Motion feedback controler
- January 27, 2021
The LIC 3100 absolute kit encoder, a new offering that fits between Heidenhain’s LIC 4100 and 2100 series, is tolerant to contamination and has very loose mounting tolerances.
The graduation of the LIC 3100 encoder is carried by a sturdy stainless-steel tape. This steel tape scale has a 2-track graduation resulting in a period of 80 microns. The tape scale is offered in rolls at 3m, 5m, and 10m lengths and can be inserted into an aluminum extrusion for better thermal growth behavior, or can be mounted directly to the motion axis surface with an adhesive backing on the steel tape.
The reader head of the LIC 3100 can output a measuring step of 10 nanometers and maintain a velocity of 10 meters-per-second. Compatible with five different high speed serial electrical interfaces makes this unit plug-and-play. The interpolation error, or cyclical error, is +/- 100 nanometers, allowing the encoder to provide smooth, constant velocity and allows linear motors to function more efficiently.
Mounting of the reader head to the scale is fast and simple due to forgiving mounting tolerances and easy-to-use handheld diagnostic tools. A zero-datum position can be programmed anywhere along the scale length.
