solution running servo's

Hello Jon, Harrison en the rest

Thanks for your interest in my running problem.
For your interest I solved the problem.

The running of the servo's (even no DAC-cable was connected) was probably due to the fact that to much gain was given on the amp's. I measured 62mV on the amp's when the original cable was reconnected. So to enable EMC to work with the original settings I had to have the same voltage on the DAC cable when EMC-start-up. Fred had foreseen this possibility with the, offset ,second value in the OUPUT parameter. The moment you start-up Xemc you have this voltage on your DAC-Cable.
The running of the servo's when starting EMC when the cable was connected was due to the fact that the machine would seek for a homepuls.
Still don't know way he does that automatically(sometimes) but I progress.
If somebody knows what really happens behind the scene when EMC start-up, or if you know if this was publicised yet, I would really like to hear from you as it would enable me to understand more of what I'm doing.

BTW Do not forget a GROUNDING CABLE , I just ruined an encoder card!

So long,

Jan
