(ZRM)
The ADU has the following identical ZRMs, one for each drive wheel
(each axes):
•X Elevation ZRM
•Elevation ZRM
•Azimuth ZRM
The ZRM has a Hall sensor that detects a zero point (small magnet,
mounted on the drive wheel). The zero point signal of the ZRM is sent
to the PCM and is used in the orientation of the ADU.
For step-by-step instructions see:
