let you test the drive in one direction if you have a power supply that has a +/- supply then you can just switch for the direction, it's quite easy to do. the snip will show you how, you can make it complicated or simple.
What are the servo drives you have.
