Driven by consumption promotion and product diversification, the manufacturing industry's demand for automation and intelligent promotion in production and processing is also increasing. In the production process, the processing of "large and heavy" items is often difficult to control accurately, and the error of orientation is not as easy as that of "small" items. To this end, Delta has recently officially launched the MZM, a high-power azimuth drive system for shopping malls, which combines the characteristics of high power and precise positioning, and can meet the needs of precise positioning in the power scale of 15-80 kW, and then break through the constraints of high-power azimuth drive shopping malls.
Shi Wenxiang, product director of Delta-Zhongda Dentsu inverter, said that most of the directional drive demand in the industrial field is concentrated in the small power scale, and the shopping mall often thinks that it is difficult to achieve both high power and accurate control. Conventional inverters can complete hundreds of kW of high power, and the bandwidth is fundamentally lower than 40 Hz, which is not accurate; The general servo has a bandwidth of 1-3K, and it is no problem to complete accurate control at low power, but it is difficult to adhere to the stability of the function when the power gradually increases. With the expansion of automation work, Delta has also seen some shopping malls that have practical use needs, such as punch punching and flying saw equipment for building materials, centrifuges and CT instruments for medical applications, and large-scale stage lifting equipment, which often require drive control plans with sufficient power and accurate control. Delta's MZM high-power azimuth drive system came into being, which has the characteristics of both high power and precise positioning, and is a powerful tool for high-power azimuth drive.
Delta's MZM high-power azimuth drive system integrates the functions of Delta's heavy-duty vector control inverter CH2000 series, high-power servo motors, bus cards, and motion control cards. The MZM high-power azimuth drive system is concentrated in the power scale of 15-80 kW and can achieve an output torque of 48-520 N. The accuracy of 1500 RPM and 17 bit is enough to complete the needs of accurate control. For the use of fixed-length and fixed-distance motion control of punching machines, flying saws, conveyors, winding machines, forming machines, etc., Delta's high power and accurate control not only fully match the needs of the scene, but also present it in the form of a complete drive system, ensuring the stability of the system from the source, and then giving customers a greater competitive advantage.
The motor control center algorithm carefully developed by Delta is the key to the success of MZM's high-power azimuth drive system. MZM supports CSP, CST, CSV, HM and other forms, which can meet the needs of various sports forms; The product also has the function of ASR gain self-adjustment, which makes the control process more refined and smooth under the exquisite control of the central algorithm. Even at low frequencies, torque shake control is guaranteed to be within ±1.6%. Taking the centrifuge in the medical profession as an example, this use not only has a large load and high control accuracy, but also has a strict constraint on the torque fluctuation of the system. Delta's MZM system, on the other hand, can complete the positioning accuracy of a pulse while running stably, and the speed fluctuation during positioning does not exceed 1 RPM.
Similarly, in use scenarios that require more fine control, such as CT machines, large-scale analyzers, and rotary table grinders, Delta's MZM also has weak competitiveness.
User-friendly operation and easy to use for commissioning
Taking into account the convenience of device commissioning, MZM is able to directly identify the matching motor type and automatically obtain its parameters and optimal control strategy. Without the need for human intervention, the characteristics of the motor can be fully utilized.
The MZM is also equipped with special engineering assistance software, which makes the system adjustment, diagnosis, and monitoring intuitively visible. The commissioning of the equipment can be completed quickly, which will save customers more time and benefits.
Occupation uses function modules to improve the ease of use of products
For typical use scenarios of target occupations, such as punch manufacturing process, steel plate manufacturing process, etc., Delta has also developed corresponding special function modules for MZM, which can be used for positioning control, fixed length and fixed distance, etc., greatly shortening the equipment development time, and improving the ease of use of the product through the modular feature of function blocks.
High degree of integration Easily build an integrated plan
Combined with Delta's PC-Based Motion Controller AX series, multi-axis motion controller DVP-MC series, human-machine interface, and integrated programming software, the product can easily build a complete set of system solution plans to ensure system compatibility and stability.
