当高方位角望远镜在特定视场进行跟踪时，需要使用去旋转系统来补偿地球对视场的旋转。为了使望远镜跟踪选定的视场，仪器将需要一个旋转系统来补偿它。新的WEAVE[2] 2度视场需要在望远镜的顶端安装一个新的视场去旋器。旋转系统设计了一个直接驱动电机，消除了对机械传动元件的需要，如齿轮箱、减速机和蜗轮传动。这种设计在系统性能和寿命方面具有巨大的优势，因为它消除了诸如长时间漂移、弹性和反弹等不良特性。采用罗克韦尔伺服驱动和控制器开发了硬件控制系统。旋转器必须由高级软件控制它也负责望远镜的控制。本文总结了为模拟而开发的模型和将用于接收旋转系统的软件。还进行了一项性能研究，以测试CIP（通用工业协议）在高级软件和旋转器硬件之间的通信。
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.
