Fully digital form of frequency converter control system
With the development of computer technology, the inverter industry has seen improved digital management and a greater reliance on digitalization. The integration of computers, industrial networks, and motor drives is a perfect combination, reflecting a current trend in industrial development. To enhance the performance of AC motor drive systems, it is essential to implement fully digital control.
In the era of fully digital AC speed control, various fieldbus technologies have emerged that integrate with automation systems, such as PROFIBUS, DEVICENET, MODBUS, and CANBUS, significantly reducing on-site installation, commissioning, maintenance, and failure rates. Remote fault diagnosis and Teleservice maintenance technologies are integrated into the frequency converters. Teleservice technology enables remote monitoring functions, such as historical data statistics and fault reports. It also allows for remote maintenance of the frequency converter, including parameter setting and adjustment when a new frequency converter is connected, fault location and troubleshooting, and routine monitoring and management. Siemens Masterdrive frequency converters and Fuji motor frequency converters support Teleservice functionality.
The development of this industry, and the effects of its fully digital form, have become significant. However, the industry's development cannot be changed by these effects alone. This is one aspect of the industry's development, and it has gradually become a form of speed control in this industry.
