Yaskawa DriveWorks EZ Controls Antenna’s Azimuth Axis

Here’s a postcard I got from the always helpful Adam Ring, one of our key engineered solutions pros. Adam failed to mention the temperature was around 104 degrees this day in North Texas. That’s Adam in the blue shirt in the sun, and our skateboard pro customer Dave Johnson in the white T-shirt checking things out on the meter. And yes, those are Yaskawa drives in the control box.


Here are some pictures from the customer’s Signal Test Range.  I was helping tweek the Yaskawa DriveWorks EZ control algorithm that I developed to control this new antenna’s Azimuth axis.  By the end of the day, the system was purring like a kitten.  We implemented some very creative methods to very accurately control the position of this antenna and combat the effects of backlash in the gears as well as high winds. It’s a 9.4 meter Satellite Earth Station Antenna which means it’s more than 30 feet in diameter. — Adam Ring, Innovative-IDM
