Getting Instaspin sensorless detection chip to work

Awantha Jayasiri

Other Parts Discussed in Thread: MOTORWARE

I found that TMS320F28027F chip was names as an Instaspin enabled device, which include instaspin-FOC. I have few questions now:

1) Is that a C2000 processor?

2) Does the Instaspin_FAST IP included in the chip's rom?

3) Right now we only interested with sensorless estimation (using only the instaspin-FAST) not the FOC. What would be the easiest way to use chip?

4) Seems the chip has a temperature sensor. How can we access it?

5) Can the motor parameters be automatically determined and stored for Instaspin? i.e. is minimum manual work required for the customer?

6) Any advantages of using dual instaspin (controlling 2 motors using single ship) over the single instaspin? 

Any help is greatly appreciated!

    1) Is that a C2000 processor?
    A: Yes, it's a C2000 MCU.
    2) Does the Instaspin_FAST IP included in the chip's rom?
    A: Right.
    3) Right now we only interested with sensorless estimation (using only the instaspin-FAST) not the FOC. What would be the easiest way to use chip?
    A: Please download motorware from TI website, and can find more detail in InstaSPIN user guide and InstaSPIN lan guide.
    4) Seems the chip has a temperature sensor. How can we access it?
    A: Please refer to datasheet and technical reference guide, and there is a example project in TI controSUITE to show how to use it.
    5) Can the motor parameters be automatically determined and stored for Instaspin? i.e. is minimum manual work required for the customer?
    A: InstaSPIN can identify the motor parameters automatically, you need to write the identified parameters in user.h manually.
    6) Any advantages of using dual instaspin (controlling 2 motors using single ship) over the single instaspin?
    A: InstaSPIN is a estimator, control dual or single motor depend on controller. F28027F can only be used for single motor drive, F28054F and F28069F can be used for dual motor.
