EDH0242En1010 — 03/10 2 URB100CC High-Speed Belt-Driven Rotation Stage 2.0 Description The URB100CC rotation stage is based on our popular URS series, but features a belt drive instead of a worm gear. The belt drive offers significantly higher rotation speeds of up to 720 °/s without sacrificing life time expectancies. Typical applications are LIDAR, 3D imaging, or film thickness measurements of semiconductor wafers. Common to these applications are fast rotations over larger angles or continuous spinning at very high duty cycles and with high precision requirements with regards to wobble,...

3 EDH0242En1010 — 03/10 URB100CC High-Speed Belt-Driven Rotation Stage 3.0 Characteristics 3.1 Definitions Specifications of our products are established in reference to ISO 230 standard part II “Determination of the position, precision and repeatability of the machine tools with CNC”. This standard gives the definition of position uncertainty which depends on the 3 following quantities: (Absolute) Accuracy Difference between ideal position and real position. On-Axis Accuracy Difference between ideal position and real position after the compensation of linear error sources. Linear errors...

EDH0242En1010 — 03/10 6 URB100CC High-Speed Belt-Driven Rotation Stage 5.4 Feedback Signal Position The incremental shaft encoder consists of a optical scale and an encoder head. When the sensor shaft turns, the encoder head generates square signals in quadrature, sent to pins #19, #20, #23 and #24 of the 25-pin Sub-D connector. Encoders are “differential pair” (type RS422) type output signals. Using these signals permits a high immunity to noise. Emission circuits generally used by Newport are 26LS31 or MC3487. Reception circuits to use are 26LS32 or MC3486 respectively. Pin #21 Pin #22...
