Siemens Energy & Automation’s Sinamics S110 single-axis ac servo drive is said to be easily commissioned, highly flexible, and conveniently connected to higher-level controllers.

Designed for simple positioning or indexing applications with synchronous or induction motors, the new drive offers unique motor-choice flexibility that normally is not offered with simple servo drives. Operating in the 0.12 to 90 kW power range, the drive features a wide array of positioning functions as well as integrated safety. Profibus, Profinet (in preparation), CANopen or analog/digital interfaces allow the Sinamics S110 to be easily integrated into a Siemens Simatic automation system, and into multiple other higher-level controllers.

The Sinamics S110 servo drive can be used for simple pick-and-place and feeding tasks, as well as with rotary indexing tables. It is also suitable for robotic and handling applications, feeders in printing and paper machines, and for ejectors in injection molding machines. Other applications include tool positioning in machining stations and positioning task in the wind and solar industry.

An integrated basic positioner (EPos) enables a wide range of positioning functions, ranging from relative and absolute traversing with specified velocity and acceleration to more complex functions, such as on-the-fly positioning and referencing. As a result, it is possible to save up to 16 target positions or traverse paths in the drive, including the relevant motion parameters. Additionally, individual traversing blocks can be brought together in traversing programs. Target positions and velocities, as well as additional motion parameters, can be changed on the fly, even during a positioning traverse. All of the positioning functions are easily configured graphically.

The unit has seven on board safety functions, which meet the safety requirements of category 3 as defined in EN 954-1 and Safety Integrated Level 2 as defined in EN 61508. The safety functions are controlled via three safe inputs and one safe output (terminals) on-board the S110. When integrated into a total automation system, it can also be controlled via the Profisafe profile.
