All SIMATIC S7-1500 CPUs support motion control functions. STEP 7 provides motion control instructions that are standardized in accordance with PLCopen for configuring and connecting a drive to the CPU.
Motion control with the S7-1500 supports the following technology objects:

  • Speed-controlled axes
  • Positioning axes
  • Synchronized axes (relative synchronism with synchronization, without specification of the synchronous position, setpoint linkage)
  • External encoders
  • Cams
  • Cam track
  • Probe

The technology CPUs of the SIMATIC S7-1500 offer advanced motion control functions:
