3.3.1.3.5 Elevation Angle Movement

The CONFIG-EL ANG screen contains configuration items for calibrating large automatic elevation
movements based on angle (inclinometer or resolver-based) position feedback. See the Drive System
theory section 4.3.3.
FAST/SLOW: 2.5
MAX ERROR:0.20
FAST/SLOW THRESHOLD <0.0-10.0 DEGREES>
FAST/SLOW:
During an automatic move, the elev_fast_slow_threshold configuration item is used to set the number of
degrees before a target position is reached when the controller switches the speed of the drive from fast
to slow.
MAX ERROR:
The elev_max_position_error configuration item sets the maximum acceptable error between the final
resting position and a target position during an automatic move.
COAST:
During an automatic move, the elev_coast_threshold configuration item sets the number of degrees
before the target position is reached where the drive will be deactivated. The idea is to deactivate the
drive and let the antenna coast into position. If prior to the initiation of the move operation the total
number of degrees that the actuator has to move to reach the target position is less than the 'Coast
Threshold, the drive will be deactivated when its position is within 'Max Position Error of the target
position.
TRIES:
The elev_auto_move_max_retry_cnt configuration item sets the maximum number of attempts which will
be made to hit a target position (within Max Error - described above) during an automatic move based
on potentiometer feedback.
COAST:0.5
TRIES: 3
FAST/SLOW THRESHOLD <0.0-10.0 DEGREES>
MAX ERROR <0.01 - 1.00 DEGREES>
COAST RANGE <0.0 - 2.0 DEGREES>
MAX NUMBER OF TRIES <0-10>
