SIMATIC S7-1200 / 1500: Encoderless Positioning with SINAMICS G
SIMATIC S7-1200 and S7-1500 automation systems support the controlled positioning of electrically driven axes. Technology objects are used for this purpose.
Communications to the SINAMICS drive system is established via standard telegrams according to the PROFIdrive profile. The motion control intelligence is embedded in the SIMATIC, where an application-specific setpoint profile is generated. The drive follows this setpoint profile, and position deviations are compensated using the position controller integrated in the SIMATIC.
The subsequent application example provides the following encoderless positioning functions:
- Absolut or relative Positioning
- Jog and setting-up operation
- Active as well as passive referencing
- Linear- and rotary axis
Basic positioning axes with low demands placed on the positioning accuracy
Feeder and transport axes in conveyor systems
Compensation of speed dips when loads are transferred/transitioned; for example, for conveyor belts running one after the other
Position tracking functionality for conveyor systems
Feeding packages into sorting systems
