SINAMICS G: Speed Control of a G120 (Startdrive) with S7-1200 via PROFINET/PROFIBUS DP with Safety Integrated (via Terminal) and HMI

  • Entry
  • Associated product(s)
SIMATIC S7-1200 can be operated as PROFINET controller as well as PROFIBUS master (with CM 1243-5). A SINAMICS G110M or G120 shall be connected as as PROFINET device or as PROFIBUS slave. The PLC shall have read/write access to the process data and parameters of the drive.



This application example includes a PROFINET project and a PROFIBUS project. It exemplarily demonstrates how to connect a SINAMICS G120C PN or a G120C DP to a SIMATIC S7-1200. The drive integration into the STEP 7 program is done in TIA portal by means of the StartDrive Option Package. In the PROFINET version, loading the configuration into the drive is done via Ethernet, in the PROFIBUS version via USB.

By the used function blocks...

  • you operate the drive via its contol word and set a speed setpoint.
  • you read the drive's status word and its actual values of speed, current, torque, fault, alarm.
  • you exemplarily read/write the drive parameters ramp-up time and ramp-down time.
  • you read parts of the fault buffer.

You can apply the function blocks directly with your own applications.
