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:

• Extended synchronous operation functions
  • Synchronization with specification of the synchronous position
  • Actual value linkage
  • Shifting of the master value at following axis
  • Camming
• Cam disk
• Up to 4 encoder or measuring systems as actual position for position control
