What is RTD thermal resistance What is the difference between two-wire and three-wire RTD In the previous article, we introduced the principle of thermocouple temperature measurement, which uses the Seebeck effect to perform temperature measurement.

How to wire RTD thermal resistance module A small partner asked about the wiring method of RTD thermal resistance. In today’s article, we take the SM1231 RTD thermal resistance module of Siemens S7-1200 series PLC as an example to introduce how to connect two-wire, three-wire and four-wire RTD sensors To the RTD module.

How does the inductive proximity switch work Proximity Switch (Proximity Switch) is a sensor that can detect the proximity of objects nearby, and it is commonly used in industrial sites. As the name suggests, as a switch (Switch), it can output two results of 0 or 1. According to different working principles, proximity switches can be divided into two types: inductive and photoelectric (mainly infrared, Infrared).

How to set motor parameters for SINAMICS V20 SINAMICS V20 is a basic inverter introduced by Siemens. There are five sizes from FSA to FSE (FS stands for Frame Size). Inverters of different sizes have different powers. The power range of the V20 series is very wide, from 0.12KW to 30KW, there are related products.

Getting started with SINAMICS V90 servo drive system (1) SINAMICS V90 is a basic servo drive introduced by Siemens, which can be combined with SIMOTICSS-1FL6 servo motor to form a servo drive system with excellent performance. In today’s article, let’s talk to you about the first lesson of getting started with the SINAMICS V90 servo drive system: understanding the servo drive.

S7-200 SMART Motion Control Stepping Motor We know that a stepper motor is composed of a stator and a rotor. The stator winding generates an induced magnetic field after energization. The induced magnetic field interacts with the rotor to turn the rotor through a certain angle.

How to use the Profinet bus node module FB33 of the CPX electrical terminal Festo's electrical terminal CPX provides many kinds of Bus Node Modules, such as CPX-FB6 for Interbus bus; CPX-FB11 for DeviceNet bus; CPX-FB13 for Profibus-DP bus; CPX-FB33 (34, 35) is used for ProfiNet bus and so on. Each of these modules has its own characteristics, which will be discussed one after another. Today, let's talk about the Profinet bus node module CPXFB33.

What is the Safe Torque Off of the inverter AC asynchronous motors play an important role in today's industrial production, and the speed regulation and control of the motors are often completed by frequency converters. In daily production, we hope that the performance of the motor is safe and reliable. This safety and reliability is manifested in two aspects:

How does radio frequency identification (RFID) work With the development of the Internet of Things, radio frequency identification (RFID) technology is increasingly being applied to industrial sites. Today in this article, we will talk to you about the working principle of RFID, and briefly introduce the related products of SICK.

How to understand the given source and control signal source of SEW inverter？ Inverter (Inverter) is the main equipment of modern AC speed regulation, and its control object is a three-phase (or single-phase) AC asynchronous motor. We know that the speed formula of a three-phase asynchronous motor is:
