n 0x8E00-01 = 3n Signal corresponds to the signal of an incremental encoder. By direct connection to apower stage synchronous axes in the master/slave structure can be realized.n A1 (A) and A2 (B) output a phase-shifted by 90° signal.n The shift from A1 to A2 is positive for clockwise rotation and negative for counter-clockwise rotation.4.1.2 Structure of a positioning controlThe figure below shows the structure of a typical positioning controlThe Control consists of the PLC with the user program for the processing and the motionmodule to control the power stage. The control of the power stage happens via RS422signals. You can define a software limit switch in the motion module and react in the userprogram on the overrun.The power stage receives from the motion module the corresponding control commandsand controls automatically the connected motor. A motor is a engine for high-precisionpositioning. Motor and power stage are to be harmonizedCAUTION!Please provide for track limits (general position limit) respectively to avoiddamages besides software limit switch hardware limit switches and alsoconsider this in your safety concept.Incremental encoder simu-lation (A/B)StructureControlPower stage with motorVIPA System SLIODeploymentBasics > Structure of a positioning controlHB300 | FM | 054-1DA00 | en | 18-0644
