As Instaspin-MOTION is not recommended for new designs, what is next

Hello,

I'm researching on what are the latest microcontrollers for sensored motion control which are successors to the Instaspin-MOTION ones? Can you provide me with information to read about this topic?

    All of the C2000 devices on this portfolio overview chart (we call them Gen 3) are capable and being used for servo drives. Both centralized and decentralized architectures.

    Servo examples for Gen 3 devices are included in C2000Ware-MotorControl-SDK

    Depending on which device series fits your needs you would find relevant examples in

    C:\ti\c2000\C2000Ware_MotorControl_SDK_4_00_00_00\solutions\boostxl_3phganinv

    All of the servo examples include outer position control, velocity, torque and some form of sensor feedback (incremental, absolute, resolver). 

    What is not include that was in InstaSPIN-MOTION is the outer planning / motion engine or simplified tuning.

    Thanks for clarifying this to me. And is it still possible to do simplified tuning/motor identification using the next generation motor control SDK as it is in Instaspin-MOTION?

    Motor Identification is included in InstaSPIN-FOC sensorless solutions (that is why you used it in InstaSPIN-MOTION)

    This includes starting point "stable" tuning for the current loops and shows you how to do step response tuning to further tune the current and velocity response you require.

    The sensored solutions do not include motor ID.

    When using the Fast Current Loop solution there is some current tuning capability demonstrated.

    Neither offers the InstaSPIN-MOTION inertia ID or simplified 1 variable tuning.
