MCT8329A: configuration of Forward-Reverse control profiles

Joe Zeng

Part Number: MCT8329A

Dear sir，

          If possible, could you support to configure the values of the relevant registers as an example for "Forward-Reverse control profiles" applicaton base on  MCT8329A-EVM board?

         Thanks a lot!

    Hi Joe,

    Thanks for your question on the Motor Drives E2E Forum. 

    I will aim to provide an answer on this by the end of the week!

    Hi Joe,

    Do you mean that you want a recommended registers values configuration for each of the input control signal profiles (linear, step, forward-reverse) in the GUI?

    Or are you wondering how to configure each of the input control signal profiles?

    In either case please review section "7.3.7.5.3 Forward-Reverse Profiles" of the datasheet to find your answer.

    Best,

    Robert

    Hi Andrew,

                We set the registers for forward-reverse application, but the results were not very successful. Could you help to set the registers as an example for forward-reverse application?

               Thanks!

    Hi Joe,

    We do not have recommended register configuration for the forward-reverse control profile. It is typically up to customers to set the x and y points for the control profiles. 

    The only mandatory condition is that the values along the x axis should be in increasing order. For example dutyoff1 <= dutyon1 <= duty clamp1 <= dutya..... etc. 

    Typically direction reversal is set at 50% but not mandatory. Customer should configure the registers specifically to their application.

    Best,

    Robert
