C2000ware Motor Control Sdk Work ★ Trusted
The SDK supports a wide array of control strategies, but it is most renowned for Field Oriented Control (FOC).
Cause: Wrong PWM frequency or deadband configuration.
Fix: Navigate to hal.c and verify EPWM_setDeadBand. For a 20 kHz PWM, deadband should match your IGBT/MOSFET (typically 100 ns to 500 ns). The SDK does not auto-detect this; you must set it manually.
When working with the SDK, the typical workflow involves the following stages:
Stage 1: Hardware Setup
You identify your LaunchPad (LAUNCHXL-F28379D, LAUNCHXL-F280049C, etc.) and the associated BoosterPack (power stage). The SDK includes board files that map the pins correctly (e.g., which PWM outputs drive the gates, which ADC inputs read the current shunts). c2000ware motor control sdk work
Stage 2: Software Configuration
Using TI SysConfig, a graphical configuration tool integrated into CCS (Code Composer Studio), you can generate initialization code. Instead of writing hundreds of lines of register settings, you click checkboxes to enable PWMs, set dead-band values, and configure ADC triggers. SysConfig generates the C code that integrates directly with the SDK drivers.
Stage 3: Tuning and Observability
The SDK integrates seamlessly with the MotorControl SDK GUI. This is a vital tool for debugging. It communicates with the MCU via UART (SCI) to allow real-time graphing of variables (Speed, Iq, Id) and adjusting gains (Kp, Ki) while the motor is spinning.
Stage 4: Customization
Once the reference lab is running, developers typically strip away the GUI overhead and integrate the motor control system state machine into their final application code, adding communication stacks (CAN, EtherCAT) or safety logic. The SDK supports a wide array of control
Why use C2000Ware Motor Control SDK instead of writing your own or using STM32’s MCSDK?
| Feature | C2000Ware SDK | STM32 MCSDK | Bare-Metal |
| :--- | :--- | :--- | :--- |
| Time to FOC | 2 hours (with LaunchPad) | 3 hours | 3 months |
| Estimation Algorithm | FAST, eSMO, HFI | Observer, PLL | Custom design needed |
| Math Acceleration | TMU & CLA (Hardware) | FPU only | C code |
| Safety Integrations | SIL-3 diagnostics | Basic failsafe | None |
| Ease of "Work" | High (documented labs) | Medium (steeper learning) | Low |
The SDK "works" because TI abstracted the hardware complexity. The CLA (Control Law Accelerator) can run the FOC loop in parallel to the main CPU, but the SDK handles the semaphore management automatically. For a 20 kHz PWM, deadband should match
For motors spinning above 100,000 rpm, the default FAST observer gains may become unstable. Use the SDK’s FAST_setGains function.
How it works: The observer gain is a function of electrical speed (est_speed_Hz). The SDK’s FAST_setGains recomputes the observer poles at runtime. This is done in motor_common.c’s speed ramp handler.
When an engineer asks, "How do I make the C2000Ware Motor Control SDK work on my custom board?" the answer is a systematic process. Here is the standard workflow for a successful implementation.
