thanks!
7i72: oh shi.... sorry... I missed that somehow.
tried mesact with it, sadly does not put out any working stuff.
pncconf did!
machine is starting and I can jog until following error again.
in general:
if I don't want to wire encoders to the mesa, I have no feedback. so far I understand. But is that a bad thing? It would be like running with steppers open loop, isn't it?
I thought it should work, as it obviously did successfully with the old (now dead) controller before for years (so far I looked up all signals that came from the old controller was analog voltage, all feedback is in servo controllers)
if I connect back the error signal from the servo drives I should be able to estop if thinks go out of control. just like I know from another project with stepper drives. that at least was my thought to remove complexity , since I am completely new to servos.
is that a completely bad idea in your opinion?
In Office I can't test with motors because they are 400v... also the machine is a few km away and I am trying to prepare it, until I can come back to it.
I just wanted to test whether or not I get +-10v on the ports to make sure it's virtually wired correctly. Also I want to try if I can cancel movement with e-stop. is at least have to find a way to ignore feedback for now, to have room to elaborate my config. it would be kind of sad to drive there just to see I missed something essential to test-drive or tune.
i also found the 7i77 servo tune post, wich I am currently reading to get used to what I need to do in future.
any workflows / hints appreciated.
as I said, I am a beginner and just trying to figure out things, bumping into new stuff on the way
Thanks for your patience and answers
