DRV8305-Q1EVM: PTP BLDC motor spin

Part Number: DRV8305-Q1EVM
Other Parts Discussed in Thread: MOTORWARE, TMS320F28027F,

Hello,

A few days ago I received the DRV8305Q1-EVM. I am trying to understand how to work with the InstaSPIN-FOC MotorWare GUI (or with the CCS) for my requirements.

I need to actuate a Point To Point move with a constant velocity. How could I actuate this motion? Which LAB should I use for such a motion?

If I need a very accurate position for the velocity change ( from 200deg/sec to -200deg/sec) , could I connect a 18 bit encoder to this board? Does the TMS320F28027F have encoder inputs?

Thanks for your help!

Eli

    1. The DRV8305-Q1EVM based on F28027F just supports InstaSPIN-FCO, can't be used for motion control as well. You may have a look at the InstaSPIN lab guide to know what lab and device/board can be used for motion control.

    Download the motorWare software as the following link and install it by default.

    The instaSPIN lab guide can be found in the below folder 

    C:\ti\motorware\motorware_1_01_00_18\docs\labs

    2. That depends on the interface of the encoder. You may check the encoder spec and F28027F datasheet.
