【Application development based on NUCLEO-F746ZG motor】5. Motor operation [Copy link]

After the hardware connection is completed and the wiring is correct, you can turn on the power.

The power supply is 24V. In order to better learn FOC motor control technology, I completed the software engineering projects based on SDK5.4.6 FULL. In fact, it is also possible to use SDK5.4.6 without any impact.

For the construction of software engineering, please refer to the post [Development of applications based on NUCLEO-F746ZG motor] 2. Based on SDK5.4.5-engineering construction .

Compared with the previous content, the following content has been added:

(1) Start timer 7, whose main purpose is to provide basic timing tasks.

1. Open the software MotorControl Workbench 5.4.6 and click the button on the motor control operation interface;

2. Motor serial port connection, the default baud rate is 115200;

3. Set the motor speed. Pay special attention to the fact that the current is high when the motor starts. The power supply must be sufficient. The rated speed of the motor I use can reach 3000RPM. Because my power supply is insufficient, I can only run it at 500RPM.

4. Check the status bar to see if there is any error. If there is an error, click "Fault Ack" to reset;

5. If there are no problems, click "Start Motor".

6. Motor operation video:

After working, the motor runs smoothly. The blue indicator light of the development board is the program running indicator light, which flashes once every 500ms.

The next issue will share the block diagram structure of the program.

The motor starts and stops smoothly

Very smooth, but there are also problems. It cannot start at low speed

It feels pretty good, and the motor host computer software provided by ST is also very comfortable to look at!
