Hi,
Lets talk about servo motors, and drives.
How does one know what servo drive to go with. My understanding is bottome end scale might be Geckodrives like the G320 and G340.
Then you might go with Galil.
Then maybe higher up again with manufacturer specific drivers etc.
.......
So what I really want to know is what are the limitations of say the geckodrive G320 to say a Galil etc. I beleive that geckodrive is step/direction only and is to be used with mach series pulse engines.
Galil from my limited research seems to have to be used with Camsoft, and are of the +-10volt type.
Geckos don' have closed loop where as Galil do.
With all the different manufacturers around, how can one tell who has the better servo drives to use. for example. gecko g320 will sure enough drive servos quite fine if the machine is not overloaded and will probably position the machine accuratly all day. But so will a Galil setup, if it is used carefully and not pushing the machine hard.
So why would one need to go "higher up the ladder" so to speak tand use a Galil servo driver over a gecko servo driver if you are going to run the machine at non destructive positioning speeds.
Surely a geckodrive would be fine wouldn't it?
Then how can you tell the features and the real life benifits and differences between gecko drives, teknic drives, rutex drives and larken servo drives etc. These all seem to be the most commonly talked about drives on cnczone that I have heard of. Is this because they are lower "grade" drives that are not used on bigger industrial machines, and that they are just the most common as this is what people are using for DIY and smaller conversions and setups etc?
I'm just trying to figure out how to select a good reliable servo drive system that would be good enought to offer as an OEM solution for some machines I one day hope to make. As I would be building machines to sell to customers, I would want to make sure that the servo drives were of highest reliabilty.
Having said that, the market that I would be targeting for these smaller machines does not want to pay tens of thousands of dollars just for a servo drive etc.
So where do you draw the line?
Cheers,
Peter
