Comments
Attempts Position Error counts of a target position.
Az/El Fast Deadband 4000
milliseconds
The controller will allow 4 seconds for the antenna to
coast to a stop. If RUNAWAY errors occur the value of
this parameter can be set to 4001 to disable the
accumulation of counts when the antenna is not
commanded to move or is not coasting to a stop. This will
disable the RUNAWAY error.
Az/El Slow Deadband 4023
milliseconds
The controller will allow 4 seconds for the antenna to
coast to a stop. The last two digits (‘23’) tell the controller
to not schedule a peakup when Step Tracking within 230
seconds of a time corresponding to a Program Track table
entry. This prevents ‘holes’ from occurring in the program
track table. See the troubleshooting section of the RC2000
manual for more information.
Azim Coast Threshold
and Elev Coast
Threshold
14 position
counts
When moving towards a target position in either azimuth
or elevation, the controller will turn off the motors when
the position reaches a point 14 counts away from the target
position. The idea is that the antenna will coast into
position.
Azim Max Position
Error and Elev Max
Position Error
8 position counts This parameter is used when the controller is attempting to
automatically move the antenna in azimuth or elevation to
a target position. If (after a move) the resting position of
the antenna is greater than 8 counts from the target
position the controller will initiate another auto move to
attempt to hit the target position if the number of retry
attempts initiated so far is not greater than that specified
by the Az/El Auto Move Retry Attempts CONFIG mode
item.
Antenna Size 380 centimeters
Azim Constant 17492 counts per
radian
This is the approximate number of position counts per
radian of antenna azimuth movement. This corresponds to
305 azimuth position counts per degree.
Elev Constant 33615 counts per
radian
This is the approximate number of position counts per
radian of antenna elevation movement. This corresponds
to 587 elevation position counts per degree.
Max Track Error 5 tenths of a dB
Search Enable 0-DISABLE For transmit applications the search feature should be
disabled. Please see the description of TRACK mode in
the RC2000 manual for more information.
