Search on WeChatAutomation Knowledge Base Hello everyone! Today I want to talk about a knowledge point that I learned through practical experience—how PLCs control stepper motors. I remember the first time I encountered a stepper motor, I spent a long time looking at the manual, my mind filled with terms like “pulse count” and “frequency”. … Read more
Stepper motors are commonly used for positioning control, and their rotation angle (which can also be considered as distance) is controlled by the number of pulses output from the PLC. The frequency of the pulses controls the speed of the stepper motor. For applications where control precision is not critical, this method is simple, economical, … Read more

Have you encountered issues with inaccurate positioning or stuttering when starting and stopping stepper motors? By using a master-slave timer combination with a microcontroller, these pain points can be easily resolved! Today, I will share a tested and effective … Read more
This article introduces the Proteus simulation system for a 5-wire 4-phase stepper motor driven by ULN2003. The system implements forward and reverse rotation, speed adjustment, and single-step testing functions through button control. It details the structural characteristics (5 leads/4 phase windings) and operating modes (single-phase, double-phase, eight-phase) of the 5-wire 4-phase stepper motor, as well … Read more
1. Core Concepts of Positioning Control 1. Relative Positioning (Incremental Positioning) Definition: Move a specified number of steps based on the current position Instruction: PLSY (Pulse Frequency Output) – Requires manual origin point recording – Suitable for repeated relative movements – Weaker anti-interference capability 2. Absolute Positioning (Absolute Positioning) Definition: Directly move to a preset … Read more
Introduction As an industrial control computer, PLCs have a modular structure, flexible configuration, high processing speed, and precise data processing capabilities. PLCs also have good control capabilities for stepper motors, utilizing their high-speed pulse output function or motion control function to achieve control over stepper motors. For specific devices where both the distance and speed … Read more
