RC4500 Antenna Controller Chapter 5 MODES – In Depth Descriptions
99
The CONFIG-AZ COUNT screen contains items for configuring automatic movements based on sensor
count (resolver or pulse) azimuth position feedback.
5.2.1.3.3 Azimuth Count Movement
CONFIG-AZ COUNT
FAST/SLOW: 50 COAST: 3
MAX ERROR: 1 TRIES: 3
FAST/SLOW THRESHOLD <0-999 COUNTS>
FST/SLW: FAST/SLOW THRESHOLD <0 - 999 COUNTS>
During an automatic move, the azim_fast_slow_pulse_threshold configuration item is used to set the
number of counts before a target position is reached when the controller switches the speed of the drive
from fast to slow.
MAX ERROR: MAXIMUM ERROR <0 - 10 COUNTS>
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.
COAST: COAST RANGE <0 - 999 COUNTS>
During an automatic move, the azim_coast_pulse_threshold configuration item sets the number of counts
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: 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 pulse count feedback.
