Overview
2.1 Introduction
The PRM1-Z7 is a precision motorized rotation mount for 1" optics.
Rotation is driven via a DC servo motor equipped with high ratio gearbox (256:1) and
rotary encoder for accurate closed loop position control. The TDC001 DC servo
controller is the ideal companion for achieving smooth continuous motion which can
be measured both through the software interfaces and by using the Vernier dial and
1° engraved graduation marks on the rotating plate. The precision DC motor actuator
provides 1 arcsecond resolution over the 360° rotation. This rotation stage is also
equipped with a precision home limit switch to facilitate automated rotation to the zero
datum position, allowing absolute angular positioning thereafter.
The limit switch is designed to allow continuous rotation of the stage over multiple
360° cycles. For complete flexibility the stage can be mounted either vertically on a
post or horizontally using an adapter plate - see Section 3.2
