Siemens offers new features in the firmware and hardware for the Sinamics S120 drive system. Operation is made much easier in firmware V5.2 through the integration of the web server. The web server in version V5.2 has a new, responsive design, which reacts via standard web browsers regardless of the end device used (notebook, PC, tablet or smartphone). For commissioning typical diagnostics and maintenance functions or servicing, no special tools are required. The web pages are available in six standard languages and feature error indicators and warning messages including meaningful help texts and suggestions for possible solutions. Users can intuitively create, manage and delete parameter lists—even across axes—and can perform firmware updates and system restores with the old firmware version. Backups of parameter settings can be stored on the clients using the web server and browser, and reloaded in the Sinamics converter using the Restore function. In order to test functions that are subject to license, it is possible to activate a temporary trial mode. In addition, a complete overview of all functions that are subject to license is clearly displayed in the web server. For optimum display on any Internet-capable end device, the best browsers are Microsoft Edge, Mozilla Firefox, Google Chrome and Safari. Navigation is via menu or breadcrumbs.
In terms of hardware, Active Line Modules (ALM) can now be connected in parallel for the Sinamics S120. The new firmware V5.2 provides the user with an extended performance range for booksize versions. The parallel connection also results in increased rated power without an additional chassis unit or an external power connection. The power can therefore be increased and voltage peaks are overcome. In addition, energy exchange is possible in the DC link. The new features are available for 55, 80 and 120 kilowatt (kW) ALMs and can also be used in external smart mode.
