【Introduction】 Recently, I have been writing programming learning materials for Huichuan PLC, verifying the data acquisition function of Huichuan EASY521 PLC for analog voltage. We added an expansion card on top of the PLC, supporting two channels of analog voltage acquisition. After studying the user manual, I wrote the following program. The PLC data acquisition … Read more
01 Introduction This 270-degree servo is controlled by PWM signals to adjust the rotation angle (0 to 270 degrees), capable ofinstantaneously completing angle changes, with good explosive force and strong stall torque. This article will first discuss analog and digital signals, then introduce what PWM is, and finally demonstrate how to wire and program the … Read more
Pulse servo and bus servo are two mainstream servo drive methods in the field of motion control. They have significant differences in communication methods, performance characteristics, and applicable scenarios. Their respective advantages and disadvantages are as follows: 1. Pulse Servo (Pulse + Direction Control) Working Principle The servo motor is controlled by sending pulse signals … Read more
In our line of work, we often encounter situations where the equipment is compact, and adding a PLC is unnecessary, yet we still want to control servos. In fact, you can achieve this directly using a Wecon touch screen with Modbus communication! Today, using Huaxin servos as an example, I will walk you through the … Read more
