hey stuart nice to hear from you this machine might be like some of the big ones you did
yes good question its a yaskawa inverter motor internal positioner yes i could control it. but they are worth lots of money on ebay like 3k. and i would prefer to handle it all inside linuxcnc than have a magic black box i don't understand. then i can interlink classic ladder and estops and everything etc On Fri, Jul 26, 2024 at 11:25 PM Stuart Stevenson <stus...@gmail.com> wrote: > There is not currently a carousel motor controller on the machine? > > > > On Fri, Jul 26, 2024 at 6:07 AM andrew beck <andrewbeck0...@gmail.com> > wrote: > > > hey guys just have a question about the carousel component > > > > I have a 80 tool carousel on my mazak horizontal 5axis > > > > and i need to control it. > > > > i know the carousel component can be used with a stepper motor and it > just > > needs one home switch and then calculates step and direction signals for > > any movement from there > > > > I have a couple of options here to make this work > > i could pull the current motor out which is a yaskawa inverter rated > motor > > with a 5v differential encoder on the end(ready to plug into a mesa > card). > > And then just replace it with a servo motor and use step and direction to > > control it and away we go. the downside of this is there is a spline on > > the original motor i don't really want to have to touch.. and the cost > of > > a servo and driver approx 350usd > > > > the 2nd option is a expensive vfd that has 0 +-10v i am hoping that i can > > control that as a servo and the carousel component tells it what to > rotate > > to for each tool. cost 300usd > > > > the 3rd option and the one i am hoping i can use is i buy a cheap vfd > that > > has a encoder card for closed loop control (approx80usd) and just plug > it > > into motor and wire encoder in to vfd and then back to mesa card. the > > problem is the cheap vfds only have 0-10v not +-10v > > > > so i would have to have a direction pin plus 0-10v.
