Help needed to get my 7i76E + 7i85S + 7i73 on my mill going.

It could well be due to the minlim and maxlim parameters

Where are these parameters?

spinout minlim 0
spinout maxlim 100
spinout scale 2000

Thank you very much Andy one very happy camper here now.

Your help is very much appreciated.

I have now made course adjustment of scale to 1200 so true rpm is very close.

Giving M3 S50 gives 46rpm.
Question, spindle encoder is showing approx 3000/3200 for velocity, where do I scale this?

Will put encoder aside a while as I just realized that Z puls is not working.

Back to the spindle as there are problems still or should I say need of improvements.

I have a 2-speed 3-phase motor with 1400/2850 rpm = Output 10 controls this.


As a first step I need to have monitoring of true rpm and make a switch to high rpm at say 800rpm.
How can this be done?

When I get the milling machine going I will make further improvement on controlling gearbox as I can not get good enough torque just by letting VFD go to lower revs so the gearbox is very well needed working with large milling cutters.

Looks like this





So I need to make a *reader* for the gearshift A-B-C-D-E as well as the Hi/Lo lever on the side.
All to be set manually but halting spindle for gear change to appropriate rpm.

setp hm2_7i76e.0.7i76.0.0.spinout-scalemax 1200
setp hm2_7i76e.0.7i76.0.0.spinout-maxlim 2500

Above is obviously not correct as I can not get more than 1200rpm

Encoder is a must to monitor velocity but how to implement this so the speed shift can be accomplished?

This setup was working in my previous life with other system.

Any help to get me in the right direction is most welcome.

Cheers
Bengt
