Simplified servo drive systems from Siemens

Posted 15 March 2018

The Sinamics S210 converters from Siemens are designed specifically for use with the Simotics S-1FK2 motors, in order to offer simplified servo drive systems in five power classes ranging from 50 to 750 watts. The functional scope of the Sinamics S210 focuses on highly dynamic motor axis control. The converters come with integrated safety functions and enable rapid engineering.

They are connected to higher-level controller over Profinet and allow simple commissioning using a web server and one-button tuning. The connected controller takes complete charge of positioning functions for the connected drive axes. Working in combination with Simotics servo motors, the converters enable highly dynamic movements of minimal loads, as well as ultra-precise movement of medium and high loads.

The motors are connected to the converters using a One Cable Connection (OCC), grouping together power conductors, encoder signal and brake in a thin cable measuring just 9 mm in diameter, and using a single plug. The connecting plug comes in a rugged design despite being rotatable and easy to operate at a height of 25 mm. The integrated safety functions include STO (Safe Torque Off) and SS1 (Safe Stop 1). Both can be actuated using PROFIsafe, STO additionally using a terminal.
