Preface Starting from MCSDK 6.x, position control can be generated directly, but currently only for standard encoders—others still require modifications. So how should we make these changes? We can explain this using a few examples. For interfaces like I2C or SPI, the implementation is mainly based on adapting ST-generated code, meaning only two control loops […]

Preface The customer often encounters layout issues in motor control design, many of which are related to structural know-how. ST provides essential design guidance to help avoid common pitfalls in motor control, which can lead to excessive noise in the ADC feedback circuit that interferes with actual motor control. Additionally, we provide guidelines on MOS

Preface Figuring out what constitutes good motor control and how to make adjustments has always been a challenge for many newcomers. Here, we’ll provide a detailed introduction with real-life examples and useful tools, starting from using Motor Pilot to detect motor parameters, then moving on to Open loop HW debugging, and finally transitioning to Close

Preface MCSDK has added a custom graphical mode in version 6.3.0, making it relatively convenient. However, in version 6.2.X, you need to manually modify the JSON to add custom functions, which is relatively cumbersome. Additionally, you must first ensure that the MCU pins meet the functional requirements. Here, I’ll provide instructions on how to make

Preface When using MCSDK for motor control, adding additional channels to the existing ADC poses challenges due to considerations such as sampling rates. Attempting to add ADC channels directly using STM32CubeMX may result in system failure. This information is provided to address how to add channels for sampling shunt resistors in a motor control project.

Preface The customer used MCSDK 5.4.8 to generate code for a Hall sensor, but when the motor had a load during startup, there was a magnetic excitation noise. However, there were no additions to the code, only a motor stop and restart. We used the DAC interface for easy debugging and ultimately identified algorithmic adjustments

Preface This section will address common issues encountered with MCSDK and provide explanations and adjustments. Relevant information locations will also be organized to facilitate a quicker start for everyone in motor control. MCSDK Program Main Structure After generating code using MCSDK, the main program section and mathematical equations are as shown in the following figure:

Preface When using the ST FOC motor control library with Hall signals as the position feedback, synchronous electrical angle data must be input based on the characteristics of the motor being used. This data synchronizes the electrical angle with the Hall signal at each signal change. If the angle deviation is large, it may affect

Preface In MC SDK 5.x, there are two control loops, the current loop and the speed (torque) loop. Some applications require the use of a position loop, such as motor control for UAV gimbal or subway gates. This article will explain how to add a simple position loop on top of the existing ST motor

Preface The previous post described the main program structure generated by the STM32 Motor Control Workbench. Here we will continue to explain the three core task flows and structures that depend on the main structure, which are mainly divided into three parts: safety tasks, medium frequency tasks, and high frequency tasks. The safety task mainly
