The CONFIG-AZ PULSE screen contains items for configuring automatic movements based on sensor
count (resolver or pulse) azimuth position feedback.

The antenna_azim_constant configuration item specifies the approximate number of pulses measured
per radian of azimuth travel. See installation section 2.4.4 for calculation of the azimuth pulse scale
factor.

CCW:
AZIM CCW PULSE LIMIT <0 - 32768>
The cw_azim_pulse_limit and ccw_azim_pulse_limit configuration items specify the range of azimuth
motion measured in pulses. These items are used by the tracking and autopeak algorithms to place
bounds on the area searched. These values are also used to determine the validity of stored satellite
data.

FAST/SLOW:
SET THRESHOLD <0 - 999 PULSES>
During an automatic move, the azim_fast_slow_pulse_threshold configuration item is used to set the
number of pulses before a target position is reached, when the controller switches the speed of the drive
from fast to slow.

from fast to slow.
MAX ERROR:
SET MAXIMUM ERROR <0 - 10 PULSES>
The azim_max_position_pulse_error configuration item sets the maximum acceptable error between the
final resting position and a target position during an automatic move.
final resting position and a target position during an automatic move.
COAST:
SET COAST RANGE <0 - 999 PULSES>
During an automatic move, the azim_coast_pulse_threshold configuration item sets the number of pulses
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 Error of the target position.

TRIES:
SET MAX NUMBER OF TRIES <0-10>
The azim_auto_move_max_retry_pulse_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.
