#Stepper Motor Driver Module

[moose-mousse]

It works!*

So I (FINALLY) put the final touches on the software for my robot PROTO! (Listen, I am a software person, not a coming-up-with-names person)

Basically, it is a ESP32 running him. He takes HTTP messages. Either GET odometry, or PUT twist. Both just being a string containing comma separated numbers

Odometry is the robots best guess based on internal sensors where it is (Since PROTO uses stepper motors, which rotates in tiny tiny steps... it is basically counting the steps each motor takes)

Twist is speed, both in x,y and z directions, and speed in angular directions (pitch, roll and yaw). This is used to tell the robot how to move

Now, since PROTO is a robot on two wheels, with a third free-running ball ahead of him, he cannot slide to the side, or go straight up in the air. You can TRY telling him to do that, but he will not understand what you mean. Same with angular movement. PROTO can turn left or right, but he have no clue what you mean if you tell him to bend forward, or roll over.

The software is layered (Which I use a BDD diagram to plan. I love diagrams!)

Basically PROTO gets a twist command and hands that over to the Differential_Movement_Model layer.

The Differential_Movement_Model layer translate that to linear momentum (how much to move forward and backwards) and angular momentum (how much to turn left or right). combines them, and orders each wheel to move so and so fast via the Stepper_Motors layer.

The Stepper_Motors turns the wanted speed, into how many steps each stepper motor will have to do per second, and makes sure that the wanted speed can be achieved by the motors. It also makes sure that the wheels turn the right way, no matter how they are mounted (In PROTO's case, if both wheels turn clockwise, the right wheel is going forward, and the left backwards.). It then sends this steps per second request down to the Peripheral_Hub layer.

The Peripheral_Hub layer is just a hub... as the name implies, it calls the needed driver functions to turn off/on pins, have timers count steps and run a PWM (Pulse-width modulation. It sends pulses of a particular size at a specific frequency) signal to the driver boards.

Layering it, also means it is a lot easer to test a layer. Basically, if I want to test, I change 1 variable in the build files and a mock layer is build underneath whatever layer I want to test.

So if I want to test the Stepper_Motors layer, I have a mock Peripheral_Hub layer, so if there are errors in the Peripheral_Hub layer, these do not show up when I am testing the stepper motor layer.

The HTTP server part is basically a standard ESP32 example server, where I have removed all the HTTP call handlers, and made my own 2 instead. Done done.

So since the software works... of course I am immediately having hardware problems. The stepper motors are not NEARLY as strong as they need to be... have to figure something out... maybe they are not getting the power they need... or I need smaller wheels... or I will have to buy a gearbox to make them slower but stronger... in which case I should proberbly also fix the freaking cannot-change-the-micro-stepping problem with the driver boards, since otherwise PROTO will go from a max speed of 0.3 meters per second, to most likely 0.06 meters per second which... is... a bit slow...

But software works! And PROTO can happily move his wheels and pretend he is driving somewhere when on his maintenance stand (Yes. it LOOKS like 2 empty cardboard boxes, but I am telling you it is a maintenance stand... since it sounds a lot better :p )

I have gone over everything really quickly in this post... if someone wants me to cover a part of PROTO, just comment which one, and I will most likely do it (I have lost all sense of which parts of this project is interesting to people who are not doing the project)

For effective operation on such systems, though, specific best practices must be followed. Through this guide, we have learned how you can optimize your performance through best practice PLC Stepper Motor Control systems that will allow your automation processes to reach their maximum capabilities.

Understanding PLC Stepper Motor Control

Understanding the best practices also involves understanding the PLC and stepper motor interaction. A stepper motor is a brushless DC motor divided into discrete steps, with precise positional control. A PLC communicates with the motor through driver modules by sending electrical pulses that determine the movement of the motor.

Effective control of these systems can lead to increased accuracy of operation, less consumption of energy, and longer lifespan. This is where optimum performance through best practices for PLC stepper motor control systems comes in handy.

Why Use Stepper Motors with PLCs?

Stepper motors are preferred in automation for several reasons:

Precision: Ideal for applications requiring accurate positioning, such as CNC machines or 3D printers.

Inspecting Wiring: Look for signs of wear or damage in cables.

Maintenance is done consistently in a manner that your system operates on its highest performance, further optimizing performance by best practices for PLC stepper motor control systems.

Enhancing System Efficiency

1. Energy Optimization

Stepper motors consume more power compared to the normal DC motors, and this is especially in holding torque. In order to optimize energy use:

Use a microstepping driver to cut down current at lower speeds.

Implement sleep modes in your PLC program when the motor is idle.

Opt for low power stepper motors when high torque is unnecessary.

Energy-efficient performance means a foundation of optimizing performance by best practices for PLC stepper motor control systems.

2. Integration with Advanced Sensors

Modern PLC systems can integrate with advanced sensors for real-time monitoring and control. Examples include:

Proximity Sensors: Detect the position of objects to trigger motor actions.

Temperature Sensors: Monitor motor temperature to prevent overheating.

Vibration sensors: Identify mechanical issues early.

Sensor integration helps the achievement of automation, improving the PLC stepper motor system by best practices in order to achieve desired performance.

Challenges in PLC Stepper Motor Control

Although stepper motors are reliable, some challenges may appear, such as:

Resonance Issues: Can cause significant vibrations and reduce motor lifespan.

Overheating: Often due to improper settings on current.

Step Loss: It occurs when the motor cannot keep with command pulses.

All these challenges should be addressed by following up the best practices in optimizing performance by the PLC stepper motor control systems.

Conclusion

In the automation world, stepper motors and PLCs will take center stage in providing precision and efficiency. However, the performance in stepper motor control with PLC depends on proper selection, programming, maintenance, and integration with cutting-edge tools. Thus, by perfecting performance with best practices in PLC Stepper Motor Control, you are assured of smoother operations, cost cutting, and longer-lived equipment.

I have also been working on the 2:1 reduction gearbox that I want to add to each of the motor/wheel assemblies. I have printed the gears on the Prusa FDM for now until I get the design worked out, but I intend to resin print the gears for the final iteration. The picture here also shows a bunch of DRV8825 micro-stepping driver modules that I intend to use to drive the Nema 17 stepper motors. One module per motor obviously. Although I have bought ten of them so that I can ultimately make a second identical robot and have a couple of spare modules too. No way am I going to repeat the annoyance of no spare parts when something fails in the future.

Solutions to faults during operation of stepper motor drivers

1.Basic understanding of stepper motor drivers A stepper motor driver is an actuator that converts electrical pulses into angular displacements. It drives the stepper motor to rotate a fixed angle in the set direction by receiving control signals. The stepper motor driver is an important component of the stepper motor system, responsible for converting the control signal into the current and voltage required by the stepper motor to drive the motor for precise angular or linear displacement. The working principle of the stepper motor driver is to convert the input pulse signal into a drive current signal to control the angular displacement of the stepper motor. The speed of the motor is proportional to the pulse frequency, so the speed can be accurately adjusted by controlling the pulse frequency, and the positioning can be accurately achieved by controlling the number of pulses. The stepper motor driver has high positioning accuracy and stability, and can subdivide each step into smaller steps through the subdivision function, thereby improving positioning accuracy and stability.

2.The main structure of the stepper motor driver 1.Ring distributor. Generate the switching waveform signal processing of the motor in different states according to the requirements of the input signal. Perform PWM modulation on the switching signal waveform generated by the ring distributor and filter and shape the related waveform. 2.Protection circuit. When the winding current is too large, a shutdown signal is generated to shut down the main circuit to protect the motor driver and motor winding. 3.Sensor. Real-time monitoring of the position and angle of the motor, and the signal generation device is transmitted back.

3.Solutions to faults during operation of stepper motor drivers 1.The motor does not rotate or rotates slowly: The stepper motor driver needs to receive the correct pulse signal to control the motor rotation. If the motor does not rotate or rotates slowly, first check whether the pulse signal source is working properly, ensure that the driver input terminal is connected correctly, and check whether the motor wiring is correct to eliminate the motor itself. 2.Overheating: The stepper motor driver may overheat when working for a long time or overloaded. Improve the heat dissipation conditions, add fans or heat sinks, ensure that the working environment temperature is suitable, and avoid long-term overload operation. 3.Excessive noise: Abnormal noise during motor operation may be caused by bearing damage or loose internal parts. Check whether the motor bearing is damaged, re-tighten the loose internal parts, and adjust the driver current setting. ‌4.Overcurrent protection‌: The driver has an overcurrent protection function. If the output current exceeds the rated value, the driver will cut off the power supply to protect the motor and itself. Check the power supply and motor load, and readjust the current setting‌. ‌5.Communication error‌: If the driver and controller are controlled by communication, communication errors may indicate that the driver cannot work properly. Check the communication line and settings to ensure stable communication‌.

4.Precautions for using stepper motor drivers

1.Power management‌: The quality of the power supply directly affects the performance and power consumption of the driver. The ripple size of the power supply affects the accuracy of the subdivision, and the suppression ability of the power supply common mode interference affects the anti-interference of the system. Therefore, for applications with higher requirements, users must pay attention to improving the quality of the power supply‌. In addition, the installation of the driver should ensure good ventilation, and regularly check whether the cooling fan is running normally‌. ‌2.Signal line processing‌: When wiring the system, the principle of separating the power line (motor phase line, power line) from the weak current signal line should be followed to avoid interference with the control signal. When it is impossible to wire separately or there is a strong interference source, it is best to use shielded cable to transmit the control signal‌. Using a higher level control signal is also meaningful for resisting interference. ‌3.Initial operation check: Do not connect all the lines at the beginning. You can connect the most basic system first, and then complete all the connections after confirming that it is running well. Carefully observe the sound and temperature rise of the motor. If any abnormality is found, it should be stopped and adjusted immediately. ‌4.Environmental adaptation: Due to the drastic changes in the storage and transportation environment temperature, condensation or frost is easy to occur. At this time, the driver should be placed for more than 12 hours. After the driver temperature is consistent with the ambient temperature, it can be powered on. If stored in an unsuitable environment for a long time, the quality of the product should be retested before operation.
