Hello,

i need a help to continue a instaspin motorware labs.

I have a PM motor with a resolver. I don't know how to connecte a resolver with QEP connector in Instaspin.

    Hanane,

    Starting with Lab12 of the instaspin_motion labs we show examples of using an encoder for angle feedback in the Velocity or Position control solutions.  The software only requires an angle though, so if you get this from a resolver that is fine.  What you will have to do is transmit it into the controller at the correct time over a diferent peripheral.  Some resolvers have a SPI output, others send out emulated encoder.

    Thank you for your help,


    I read Lab 12, My Motor is Baldor BSM 63A-250, The resolver is shown in the figure. Can I connect it?

    the kits don't accept a Resolver hardware connector.

    You need to decode the resolver signal to an angle first.  We actually will introduce a kit to do this in April....but I'm sure you have other methods.

    You can get the decoded information to the Piccolo processor through SPI or an QEP (if your resolver ouput is emulated encoder).  Then use that angle in the projects.
