Topic: Controlling a Galvo Kit(pt-20k) with arduino (Read 1 time) previous topic - next topic

So, i'm trying to make an circuit which can controll the X/Y galvo with Arduino. But because of few informations that the Manual gives, and no datasheet on internet, I'm having some difficulties. On the Manual, says that it have 4-pn connection for suplly, 3-pin +-15V output(yes I've measured that), and two "mysterious ports": one with 3-pin which says In+,in- and G; and other with 2-pin Signal In.

I've tried to put in the "3-pin In+" an +5V Analog signal (PWM), but the galvo just make a "vibrating sound", and it do the same if I put on "In-". And also tried with -5V too, resulting the same thing.

Please, if someone knows something, share...

Yeah, my mistake. I've cliked 2 times in the "Post" button   :*

I think you need genuine analog signals to drive this, not PWM.
