Accessories optional items for the attoMOTION Premium Line Materials & Sizes For selecting the right choice for the application, the main criterion is certainly the type of output (as described before) as well as the number of positioners to be wired. Flanges: Connection: Select between KF or CF flanges with 40 mm, or 63 mm diameter, respectively. Open loop positioners require two electrical lines, resis- tive encoded positioners (/RES) five, and optoelectronic encoded positioners (/NUM+) are equipped with a SubD15 connector per axis. Consequently, the number of required SubD15 flange feedthroughs vary depending on the positioner type, e.g. a standard SubD15 connector can be used to ei- ther connect a single /NUM+ encoded positioner or three / RES encoded positioners. Electrical feedthroughs: Depending on the flange size either one or three SubD15 feedthroughs are integrated into the flange. Cabling: Each VFT package includes all cables necessary to connect the positioner with the controller through the flange. An adapter cable at ambient pressure (length: 2m) is used to connect the controller to the flange. Inside the vacuum chamber attocube uses only Kapton-insulated wires together with connectors made from PEEK. Depending on the package the cable will be made from woven flat (NUM) or two (open loop) respectively two and three (RES) twisted pair wires. attoMOTION Piezo-based Nano Drives PAGE 331
