Scalability

SIMATIC Drive Controller offer the required flexibility and performance for a wide range of
controller applications in machine and plant engineering.
Scaling with performance class
To meet your machine and plant planning requirements, the SIMATIC Drive Controller can be
scaled in terms of CPU and Motion Control performance and configuration limits (program
and data memory and Motion Control resources).
The comprehensive networking options over PROFINET and PROFIBUS DP are the same for all
versions. This means that you can scale simply by CPU performance – without affecting the
available interfaces and thus your machine and plant topology.
Scaling with drive configuration limits
SINAMICS S120 automatic speed control is integrated in all versions of the SIMATIC Drive
Controller. It can control.
• A max. of 6 servo drives; or
• A max. of 6 drives with vector control; or
• A max. of 12 drives with U/f control
You can expand the drive configuration limits of a SIMATIC Drive Controller, for example with
SINAMICS S120 (CU320-2) or SINAMICS S210 (for example for individual drives). In this case,
the CPU axis technology objects execute the Motion Control functions for the SINAMICS
Integrated drives and drives connected externally. The maximum axis configuration limits are
limited at the CPU side by the available Motion Control resources.

In principle, you can connect any drives that:
• Support the standardized profile for PROFIdrive drive technology
• Support the PROFIdrive frames possible with SIMATIC S7-1500
