TMDSHVMTRINSPIN: Evaluating InstaSpin for absolute position control


I  need to caveat all of the following with "I've only just picked this up, so bear with my stupidity"...

Looking to find the quickest/simplest way to get to an absolute position control demonstration using the HV Eval box (TMDSHVMTRINSPIN), HV motor (HVBLDCMTR) and an SSI absolute encoder.

Q1: is there anything built into the eval software which will enable absolute position controlling?

Q2: does the eval kit support the insertion of an SSI-interfaced absolute encoder?

Q3: can anyone recommend a fast solution to getting position control operational?

Apologies for the strange tack: although I'm personally sold on using Instaspin technologies, I need to convince some non-technical people this is the way forward: simplest way to do this is to have a motor running in front of them!



  • Hi Mathew,

    First, to make things clear, I will assume you mean InstaSPIN-Motion, as you are trying to use absolute encoder in your project and trying to do position control. Please correct me if I am wrong.

    To run InstaSPIN-Motion position control, the lab13a in motorware is a good example to look at. You may start with lab12a to identify the motor parameters. Note these labs suppose you are using incremental encoder.

    For SSI encoder, we do not have official support on that right now.

    Best regards,

  • You may download the controlSUITE from TI website, and install it, you will find a example project and guide which support absolute position encoder interface. TMDSHVMTRINSPIN is difficult to support the SSI-interfaced absolute encoder, the IDDK should be OK. I have also asked our servo expert to add his comments on your question.
