Issue Date: | 2018 | Volume: | Ground-based and Airborne Telescopes VII | Editors: | Marshall, Heather K.; Spyromilio, Jason | Series: | PROCEEDINGS OF SPIE | Number: | 10700 | First Page: | 1070033 | Abstract: | When an alt-azimuth telescope is tracking at a specific field, it is necessary to use a de-rotator system to compensate the Earth's rotation of the field of view. In order, to keep the telescope tracking the field of view selected, the instrument will need to a rotation system for compensating it [1]. The new WEAVE [2] two degrees field of view requires a new field de-rotator on the top-end of the telescope. The rotator system has been designed with a direct drive motor which eliminates the need for mechanical transmission elements such as gearboxes, speed reducers, and worm gear drives. This design is a huge advantage for the system performance and lifetime because it eliminates undesirable characteristics such as long-time drift, elasticity, and backlash. The hardware control system has been developed with a Rockwell servo-drive and controller. The rotator has to be controlled by the high-level software which is also responsible for the telescope control. This paper summarizes the model developed for simulating and the software which will be used to accept the rotator system. A performance study is also carried out to test the CIP (Common Industrial Protocol) for communications between the high-level software and the rotator hardware. | Conference Name: | Ground-based and Airborne Telescopes VII | Conference Place: | Austin, Texas, United States | Conference Date: | 10-15 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/28171 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10700/2313238/The-hardware-control-system-for-WEAVE-at-the-William-Herschel/10.1117/12.2313238.short | ISSN: | 0277-786X | ISBN: | 9781510619548 | DOI: | 10.1117/12.2313238 | Bibcode ADS: | 2018SPIE10700E..33D | Fulltext: | open |
