Motion control functions
The SIMATIC S7-1200 offers positioning functionality for controlled and position-controlled axes. This allows stepper motor drives, frequency converters or servo drives to be operated at the S7-1200 via the integrated pulse interfaces, analog outputs or PROFINET / PROFIBUS. Incremental position encoders can be read in via the integrated high speed counters.
Further functions are absolute and relative movements, referencing and jogging mode as well travel profiles for stepper drives. All functions can be mapped easily with the PLCopen-conform Motion Control function blocks that are contained in the SIMATIC STEP 7 Basic Engineering System.
