Page 42: Glossary
Each limit switch sends its signal to the controller on a dedicated line. The controller then interrupts the motion avoiding that the positioner moves until the hard stop and gets damaged. PI positioners have mechanical, noncontact optical or Hall effect limit switches. Linear Encoder The linear encoder is an incremental sensor for detecting changes in position. - Page 43 L412UM0003EN ‒ 10/24/2022 Sensor Resolution The sensor can be the critical element of position resolution so it may be necessary to specify the sensor resolution separately. Rotary encoder: Impulses per screw rotation. Linear encoder: Smallest motion still detected by the sensor system. Specifications The performance specifications are checked before dispatch.
