AZIMUTH SYSTEM CONFIGURATION
Each Axis of the RC2800PRKX2SU needs to be configured for a spectrum of use and position of limits. The
programmable limits in the RC2800PRKX2SU control, give the ability to specify the amount of travel around a
spectrum of use. The AZ and EL 2 axis positioner has physical limits CCW / DWN and CW / UP. The limits
provide physical stops for safety due to control box failure. The CCW / DWN or CW / UP limits also create a
reference return for each axis when using the "Auto cal" feature during Remote/computer or manual control.
Below we have provided a visual explanation of some common axis configurations complete with suggested
electrical and physical limits and spectrum of use.
CW PHYSICAL LIMIT –.6°
CW ELECTRICAL LIMIT –.3°
VIEWED FROM THE
TOP OF THE SYSTEM
LOOKING DOWN
CCW ELECTRICAL LIMIT 70°
CCW PHYSICAL LIMIT 60°
Characteristics: Azimuth (S-Center)
Spectrum of use: + 360°
Over travel amount: 12°
SU Designation: Azimuth (S-center)
OVERVIEW:
This azimuth configuration may be used when
360° of travel is necessary with primarily a
southern exposer and avoids limits where most
of the operations are being preformed. Note the
position of the Physical limit switches, they are
on the outside of the electrical limits. Ultimately,
this provides safety when and if a control box
fails.
CCW PHYSICAL LIMIT –.357°
CCW ELECTRICAL LIMIT –.349°
Characteristics
Spectrum of use: 240°
Over travel amount: 20°
SU Designation: Azimuth (S-center)
OVERVIEW:
This azimuth configuration may be used when
less than 360° of travel is necessary with a
CW ELECTRICAL LIMIT 290°
southern exposure and avoids limits where most
of the operations are being preformed. Note the
position of the Physical limit switches, they are
on the outside of the electrical limits. Again, this
CW PHYSICAL LIMIT 300°
provides safety when and if a control box fails.
