Reverse an axis #5

Closed josephernest closed 1 year ago

josephernest commented 2 years ago

I noticed that one axis is reversed in my setup: when position moves from 9.000 to 9.100, the controller moves from left to right (or right to left I don't remember!) but all I know is that it is reversed :) Is there a command (like RON, FRF, SVO, etc.) in pipython to configure an axis to automatically reverse the direction?

Of course I could just replace x by 18 - x so that 8.5 will automatically be 9.5 (symmetry with center 9.000), but I wondered if it's possible directly at API level.

Hello, this depends on your stage and controller. I think you change a few parameters with SPA to achive this behavior, but we would not recomend this. RON, FRF, or SVO will not change the direction of positve motion, this is defined in the controller.
