One Reason I Love Automation
One reason I love automation is that I get to play with cool stuff like this Parker Bayside rotary stage.Â It’s a jewel; besides have cool specifications, it just feels so good in my hands – and looks beautiful.Â The LED angle display is another groovy touch.
There’s a little history behind this purchase.Â Many years ago, I got to evaluate its big brother, the R200D, at work, and fell in love.Â Unfortunately, the R200D didn’t work out for that application, but when I saw this R100D at a semi-reasonable price (and much cheaper than new, which would around $4,000), I couldn’t resist.
It’s a direct-drive rotary stage, so there are no gears, just a big brushless servo motor, bearings, and a super high resolution encoder.Â One down side of the direct drive is that the rotary table can spin when there’s no power, which can be a problem.
For initial testing, I connected it to a Copley Accelnet ACP-055-18 with a Logosol LS1148 power supply, and used Copley’s automatically generated parameters.Â That doesn’t seem like the ideal combination; either I need a different drive with a higher voltage power supply, or I need to do some serious tuning.
Another reason I love having this stage is that it’s so different from all the other motors I own.Â For example, it has 12 poles (all my other motors have 4 or 6 poles), and an inductance of 50 mH.
Since many of my posts take quite a bit of work to create (especially the series posts, such as the Robot Primer), I am going to try to reduce the size of each post so I can provide more frequent content updates.
