In order, to keep the telescope tracking the field of view selected, the instrument will need to a rotation system for compensating it . The new WEAVE  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|
