Paper Abstract

This paper explores the use of direct drive servos in telescopes applications in the quest of standardization key concepts that might push to more reliable and cheaper solutions for future complex motion systems. Considerations related to different PWM Frequencies, Motor Phasing, position feedback, CAN-bus interfaces, etc. A collection of data from the VLT experience is presented showing the particular needs of the modern telescope’s drives. Can an industry standard amplifier meet the telescope specifications, and therefore be easier to maintain and offer a cheaper solution?
