Motor feedback systems - Import export

In rotary table applications, maximum precision counts when it comes to workpiece positioning. The exact mounting of the target wheel has a considerable influence on the achievable positioning accuracy, especially if the wheel has a small diameter. Thanks to the new i³SAACPrecisionSystem from Lenord+Bauer, this can now be significantly improved. The system also offers advantages for precise spindle speed control. • i3SAACPrecisionBox as part of the system for the minimisation of the eccentricity error • Increasing the system accuracy of incremental measuring systems • Ability to replace M23 connectors • Easy commissioning with the testing and programming unit GEL 211C • Function with standard MiniCODERs

The compact, highresolution MiniCODERs from Lenord+Bauer have proven their value for speed and position acquisition in highly dynamic applications. They use their full potential when installation situations with little space require a particularly compact, robust and reliable measuring system. The magnetic measuring systems consist of a ferromagnetic target wheel and a scanning unit. Without dedicated bearings, they are completely wearfree and maintenancefree. The optimised circuit and screening technique, and fully encapsulated electronics ensure reliable operation even in harsh environments. High measuring accuracy and compact design have made MiniCODERs the most frequently used speed sensors in highspeed spindles in the world. More than 500,000 pieces are installed, among other things, in machines for highspeed cutting. They are suitable for speed and position detection in all highly dynamic applications and offer now also digital motorfeedback.

Magnetic motor feedback systems are proving themselves in numerous applications in linear drive technology, handling systems, circuit board assembly, robotics and in a wide range of automation solutions in the context of Industry 4.0. In all of these areas, the speed and/or position of a drive must be communicated to a main controller in real time. The ultra compact LEC100 and LEC200 sensor duo has been developed by SIKO for these requirements. Repeat accuracy max. ±1 μm. max. resolution 0.2 µm (LD output circuit). Reading distance ≤0.2 mm. Works with MB100/1 magnetic tape. Signal period 1000 μm. Output circuit sin/cos or LD. Function and status display LEDs.
