Intelligent machining solution plan
In order to help manufacturers improve productivity or complete a small number of diverse production forms, Delta will exhibit the intelligent processing solution plan at TIMTOS x TMTS 2022, which will build a ring network with high-end high-speed multi-ring network redundancy technology ONE RING PLUS through the industrial-grade managed Ethernet switch DVS series, and connect intelligent lathes, machining centers, and grinding machines to the IT layer through the equipment networking channel DIALink. In combination with DIAMMP, DIAEnergie and DIAView, the company provides useful information that can be used to make decisions and plans.
Intelligent CNC architecture
In response to its integration into the Industry 4.0 factory ecosystem, Delta has also proposed a new intelligent CNC architecture when it launched the NC5 series of next-generation CNC manipulators, with CNC manipulators as the center and connecting Delta's rich products in series. With the significant upgrade of hardware specifications and performance, the NC5 series supports the open EtherCAT universal motion bus, with high compatibility and cable lengths of up to 1,000 meters, which can integrate Delta's communication servo drive system ASDA-A3 / ASDA-B3 series and I/O modules R2-EC / R1-EC at high speed and stability to form a complete processing plan. In addition, Delta also provides the NC3 series of CNC manipulators, which can be connected to the ASDA-A3/S series of communication servo drive systems in series according to DMCNET high-speed communication motion control, and integrate high-speed series optical coupling I/O NC-EIO with Remote I/O. Both plans can be equipped with a communication ring encoder RHM or a pulse encoder EH5. In addition, according to different operational needs, Delta has also launched the new CNC touch display NC-MOT series, touch PC-based industrial manipulator PAC/MP1 series and CNC second operation panel NC-PAN for easy use by customers.
Five-axis machining center
In the face of industrial space and manpower challenges, high-efficiency processing equipment has become a common demand for machinery manufacturers to break the predicament, among which the five-axis processing equipment that can process messy workpieces at one time is an important solution that has attracted much attention in the field of machine tools. In this regard, during the TIMTOS x TMTS 2022 period, Delta built a five-axis machining center for the machine operator Danemec, centered on the newly launched OPEN CNC controller NC50E, which not only completes the "one machine with multiple tasks" of simultaneous multi-channel operation, but also integrates Delta's new vertical multi-joint robot DRVA4LC which is a new product in the field of industrial robots for automatic loading and unloading, and the RTCP function is controlled by rotating the tip of the tool, which can complete five-sided machining in one clamping. Completed high-precision and high-speed composite machining. Not only that, but with the DRVA4LC with a maximum load of 12 kg and a maximum working radius of 1,400 mm, it can also meet the needs of multiple handling applications such as high loads and large strokes.

The cause of inverter heating - Delta inverter
1. The problem of the inverter and the motor itself
If the motor has been used for a long time, it is not good to clean the insulation function, or the bearing may be stuck, and it may show a large current and heat. The coupling between the motor and the load may also be worn, or the motor is unbalanced, the fixtures of the motor are loose, etc.

Several veins of the inverter circuit - Delta inverter
1. Vibration circuit: the leakage-source and R4 of the main winding N1 and Q1 of the switching transformer are the channels of the power supply operation current; R1 provides the starting current; The self-powered windings N2, D1, and C1 constitute the power supply voltage of the vibrating chip. The normal operation of these three links is the prerequisite for the power supply to vibrate.
