LAUNCHXL-F28P55X: CCS Project for Sensor-less FOC

Part Number: LAUNCHXL-F28P55X
Other Parts Discussed in Thread: BOOSTXL-3PHGANINV, LVSERVOMTR, C2000WARE, C2000WARE-MOTORCONTROL-SDK

Tool/software:

Hi,

I possess the following items:
1. Controller Board: [LAUNCHXL-F28P55X (TMS320F28P55x LaunchPad developm.)]
2. Inverter Board: [BOOSTXL-3PHGANINV (48-V/10-A three-phase GaN inverter)].
3. Supported Motor: Low Voltage Servo Motor - Low voltage servo (encoder) motor and wiring harness [LVSERVOMTR, P/N: M-2310P-LN-04K, Teknic M-2310P-LN-04K]

Also, I have installed Code Composer Studio (CCS Version: 12.8.0.00012) IDE for development and C2000Ware Software Development Kit (SDK Version: C2000Ware Motor Control SDK_5_02_00_00).

I was able to find only one example for the board f28p55x at the location given below which is for sensored foc:

C:\ti\c2000\C2000Ware_MotorControl_SDK_5_02_00_00\solutions\boostxl_3phganinv\f28p55x\cc

I'm considering implementing sensor less FOC to control the motor. Can you assist me by supplying the necessary information and tools for this as listed below:

1) Configuration: Pin configuration.

2) Project Generation: Can you suggest a tool for creating code for sensor less field-oriented control, considering that the example is for a sensored system?

3) Debug Tool: Is there a tool available for adjusting motor speed, altering parameters, and real-time monitoring? If not, does this tool have support for modifying parameters through any configuration file?

Thanks, and regards,

Prasanth

You may refer to the lab for the C2000 devices in motor control SDK. The universal motor control lab is available in the current MCSDK, which can support a set of hardware kits and control algorithms for BLDC/PMSM drive. The kits include LAUNCHXL-F280025C, LAUNCHXL-F280039C, LAUNCHXL-F2800137 with DRV8316REVM inverter board for low voltage motor. The control algorithms include sensorless InstaSPIN-FOC with FAST, Sensorless-FOC with eSMO, Sensored-FOC with incremental encoder, Sensored-FOC with hall sensor. You can refer to the device peripherals (ePWM, ADC, eQEP, or eCAP) configuration for porting the lab to the other C2000 devices including F2855x.

I am keeping Mr.Tashi George, one of my teammates, informed. He also utilizes the same hardware.

Ok, You can refer to the example as mentioned above. Just need to change the hal.h, hal.c and user_mtr1.h for your own board and motor.

Hi Yanming,

The project you have suggested finds usefull and got an idea on how to use the code to run for BOOSTXL-3PHGANINV.While going through the code I found out some of the areas I need to change the code like GPIO, PWM and ADC configrations. Bit I didnt find how the project can be build for LAUNCHXL-F28P55X.

Yes. Please follow the guide to port this project to LAUNCHXL-F28P55X.
