PLC products have developed microcomputer systems and are constantly improving new software development, generic cabling and functional software technology, new programmers, etc. to cope with increasingly stringent cost control structures and development processes.

With the rapid development of industry, energy and infrastructure, PLC is no longer a typical mechatronics product. Here, we will introduce the PLC classroom and control knowledge. The introduction to the programming idea of the programmable controller has not been mastered yet.

Rockwell command and Rockwell command small PLC have servo command. Hercules five way single circuit, DC 380V, 940A continuous, 24A or 48A is adopted here. It provides a kind of low voltage instruction which can be controlled by computer for programmable logic controller (plc). Low voltage commands are used, so that many low voltage hold times can be fully utilized for emergency stop and emergency power supply systems. In addition, in order to reliably implement this requirement, it uses SLIM/Express Cooling Water System (EVE) (forced water cooling). In this way, you can operate it in the initial phase (OFF).

The OFF command can induce an emergency stop and a limit speed. It uses a valve closely related to the driver. This will increase the probability of emergency stopping the airbag.

Liteele is a solenoid valve that supports a motion control to ensure that the process continues to exceed the allowable range.

Instead, you can stop when appropriate and accelerate to the preset value. The valve on the emergency stop shall not be used.

The technical level comes from the driver or servo unit. They are the key to improving speed and accuracy. On the left side of Litelee, there is a 20/33 bit absolute encoder absolute encoder position feedback for incremental encoder feedback.

The absolute encoder cuts between the main power supply (DC) and the power line. The main power supply is called commutation during operation. Accurate position feedback can also be obtained from the data information after the fault, integrated circuit and encoder information.

NAMUR interface makes servo positioning accurate and motion controller more powerful. The Pt Sate or systems command reads the interface or the built-in encoder command reads the interface directly to the relevant equipment.

Each PC can be configured with 9-axis or 10 single axis+2-axis C-axis FR axis with feedforward, or the main axis with external axis, which can be fed back by independently cascading electric ball FR axis. Only one axis is needed to achieve FR axis application.

● Digital valve controller FANUC Digital valve controller ASJN+D series can improve the functionality of P+F light source circuit and also provide light source to P+.

If the light source circuit is activated at this time, the current of P+often contains special requirements: the P+F light source circuit can be used to realize the influence of the double variable ball on the pressure control level control P+F light source circuit with the flow variable.

The P+F light source circuit is used to realize the function of the double variable sphere over time (another auxiliary pipe source), and the D+F light source circuit is used to make the solenoid valve on-off control or alarm by cutting off the power supply of the on-off control circuit.

IO has a variety of interface forms to facilitate system integration. It is used in situations where the equipment wiring height is limited. IO interface can be analog signal, digital signal or pulse signal, which is used for fast receiving, processing and sensor signal. It is used together with RJ45 interface through Ethernet interface conforming to Ethernet standard. Its input and output interfaces can rotate clockwise with the IO interface through the IO interface to facilitate the connection of the sensor and the digital input and output interface.

Requirements for home power supply: AC 220V ± 10%/100V 50Hz single-phase power - the power supply is 85-265VA.

AC220V ± 10% single-phase, 50/60Hz three-phase, local delivery measurement.

■ It integrates the latest technical achievements such as fuses, circuit breakers, contactors, thermal relays, over-current protection, control of power supply voltage waveform size, triangular wiring, body bridge wiring, etc!

■ It is easy to install and flexible in configuration. Terminals are replaced at 7~8 intersections. The safety valve is equipped with travel switch, mechanical limit and other accessories to ensure that the fault point can be found quickly;

■ With RS485 communication and analog output interface, PLC output control cycle can reach 40ms;

■ Software debut: PROFIBU I/O series touch screen PLC, frequency converter, servo and automation products.

■ Equipment R&D for equipment manufacturing industry: various small transmission devices, bridge type, series or parallel current sharing speed regulation can be widely used in various lifting machinery, bridge type, fans, water pumps, lifting winches, winches, stackers and reclaimers. It can meet the requirements of first class hoisting machinery such as cage hoist, double speed, gantry crane, gantry crane, hydraulic actuator, rocker crane, etc.

◆ Introduction At present, most of the eddy current braking eddy current speed regulating motors commonly used in China are constant torque loads. The rotation direction of the motor can be changed by changing the deceleration time, and the speed can be changed by using a frequency converter to change the motor speed. The frequency converter can change the speed by changing the frequency of the motor power supply. There is no power frequency interval between the two. The frequency conversion speed regulating system is convenient for switching, without self-learning, to set up a frequency conversion speed regulating system.
