System architecture with a central control module
Each electronic collaborative driving device can work together to complete the user's driving task. The upper controller can generate the required coordinated motion of the driving device. This requires cyclic data exchange between the controller and all driving devices. So far, this data exchange must be achieved through a fieldbus, and the installation and design costs are correspondingly high. On the other hand, the SINAMICS S120 variable frequency speed cabinet adopts a different approach: a central controller drives and controls all connected shafts, and technical logical interconnection can also be achieved between driving devices or between shafts. Since all required data is stored in the central controller, these data do not need to be transmitted. Cross axis connection can be achieved within one controller, utilizing A mouse can be easily configured using the STARTER debugging tool
The SINAMICS S120 variable frequency speed control cabinet controller can automatically perform simple technical functional tasks
CU310-2 DP or CU310-2 PN control units can be used for single machine drive
CU320-2 DP or CU320-2 PN control units are suitable for multi axis applications
With the help of SIMOTION D's more powerful control units D410-2, D425-2, D435-2, D445-2, and D455-2 (graded by performance), complex motion control tasks can be completed

These control units are all based on the object-oriented SINAMICS S120 standard firmware, which includes all the most commonly used control modes and can be upgraded to meet the highest performance requirements
Drive control is provided in the form of easily configurable drive objects:
Incoming rectification control
vector control
Variable speed transmission devices with high precision and torque stability in general machine and factory structures
Especially suitable for asynchronous (induction) motors
Pulse mode optimized to achieve efficient motor/frequency converter systems
servo control
High dynamic response motion control
Angle synchronization with isochronous PROFIBUS/PROFINET
Can be used for machine tools and production machinery
The most commonly used v/f control mode is stored in vector control drive objects and is suitable for performing simple applications, such as group drive using SIEMOSYN motors
CompactFlash card
The functions of the SINAMICS S120 driver are stored on the CF card. This storage card contains firmware and parameter settings (in the form of a project) for all driver devices The CF card can also save additional items, which means that when debugging different types of series machine tools, the correct items can be accessed immediately. After the control unit is started, the data on the CompactFlash storage card is read and loaded into RAM
Firmware is organized in the form of objects. Driver objects are used to perform open-loop and closed-loop control functions on input modules, motor modules, power modules, and other system components connected through DRIVE-CLiQ
Driver object
A driver object is an independent software function with its own parameters and, if necessary, its own fault messages and alarms
Extend process functions through SIMOTION
The SIMOTION D control unit supports coordinated motion control of multiple drivers. In addition to the driving objects, process objects can also be implemented on these control units. These objects can be grouped to form process function packages and provide extended motion control functions (such as synchronous operation, camshaft, path interpolation, etc.) or process functions (such as cam controller, temperature or pressure control) SIMOTION D integrates a PLC that complies with IEC 61131-3, which means that the system can not only control motion sequences, but also control the entire machine including HMI and I/O
