SH31002S0001226A motor is a device that converts electrical energy into mechanical energy. SH31002S0001226 It utilizes an energized coil (i.e. stator winding) to generate a rotating
magnetic field and act on the rotor (such as a squirrel cage closed aluminum frame) to form a magneto electric rotational torque. Electric motors are divided into DC
motors and AC motors according to the different power sources used. Most of the motors in the power system are AC motors, SH31002S0001226 which can be synchronous motors or
asynchronous motors (the stator magnetic field speed of the motor does not maintain synchronous speed with the rotor rotation speed). An electric motor is mainly
composed of a stator and a rotor, SH31002S0001226 and the direction of the force acting on the energized wire in the magnetic field is related to the direction of the current and the direction
of the magnetic induction line (magnetic field direction). SH31002S0001226 The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

With the support of AR technology, customers can use this App to project the model plan into the actual production environment in its original size, and then rotate the model from different angles to achieve the best deployment effect.
In addition to simulating the actual delivery effect of the robot, the timeline function of this observer app also allows users to check the cycle time and quickly reach a certain time point in the simulation animation, allowing users to promptly discover ways to enhance performance or identify potential problems.
The AR viewer is an ideal operating tool for companies that are new to robotic automation, or that have previously lacked the time and resources to start robot installations.
Antti Matinlauri, head of product management for robotics at ABB, said: “We know from conversations with small and medium-sized enterprises that many currently want to implement some form of robotic automation, but they are not sure where to start. RobotStudio is what we offer them The most intuitive digital tool is designed to help them simplify the installation and use of robots. The AR viewer application launched this time is designed to allow customers to better master the use of RobotStudio and help them understand how to introduce robots before investing. production, and how automation will increase productivity and flexibility in existing processes.”

Fieldbus communication technology between PLC and ABB frequency converter
Profibus is one of the most successful fieldbuses in current industrial control systems and has been widely used. It is an open fieldbus that does not depend on the manufacturer. Various automation equipment can exchange information through the same interface protocol. Profibus-DP (Distributed I/O System) is an optimized module with a high data transmission rate and is suitable for communication between the system and external devices, especially remote I/O systems. suitable. It allows high-speed periodic small-batch data communication and is suitable for time-critical automated control systems. The Profibus-DP fieldbus system enables many field devices (such as PLCs, intelligent transmitters, and frequency converters) to conduct two-way multi-information digital communication on the same bus. Therefore, control and measurement systems produced by different manufacturers can be easily connected to each other to form a communication network. . Jinan Iron and Steel Baode Color Plate Co., Ltd. is a large-scale color plate production base with an annual output of 200,000 tons invested and built by Jinan Iron and Steel Group Corporation in 2003. The curing furnace, thermal oil furnace, and gas system in the gas hydrogen production in its production line must pass the gas. The gas pressurizer must perform secondary pressurization to meet the production process requirements. The gas pressurizer control system adopts
Using Profibus-DP process field bus communication technology solution, the automation control unit and frequency converter adopt products from different manufacturers, respectively using Siemens’ S7-300 PLC and ABB’s ACS600 frequency converter.
2 System configuration and communication protocol
(1) System configuration
This system uses related products of Siemens and ABB to realize the communication and control principle of the all-digital AC speed control system in the Profibus-DP network. The attached picture shows the network configuration diagram of the Profibus-DP network of the system, in which the PLC is SIMATIC S7-315-2DP of Siemens, the frequency converter is the ACS600 series, and NPBA-12 is the communication adapter matched with the frequency converter. The programming software is STEP7 V5.2 software, which is used for S7-300 PLC programming and Profibus-DP network configuration and communication configuration. The upper computer screen operation uses WinCC5.1 for screen programming and operation, and the communication with the PLC uses Ethernet communication.
(2) Communication protocol
In this system, S7-300 PLC serves as the master station and when the frequency converter serves as the slave station, the master station transmits operating instructions to the frequency converter and at the same time accepts the operating status and fault alarm status signals fed back by the frequency converter. The frequency converter is connected to the NPBA-12 communication adapter module, connected to the Profibus-DP network as a slave station, and accepts control from the master station SIMATIC S7-315-2DP. The NPBA-12 communication adapter module stores the process data received from the Profibus-DP network into the bidirectional RAM. Each word is addressed. The bidirectional RAM on the frequency converter side can be sorted by the addressed parameters and sent to the frequency converter. Write control words, setting values or read actual values, diagnostic information and other parameters.
From a software perspective, the core content of the inverter fieldbus control system is the fieldbus communication protocol. The data telegram structure of the Profibus-DP communication protocol is divided into protocol header, network data and protocol layer. The network data, namely PPO, includes parameter values PKW and process data PZD. Parameter values PKW are some function codes to be defined when the frequency converter is running; process data PZD are some data values to be input/output during the operation of the frequency converter, such as frequency given value, speed feedback value, current feedback value, etc. Profibus-DP has two types of network PPO: one is PZD without PKW and has 2 or 6 words; the other is PZD with PKW and 2, 6 or 10 words. The purpose of classifying and defining network data in this way is to complete different tasks, that is, the transmission of PKW and the transmission of PZD do not affect each other and work independently, so that the frequency converter can operate according to the instructions of the upper-level automation system.
