Electrical switching & drive systems & components
Siemens has extended its basic servo drive system, consisting of the Sinamics V90 converter and the Simotics S-1FL6 servo motor, to serve a much wider field of application. The basic servo drive system is now available with 200 volt converters and motors with lower shaft heights and lower moments of inertia. This is in addition to the familiar 400 volt versios with a higher moment of inertia in the servo motor. The 200 volt converters are up to 25% smaller than the 400 volt version and therefore save additional space in the control cabinet.
With a total of eight converter sizes and seven motor shaft heights with a power range from 0,05 to 7,0 kW, the system is suitable for service in single- and three-phase networks. Thanks to the lower moments of inertia of the motors, a wide range of motion control tasks can be realised in a cost-efficient manner. Here the focus is on dynamic motion and processing – for example positioning, transporting and winding in a wide range of applications.
Numerous integrated functions such as pulse train input positioning, USS/Modbus connection, internal positioning ,as well as speed and torque control enable users to reduce their machine costs. A braking resistor has been integrated as standard to improve dynamic performance. Furthermore, the servo converter also features a rapid pulse train input of up to 1 MHz and supports absolute encoders with a 20 bit resolution. These functions give the system a high level of fast positioning accuracy and a low level of speed ripple. The improved servo performance is made possible by a number of features, including the threefold overload capacity of the Simotics S-1FL6 servo motor and the optimally coordinated combination of motor and converter as Integrated Drive Systems (IDS). Using IDS-based drive technology, Siemens boosts productivity, energy efficiency and reliability in all automation environments and throughout the entire lifecycle.
The Sinamics V90 is also characterised by its outstanding ease of use. For example, the Sinamics V-Assistant software tool, which is available as a free download, supports commissioning, engineering and diagnosis of the converter. Intuitive menu navigation gives a clear overview of the commissioning procedure. Thanks to coated electronic modules in the Sinamics V90 and a protection rating of IP65 for the Simotics S-1FL6, the drive system is extremely rugged – even in difficult ambient conditions. The integrated Safe Torque Off (STO) safety function prevents the motor from rotating unexpectedly, thereby improving safety for both machine and operator.
