The newly developed CU305 Control Unit forms the basis of the drive functionality and intelligence of the Sinamics S110. It is available with Profibus DP or CANopen interfaces. This also enables the single-axis converter to be quickly and flexibly integrated into various automation structures, and retrofitting projects make integration into existing architectures easy. A Basic Operator Panel (BOP) can be added to the Control Unit for operating and diagnosing the device. The type PM340 Power Modules are the same size as the existing Sinamics S120 AC/AC series, making them compatible for configuration and connection. That facilitates system-wide solutions and also simplifies spare part inventories. The Power Modules are blocksize format, available in frame sizes FSA to FSF and a 0.12 to 90 kW power range. The Power Modules are suitable for connection to both grounded and non-grounded networks.
One of the key functions of the Sinamics S110 is the integrated basic positioner (EPos). Classic positioning functions, such as relative and absolute traversing with specified velocity and acceleration, can thus be realized just as quickly as more complex functions, such as on-the-fly positioning and referencing. The user can save up to 16 target positions or traverse paths in the drive, including the relevant motion parameters. The individual traversing blocks can be brought together in traversing programs. Target positions and velocities as well as additional motion parameters can be changed at all times, even during a positioning traverse. The in-built monitoring of traversing range limits, following error and standstill indicate possible overrunning or malfunctions in good time, and thus make a significant contribution to the high level of operational reliability of a machine driven in this way.
