Well I finally got the 4th axis running. However when I tell it to spin 180 degrees it spins all the way around. Not sure which setting I need to change.

I got a Yaskawa servo drive parameter list from Milltronics after many messages back and forth. As well as a rotary setup sheet to change a few control parameters.

I also want to figure out where the little homing program is that tells the machine how far to go after finding the home switch . Well, mine is now a prox sensor I had to figure out how to wire up using the prox sensor triggering a relay to mimic the home switch wiring diagram. Thank God for YouTube. I can move the little home block inside the 4th axis, but that's only a rough setting. I would like to find out how to get it homed exactly where I want it.

The final drive motor to table on this Tanshing VRNC-210 is 90:1

Here's a list of parameters I changed on the servo drive and control.

I can't imagine what a pain in the ass this would have been had I used a DMM servo motor and drive as I originally planned. The time I've spent banging my head against the wall is time I could have spent working on my client's projects. The $100 cable to hook up SigmaWin to the drive was only useful for entering all the parameters as apparently nobody knows how to use it, or is willing to share their dark magic.

Hi,
using manufacturers software to program the drive is MOST useful. All decent servo manufacturers have such software including DMM.

As it turns out most modern AC servos are very similar and notwithstanding the different terminology used by different manufacturers if you can program a Yaskawa then
you'll probably be fine with DMM or Delta or.....

I personally use Delta servos, and even bought ($50USD) a cable to connect the servo to the PC and program them that way. Of course you reuse the same cable for every servo drive
you want to program....its not like you have to buy a new one every time you get a new servo. Programming a drive with the software is a breeze whereas programming by pushing buttons like
a microwave is really tedious and error prone.

Look at the tuning parameters, there will almost certainly be a way of reversing the sense of the Direction signal. Change just one parameter and you'll be good to go.

If the sigma II Motor and Drive are a correct match, then there is no main Parameters to add just may be some of the motor specs, very simple, as the Drive will automatically set the Parameters if the motor is a match, there auto Tuning will get it near to where it can be without a load, if you add a load then you will have to tune it again.

You are asking for help to tune this Yaskawa Sigma II Drives and Motor and say DMM would be a pain in the ass, when it would have been a lot easier to use the DMM Drive and Motor just 3 Parameters to mess with, if you want too, they also have auto tuning which I have never had to use, out of the box you would have been running with no Parameters to set to get something running
