Hi,
I wonder if there are some resource available somewhere that describe how a galvo works in detail.
The theory is clear for me: there are two lines for power where a +- voltage is feed into, depending on the polarity and voltage the galvo moves into one or the other direction.
And there are some feedback-channels that show at what position the galvo really is. And that's the interesting part - how is the current position sent back? Via encoder pulses? Via an analogue signal? Something else?
Happy if someone could shed some light on this or point me to some useful information sources.
Thanks you :-)
