The development of the CH2000 series is rooted in Delta's years of technical accumulation and in-depth understanding of industrial needs. Unlike ordinary frequency converters on the market, the CH2000 is positioned for high-end heavy-duty applications, integrating multiple advanced technologies such as magnetic field-oriented control and EtherCAT motion control bus. It supports both induction motors and permanent magnet motors, and can provide customized solutions for different industries such as cranes, machine tools, and printing machinery. This article will delve into the technical background, core features, application scenarios, and practical performance of the Delta CH2000 inverter, helping readers fully understand the product value and application potential of this high-performance vector inverter.

Technical Background and Product Positioning

The industrial sector's demand for frequency converters has been evolving in recent years. With the continuous improvement of automation and intelligence, traditional low-power, low-precision frequency converters can no longer meet the requirements of heavy-load equipment such as cranes, high-precision machine tools, and printing machinery. These application scenarios often face challenges such as instantaneous impact loads, high overload requirements, and precise motion control, which put forward higher requirements for the torque output, response speed, and control accuracy of frequency converters.

Against this background, Delta Electronics launched the CH2000 series high-performance vector inverter based on new-generation drive technology. Its product positioning is clear: to provide a reliable drive solution for impact loads and heavy-load applications. According to official product information, the R & D of the CH2000 focuses on improving starting torque, overload capability, and motion control performance, aiming to solve the problems of unstable operation and easy tripping of traditional frequency converters under heavy load conditions.

Compared with other products in Delta's inverter product line, the CH2000 has obvious advantages in high-power motion control. It supports a complete set of motion control solutions formed by the combination of EtherCAT motion control bus and Delta's self-designed high-efficiency servo motors. With the motion control card EMC-MC01, it can support cyclic synchronous position mode (CSP) and cyclic synchronous torque mode (CST), which lays a foundation for high-precision motion control applications. In terms of power coverage, it can match Delta's MSJ series high-power high-efficiency servo motors from 15kW to 80kW, meeting the drive needs of most medium and large industrial equipment.

Core Performance Advantages

The core competitiveness of the Delta CH2000 inverter lies in its excellent performance indicators, which are particularly prominent in three aspects: overload capability, torque control, and motor adaptability.

First of all, in terms of overload capability, the CH2000 series is designed as an extra-heavy-duty product, which can achieve 150% of the rated output current for 60 seconds and 200% for 3 seconds. This index is much higher than that of ordinary industrial frequency converters, which can easily cope with the impact load generated when the equipment starts, brakes, or changes working conditions. For example, in crane applications, when the hook starts and lifts heavy objects instantaneously, it will produce a large impact on the motor. The high overload capability of the CH2000 ensures that the equipment can still operate stably under this working condition, avoiding frequent tripping and shutdown caused by overload protection.

Secondly, the starting torque performance of the CH2000 is remarkable. According to product specifications, it can output more than 200% of the rated torque at 0.5Hz, and in the FOC+PG closed-loop control mode, it can output 200% of the rated torque at 0Hz. This large starting torque characteristic is crucial for heavy-duty starting scenarios. For example, in the starting stage of a machine tool spindle or a crane lifting mechanism, it can provide sufficient torque to ensure that the equipment starts smoothly without jitter or stalling.

In terms of motor adaptation, the CH2000 supports both induction motors and permanent magnet motors, which reflects its high flexibility. Different types of motors have different control characteristics, and the CH2000 achieves high-precision control of two different types of motors through magnetic field-oriented control technology. In the closed-loop control mode with encoder (FOCPG), the speed control ratio can reach 1:10,000, which means that it can still maintain high-precision speed control at very low speeds, meeting the needs of high-precision processing applications.

In addition, the CH2000 also has some user-friendly design features. It has a built-in 10K steps PLC, which can realize simple logic control functions without external PLC, reducing the cost of the control system. The application of low-noise modulation technology reduces the electromagnetic interference and noise generated during operation, which improves the working environment of the equipment. In terms of motion control, the support of EtherCAT bus realizes high-speed real-time communication, which meets the requirements of multi-axis coordinated motion control in modern industrial equipment.

Special Function Design for Typical Industries

The Delta CH2000 inverter not only has general high-performance characteristics but also develops targeted special functions for typical application industries, which is one of its important competitive advantages.

The most representative is the targeted function development for crane applications. Cranes are typical heavy-load impact-load equipment, which has strict requirements on the safety and stability of the drive system. The CH2000 integrates a variety of special crane functions: full-time anti-sway function, which can effectively suppress the shaking of the heavy object during the movement of the trolley, improve the efficiency and safety of hoisting operations; rope looseness detection function can detect the abnormal state of the wire rope in time to avoid accidents; light hook acceleration function optimizes the operating efficiency when the hook is unloaded; double main hook synchronization function realizes the coordinated operation of two hooks, which is suitable for large-weight hoisting working conditions; deviation correction function ensures that the movement trajectory of the crane is accurate and avoids position deviation.

These special functions have been verified in a large number of practical applications. According to industry users, after using the Delta CH2000 inverter with crane-specific functions, the shaking of the crane hook is significantly reduced, the positioning accuracy is improved, and the safety of hoisting operations is effectively enhanced. At the same time, because these functions are integrated inside the inverter, there is no need to add additional external control modules, which simplifies the system design and reduces the failure rate.

For machine tool and printing machinery applications, the high-precision speed control and fast response characteristics of the CH2000 are also fully adapted. In the spindle drive of CNC machine tools, the CH2000's 1:10,000 speed control range and high torque output capability at low speeds ensure that the spindle can maintain stable speed under different cutting conditions, which is conducive to improving the surface processing quality of the workpiece. In printing machinery, the stable speed control and fast dynamic response of the CH2000 ensure the synchronization accuracy between different printing units, avoiding the problems of overprinting deviation and paper breakage, and improving the qualification rate of printed products.

In practical debugging cases, the CH2000 also shows good adaptability to synchronous motors. In an on-site debugging case of an extrusion molding equipment shared by industry technicians, the CH2000 successfully realized stable control of the synchronous motor by selecting the FOC+PG control mode, solved the problem of abnormal operation of the original old frequency converter, and restored the normal production of the equipment. This case reflects that the CH2000 has good compatibility and adjustability in different motor and application environments.

Main Application Fields and Case Analysis

Based on its performance characteristics, the Delta CH2000 inverter has been widely used in many industrial fields, and the main application areas include the following three categories:

The first is the crane and hoisting equipment industry, which is also the most important application field of the CH2000. Due to the targeted design of its crane-specific functions, many crane manufacturers have chosen the CH2000 as the drive solution for the operating mechanism and lifting mechanism. Take a port container crane project as an example. The project uses multiple CH2000 inverters to drive the lifting mechanism and trolley traveling mechanism. After years of operation, the system has maintained stable performance. The full-time anti-sway function reduces the shaking of the container during transportation, improves the loading and unloading efficiency of the port, and reduces the safety risk caused by container shaking. The high overload capability of the CH2000 adapts to the frequent heavy-load starting and braking working conditions of the crane, and the failure rate is much lower than that of the previously used ordinary frequency converters, reducing the maintenance cost of the equipment.

The second is the machine tool manufacturing industry. High-precision CNC machine tools have very high requirements for the spindle drive system, requiring both large torque output at low speeds for heavy cutting and high-speed stable operation for finishing. The CH2000's performance just meets this requirement. A well-known domestic machine tool manufacturer has equipped the spindle of its heavy-duty CNC milling machine with the Delta CH2000 inverter. In practical use, when performing heavy cutting of large workpieces, the large starting torque and high overload capability of the CH2000 ensure that the spindle does not stall, and the cutting process is stable. In finishing, the high-precision speed control improves the surface finish of the workpiece, and the overall processing accuracy meets the design requirements. Compared with the imported inverter solution used in the past, the CH2000 not only has comparable performance but also significantly reduces the procurement cost of the equipment.

The third is the printing and packaging machinery industry. Printing machinery requires multiple units to coordinate operation, and the speed synchronization accuracy between units directly affects the printing quality. The high-response speed control capability of the CH2000 and the support of the EtherCAT motion control bus ensure the synchronization accuracy between each unit. A large packaging enterprise upgraded the drive system of its flexographic printing press, replacing the original ordinary frequency converter with the Delta CH2000. After the upgrade, the overprinting accuracy of the printing press was significantly improved, the problem of overprinting deviation that occurred when the speed changed in the past was solved, the product qualification rate increased from 92% to 98.5%, and the production efficiency also increased by about 10%, bringing obvious economic benefits to the enterprise.
