Servo Wiring and Tuning detailed How To example Mesa 7i77.

Andy,

Thanks for the information on the velocity loop vs. position loop.

The drives are KollMorgen ServoStarCDs. The PCI card is an Acroloop 8020. With the reasonable price of the Mesa Cards it was way more obvious to just purchase and play, rather than write a driver. The Mesa ethernet version(s) simplifies some wiring for me as well.

Had a look last night on some servostar drives, series 6 looks very nice. Found some 606 in Germany for 400 euro a piece used but i have no clue if they are worth that. Some new ones on fleebay go for over 1000. I like the adjustability of the output voltage, encoder passthrough, tacho feedback, several control types etc. Will have to check them in more detail.

Added to the original post:
some more info and details on I and D values,
some minor editing for easier understanding.
Regards,
Tom

Is there a link to this axis screen with all the widgets somewhere?

Here you go.

Thank you!
