Resolver to Quadrature Converter? Is this what u were talking about earlier?

Thats good that the Kanalog can take differential signalling, in my opinion all should be like that, some are starting to see the benefits but its slow to catch on.

Are there any clues to the output of that board? Any labels of what the output signals are, they may well be ttl outputs.
If you have a scope it may be possible for you to test it out.
What model of Bandit control do you have? It might help finding out information, although that may be hard to come by on such a control.

I am unfamiliar with how to test for a signal. I was wondering how much of the bandit will I be using because up until now it's just been a paper weight. Also my spindle motor isn't turning on. I have my work cut out for me.

What you would need to do is test each output of that board as you turned the motor, if indeed there is such outputs, cant really see much from the pics. Are there any labels on the pins suggesting what they may be?

Really you wouldnt be using any of the Bandit unless this board does do the resolver to ttl conversion, if it does then it would hopefully be possible to use that instead of getting encoders. All other boards will be tossed I would think. Spindle control would be from the Kanalog to your spindle drive and likewise axis control from Kanalog to the axis drives.

IF I remember correctly the Kflop stuf can handle resolvers directly.

You may want to give TOM a call or email him to verify.

Received the boards today. I tore apart an old comp and mounted it in there.

I honestly don't know what to ask about the resolvers and KFlop.

I have looked at the web page and dont see anything that suggests they do but to make sure you could just ask them if the Kanalog will accept resolver input.

Here is my reply from Tom Re: [DynoMotion] Kanalog/KFlop resolver input?


Re: [DynoMotion] Kanalog/KFlop resolver input?

Hi Matt,
 
KFLOP+Kanalog does have a resolver input mode.  If you feed in the resolver sine/cosine outputs into two Kanalog DACS it will compute the atan and track the position.  Resolvers are not usually as linear, precise, and straightforward as optical encoders.

Does it accept resolver input ?
