Re: Kollmorgen S Series A/C Servo drives: How do I connect them for Mach 3 Step/Direc
"First of all, why are you showing a Gecko stepper drive in your circuit ? OMG,That would surely BLOW the inputs to the Servostar !
I don't actually have a gecko drive, the illustration is just a visual representation of what I'm hearing from the mach3 hobbyists from
all over the web that are trying to help. I felt as passionately as you that it was wrong. Sorry, I thought I had explained that.
OK,the person that gave you that, may have done it as a joke
You may need to add an Differential interface driver such as a AM26C31 to properly drive the A A_, B,B_ inputs.
Do I need to? (you know my drives better than me)
You can try the way IHNF said first, but pro drives like that prefer differential.
You only should need the Step and Direction signals. You may not need the enable, because your drive is probably using an other input for the enable.
But if so, would there be anything wrong with using the enable from this connector instead?
Adding too may enables without understanding exactly how Mach3 controls them can create more problems that solutions. Why do you want Mach3 to enable the servo drive ?
The step and dir outputs on the bob, go to the inputs on the AM26C31, and the differential outputs of the AM26C31 go to the A A_,B B_ inputs on the servostar.
The chip can be powered by the same 5volts that is powering the breakout board (from a USB cable) .
If so, is a quick schematic something you can help with?
Go to the Digikey link i posted and download the PDF DataSheet on the chip. You will need a perf board (from radioshack) to mount it on. use an IC socket.
You will need to configure the Servostar for 5volt Step/Dir, (not 24 volt Step/dir), probably through software."
Is this still IF I need to use this chip?
And what software? Mach3?
No, the Kolmorgan setup software
