USB Fieldbus systems & interfaces USB USB (Universal Serial Bus) is a serial bus system for connecting a computer to external devices. As such, it was not developed for networking in an industrial system – unlike the industrial fieldbuses – but primarily for the consumer sector. In industrial applications, USB is normally only used for the parameterization and diagnosis of devices. Nanotec offers a number of controllers/drives and motors with integrated controller/drive that are equipped with a USB interface. The controllers/drives are detected immediately as mass storage devices without the use of additional drivers and enable the parameterization of the controllers/drives via a configuration file. With the free Plug & Drive Studio software it is also possible to parameterize and diagnose the controllers/drives via any PC. For this purpose, the software installs an additional driver for a virtual serial interface (VCP – Virtual Com Port) via which the data can be sent with the Modbus RTU protocol. Nanotec offers motor controllers/drives as well as brushless DC motors and stepper motors with integrated controller/drive and USB interface. Controllers/drives with USB Motors with USB
