S220

System architecture with a central Control Unit

Electronically coordinated individual drives work together to perform your drive tasks. Higher-level controllers operate the drives to achieve the required coordinated movement. This requires cyclic data exchange between the controller and the drives. This exchange usually took place via a field bus, which required a great deal of time and effort for installation and configuration. SINAMICS S220 takes a different approach: A central Control Unit controls the drives for all connected axes and also establishes the technological links between the drives and/or axes. Since all the required data is stored in the central Control Unit, it does not need to be transferred. Inter-axis connections can be established within a Control Unit and easily configured in the STARTER commissioning tool using a mouse.

• Simple technological tasks can be carried out automatically by the SINAMICS S220 Control Unit
• The CU320‑3 PN Control Unit is suitable for multi-axis applications
• Sophisticated Motion Control tasks can be implemented with the support of high performance motion controllers such as the Simatic S71500T (technolgy) CPUs, or Sinumerik controllers for Machine Tool Applications. 

SINAMICS S220 standard firmware that contains all of the most popular control modes and can be scaled to meet even the highest performance requirements.

The drive controls are supplied as ready-to-configure drive objects:

• Infeed Control for line infeed
• Vector Control
  • Variable-speed drives with high speed and torque stability in general machine and plant construction
  • Particularly suitable for induction motors
  • Optimized pulse patterns for efficient motor/converter systems
• Servo Control
  • Drives with highly dynamic motion control
  • Angular synchronism with isochronous PROFINET
  • For use in machine tools and clocked production machines
