3.3.1.3.8 Polarization Drive
The CONFIG-POL DRV screen contains configuration items for calibrating polarization movements based
on potentiometer position feedback. See the Drive System theory section 1.3.7.
CONFIG-POL DRV
FAST/SLOW: 2.0 COAST: 0.3
MAX ERROR: 0.10 TRIES: 3
SET THRESHOLD <0.0-10.0 DEGREES>
FAST/SLOW: SET THRESHOLD <0.0-10.0 DEGREES>
During an automatic move, the pol_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: SET MAXIMUM ERROR <0.01 - 1.00 DEGREES>
The pol_max_position_error configuration item sets the maximum acceptable error between the final
resting position and a target position during an automatic move.
COAST: SET COAST RANGE <0.0 - 2.0 DEGREES>
During an automatic move, the pol_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.
RETRY: SET MAX NUMBER OF TRIES <0-10>
The pol_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.
3.3.1.3.9 Pol Drive Monitoring
This group performs the same functions for the polarization axis as described in 3.3.1.8 (Azimuth Drive
Monitoring)
