CIntroduction

1 Introduction

The M-116 rotary stages all feature high-precision, preloaded

worm-gear drives (zero-backlash gear-head with M-116.xxH

versions) that allow unlimited rotation in either direction. All

versions have a non-contact optical reference switch and/or

optional custom limit switch outputs (with some limitation on

travel range, if present). The DC motor versions are equipped

with optical encoders whereas the stepper motor versions are

designed to operate in open-loop mode only.

The DC motor/gearhead versions are equipped with shaft-

mounted encoders. The gear ratio of 29.6 to 1 is used for

increased resolution.

The stepper motor versions use microstepped 2-phase stepper

motors with 1200 microsteps/revolution. Because stepper

motors are driven to specific positions with known accuracy,

these units are open-loop only.
