  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

Vfd question

The price is dropping so fast, it is concievable that servo motors might include their own drivers at similar prices as today in not-too-many years. Thus servo motors could become "digital" in a sense. These controllers could even include their own oscillators and become a variable speed DC motor at some nominal voltage...
 
Donald replied back that he didn't have anything that would be suitable.
The STMBL drive originally used the IRAM256-2067A but that was discontinued. Too bad really because it had a max voltage of 600V and 20A. So generating 3 phase from a 320VDC power supply was easy. The biggest problem with the STMBL is it's Linux oriented. Which means it has good design ideas along with the crap.
Although I don't think they ever added the code to be able to use a 0-10V signal for speed control. Either step/dir or smart serial. I use step/dir for my harmonic drive which is rated at 160VDC but I'm using it with a 105VDC power supply. The harmonic drive also has an encoder but I believe the STMBL can run without one.
