III. Operating Environment Conditions
The normal operating temperature range of the product is from 0 degrees Celsius to 55 degrees Celsius. The storage temperature range when the equipment is powered off is from -20 degrees Celsius to 70 degrees Celsius. The air humidity in the usage environment should be maintained within 5% to 95%. During use, no condensation or water accumulation is allowed. The product has excellent anti-vibration and anti-shock capabilities and can adapt to the regular mechanical vibration conditions in industrial workshops. The usage site should be away from strong electromagnetic radiation sources, strong corrosive gases, large amounts of dust, and oil accumulation areas to avoid the impact of adverse environments on the controller's service life and operational stability.
IV. Electrical Power Supply Parameters
The standard working power supply of the controller is 24 volts DC, supporting a voltage fluctuation of ±10%. The controller is equipped with a complete reverse connection protection, overvoltage protection, and short-circuit protection circuit, which can effectively avoid hardware damage caused by wiring errors and unstable voltage. The overall operating power consumption is low, and the power supply current load is small. It can be stably powered using a conventional industrial DC power supply. The internal circuit of the controller and the external input and output signal circuits achieve high-voltage electrical isolation, with a high isolation protection level, significantly reducing the risk of circuit crosstalk and leakage faults in the field.
V. Core Hardware Performance
The controller is equipped with an industrial-grade high-performance real-time main control chip, combined with a hardware acceleration computing architecture. The program operation efficiency is high, and the system runs without lag. It supports ultra-short cycle real-time control operations and can achieve microsecond-level precise action responses. It has a large-capacity program storage area and data storage area, which can store large control programs, multiple sets of equipment production formulas, operation history data, and equipment parameter information, meeting the program storage and data retention requirements for multiple processes and multiple modes of equipment. It strictly follows the IEC61131-3 international industrial programming standard and supports multiple mainstream industrial programming languages for program writing. The programming and debugging are convenient, compatible with industry-standard programming logic, and is compatible with the programming habits of most automation equipment.
VI. External Function Interface Configuration The body is equipped with two independent industrial Ethernet communication interfaces, which can be connected to different communication network segments respectively. It fully complies with mainstream industrial Ethernet communication protocols such as EtherCAT, Profinet, and Modbus TCP, and can simultaneously connect human-machine interfaces, servo drives, remote monitoring systems, and third-party compatible industrial control equipment, achieving signal intercommunication and remote network control for the entire equipment. It also comes with a serial communication interface, supporting RS232 and RS485 communication modes, and can be connected to various sensors, detection instruments, and external auxiliary control devices on-site, enabling low-speed signal acquisition and simple equipment linkage control. The controller comes with a dedicated backplane expansion bus interface, which can seamlessly connect all expansion modules of the same series, freely expand digital input/output, analog signal acquisition/output, temperature acquisition, and high-speed counting functions, and flexibly expand hardware points according to the equipment's functional requirements. The body integrates multiple status display indicators, corresponding to power-on status, system operation status, fault alarm status, and communication connection status. When the equipment has an abnormality, it can quickly locate the fault category.
VII. Core Product Functions
It has complete industrial logic control functions, capable of completing the start-stop linkage of the entire equipment, sequential operation of the process, and external signal interlock triggering. It integrates professional-level motion control functions, supporting multi-axis synchronous operation, electronic gear linkage, cam action control, linear and circular trajectory interpolation, and multi-closed-loop regulation of position, speed, and pressure, precisely controlling the equipment's action rhythm and running accuracy, and is suitable for control of hydraulic drive, servo drive and other power equipment. It comes with device data acquisition and parameter management functions, capable of real-time collection of various running data such as equipment temperature, pressure, speed, and stroke, supporting one-click parameter retrieval and one-click formula switching, facilitating the rapid switching of production processes. It has built-in industrial equipment safety control functions, in line with industrial equipment safety operation standards, capable of achieving emergency shutdown, safe speed limit, and operation position protection safety control functions, providing comprehensive safety guarantees for on-site production operations. It supports remote program upload and download, online real-time program monitoring, fault code reading, and remote viewing of equipment operation status, greatly reducing the difficulty of on-site equipment debugging and later maintenance.
VIII. Main Application Domains
This controller has strong comprehensive performance and is widely applicable. It is primarily used in all series of vertical and horizontal injection molding machinery to complete precise control of the entire molding process, such as mold closing, injection, holding pressure, cooling, and ejection; it is also widely used in die-casting machinery, hydraulic stamping equipment, extrusion machinery, and other rubber and metal forming machinery; it can also be used in industrial multi-axis automated assembly lines, high-speed packaging sorting equipment, automotive parts processing automation equipment, lithium battery and photovoltaic industry automation production equipment, and various large-scale industrial intelligent equipment. It is the preferred main control component for mid-to-high-end industrial automation equipment.
IX. Installation and Usage Specifications
During installation, it should be fixed on the standard guide rail of the control cabinet. Adequate ventilation and heat dissipation space should be reserved around the controller. Do not stack densely to cover the heat dissipation area, and keep away from frequency converters, large-power motors, and other strong electromagnetic interference components. During on-site wiring, strictly distinguish the positive and negative poles of the power supply, communication lines, and power lines. Separate the strong and weak current lines, and use shielded cables for communication signal lines. The shielding layer should be single-point grounded according to the specification to reduce external signal interference. Before powering on, carefully check whether the wiring is firm and there are no short circuits or misconnections. Only after confirming that the wiring is correct can the equipment be powered on for debugging and operation. During daily use, regularly clean the accumulated dust on the controller surface, check if the interface lines are loose or aged, and when the equipment is in a long-term idle state, disconnect the power supply, place it in a dry and ventilated environment for proper storage.
