Industrial automation is one of the important prerequisites for Germany's launch of Industry 4.0, mainly in the areas of machine building and electrical engineering. The "embedded systems" that are widely used in German and international manufacturing industries are the complete application of mechanical or electrical components embedded in controlled devices. It is a special application-specific computer system. Data show that this "embedded system" achieves an annual market benefit of 20 billion euros, and this figure will rise to 40 billion euros by 2020. The speed of industrial automation has surprised everyone. Some new technologies, such as more advanced drives, fieldbus-based pneumatic devices and piezo-actuated valves, are driving the rapid development of the industry. What about the development trend of industrial automation? What are the major components that have changed the fastest?
The development trend of the driver
On the drive side we can see a clear trend: The tasks performed by the drive are more complex than in the past. But in some ways, the system itself has become easier to use. Many drive supply companies generally provide low voltage (up to about 700 volts) AC and DC variable speed drives for speed control, typically used for some types of continuous processes.
Software Control Increases and Becomes Easier
Some variable speed drives provide higher levels of control for pumps, fans, and general applications, but the equipment itself is easier to configure than in the past. The new wizard function gradually guides the user through the process automation configuration and settings. The wizard allows users to perform "clones" using interface devices or memory cards and quickly transfer the same settings and configurations to another drive.
In addition, the position control servo driver's functions such as automatic tuning and motor identification have also been further developed. When the user connects the motor to the drive, it triggers a small program to copy 90% of the application parameters that apply to the drive to the new system.
Expansion bus connection
At present, many drives are connected to various mainstream industrial fieldbus networks, but AC drives are increasingly turning to Ethernet platforms. Ethernet platforms often use a variety of different industrial field buses, including Ethernet, EtherCAT, Sercos, Powerlink, and Profinet. High-end variable speed drives can also integrate proprietary protocols such as BACnet for building automation and LonWorks for equipment networks.
More economical solution
Not only that, but more and more energy-saving technologies are also more cost-effective. For example, an AC drive such as the AC30 can be equipped with an Active Front End (AFE) power supply. The AFE power supply allows the configuration of a common bus system to take power that would otherwise be wasted (for example, when a machine on the machine is pulled up to its set speed or decelerated) with an appropriate sinusoidal current and unity power factor. Return to the grid. In the past, most engineers thought that the drivers supporting energy recovery were too expensive. However, with the rising cost of energy, these systems are now considered cost-effective. High-efficiency equipment can be used for equipment including mine cranes and cranes that load ships.
Multipurpose, programmable digital servo driver
Servo drives are also changing. Previously, drives were controlled using analog signals via a centralized controller or a connected digital controller. These units are then digital-analog converted. Most modern drivers are all digital, which means that the feedback signal is a digital signal, the control signal is also digital, and the driver can be equipped with a digital signal processor. Therefore, the user can configure the drivers as "dummy drivers" that acquire commands from a centralized control location and provide digitized handshake information such as the position and speed of the driver. Older drives require a lot of additional hardware. In contrast, today's drives are easier to configure and can perform multiple tasks through a single package.
Open loop vector control system with higher accuracy
Open-loop vector control systems are also undergoing changes. They have been greatly improved over older "V/F" drives. Open-loop vector systems provide better accuracy and speed control than V/F systems, as well as better torque characteristics. Current AC drives can use sensorless vector controlled permanent magnet servo motors and more traditional squirrel cage induction motors. This system is smaller in size but provides higher torque and power. In addition, this technology has a faster dynamic response, and permanent magnet motors stop and start faster than motors that must produce two fields. This layout has low cost and high performance characteristics suitable for low power applications.
More powerful cooling
Drive cooling methods are also constantly changing and developing. Typically, most drives use air-cooling methods. However, in recent years, in high power applications, refrigerant cooling methods have been used to take away the heat generated by IGBTs. This cooling method allows the driver to provide more power in a smaller space while reducing IGBT thermal cycling. For example, Parker developed and patented an advanced two-phase cooling system that can be integrated into high-power drivers with extremely high power density.

Resetting
If an abnormal display appears or the buttons produce no response, the instrument must be reset. To do this,
press the RESET button.
Display Mode
Entire LCD can be displayed for about 1 minute and then it automatically gets into Model. To transfer from
one mode to the other, press the FUNCTION button.
Mode 1: Time/Watt/Cost Display Display duration(how long) this device connect to power source.LCD on first line shows 0:00 with first two figures mean minutes(2 figures will occur while occur at 10 min) and the rest shows seconds. After 60mins, it displays 0:00 again with first two numbers meas hour(2 figures will occur at 10hours)and the rest shows minutes.
