LAUNCHXL-F280025C: Different hardware configurations between "Motor Control SDK" and "Servo Drive with CAN" ?

Part Number: LAUNCHXL-F280025C
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hi,

    I am going through the example projects in both the Motor Control SDK and Servo Drive with CAN on the LAUNCHXL-F280025C, and the datasheets seem to require different settings. For example,

The Motor Control SDK datasheet's section 3.2.1 says to move the S2 switches up, and section 3.2.9 says to solder on capacitors on the booster pack.

Meanwhile, in the "Servo_Drive_with_CAN_Lab_User_Guide.pdf" file located in "c:\ti\c2000\C2000Ware_MotorControl_SDK_5_03_00_00\solutions\servo_drive_with_can\doc" directory, section 4.0 Hardware Setup, there is no mention of S2 switches or any capacitors on the booster pack.

    The "Servo_Drive_with_CAN_Lab_User_Guide.pdf" is simpler, but is it outdated? Should I ignore it and follow only the SDK's datasheet? Thank you!

    Hi Shawn,

    Reason the caps on the phase voltage sensing signals are not needed in Servo_Drive_with_CAN project is that it's sensored motor control and does not use phase voltage sensing at all. Phase voltage sensing are really only needed for sensorless FAST observer.

    For S2 switch I would put in 1:1 mode in case those boosterpack IOs get used on LaunchPad site 1.

    Best,
