Hello,
I’m having a difficult time grasping the idea of ladder units. I’ve been working in PicPro recently, and it keeps referencing the term ladder units. When I go and look up the term, it mentions a couple other units. So the three units are,
Ladder Units
Feedback Units
Axis Units
It says that ladder units are simply the units used in the ladder… What exactly does that mean? It then goes on to say feedback units are the units the Servo uses and axis units are the units of the system… It then proceeds to talk about scaling between everything.
So besides the fact that I’m not confident with the real definitions of all of these “units”, the scaling confuses me. Would it be correct to assume that feedback units are the smallest increments of positioning a servo? But then why would you have the ability to make ladder units smaller than feedback units? Isn’t that just adding precision within your ladder that you have no control over? And I have no idea what axis units are. Could that be degrees or radians?
These terms seem to only be referenced by G&L manuals when I google them and can’t find any other PLC developer talking about them.
