1. Servo Motor Operating Principles & Internal Architecture A servo motor isn't a single type of motor — it's a motor that's been paired with a feedback device and an intelligent drive to create a closed-loop motion control system. That said, the overwhelming majority of industrial servo motors today are AC permanent magnet synchronous motors (PMSM). Understanding their internal architecture explains why they behave the way they do. The stator...

Mitsubishi MR-J4-500B AC Servo Driver: A Practical Guide for Engineers and Buyers If you've been looking for a servo drive that handles heavy-duty CNC duty cycles without fuss, the Mitsubishi MR-J4-500B is probably already on your shortlist. It's one of the more requested models we ship — and for good reason. In this guide, we'll break down exactly what makes it stand out, share a few real-world use cases from...

I. Introduction and Origin of PLC 1. Introduction to PLCPLC stands for Programmable Logic Controller. Essentially, it's an industrial control computer that has undergone initial development. It not only has a computer kernel but also incorporates many components to make it suitable for industrial control. However, it's only a general-purpose machine and cannot be used on any specific industrial equipment without secondary development. However, secondary development of programmable controllers is...

A power supply is a device that provides power to electronic equipment. Siemens PLC power supply modules are divided into PM power supply modules and PS power supply modules. What is a PM Power Supply Module? A PM power supply module, short for Module Power Supply, provides operating power to the CPU, signal modules, other expansion modules, and electrical devices (sensors, counters, etc.). PM Module Power Wiring Method: Taking the...

FANUC Spindle Motor Encoder Type: How to Read It From the Model Number (And Why It Matters) A few years ago, a machining center in a mold-making shop in Dongguan went down mid-shift with an SP0751 alarm — spindle orientation failure. The maintenance team spent two hours checking cables, swapping out the encoder unit, and rebooting the controller before someone finally looked at the motor nameplate carefully. The replacement encoder...

First, check if the power supply is working properly. If so, replace or repair the power supply. Also check the power cord connections and connectors for good contact. 2. Damaged Spindle Bearing: Another...

This article compiles some practical tips for daily PLC applications, hoping to help you use PLCs effectively. 1. Grounding Issues PLC systems have strict grounding requirements. Ideally, they should have a dedicated, independent grounding system. It's also important to ensure that other devices related to the PLC are reliably grounded. Connecting multiple circuit grounding points together can generate unexpected currents, leading to logic errors or circuit damage. Different grounding potentials...
