RC2000A Dual Axis Antenna Controller
these values not be changed from the default values. The provision to modify these parameters is
included for those customers who use the azimuth and elevation drive outputs from the RC2000A to
drive a pair of 36 volt relays (equipped with steering diodes) which in turn activate AC motors. More
information about using the RC2000A in this fashion may be found in the appendix entitled "Controlling
Antennas Powered by AC or Large DC Motors with the RC1000 or RC2000 Antenna Controllers".
Access to the CONFIG mode items described in this chapter is permitted only when the Expert Access
Flag is set.
The Az/El Drive Options Enable CONFIG mode item is the controlling item for the other CONFIG mode
items described in this chapter. When this item is disabled the user does not have access (via CONFIG
mode) to the other items described in this section. Note that when this item is disabled, the current
values of the other items described in this section are used to control azimuth and elevation movement.
In other words, disabling this item does not reset the other items described in this section to their default
values.
AZ/EL DRIVE OPTIONS ENABLE:0
0-DISABLE, 1-ENABLE
During an automatic move in AUTO mode, the 'Fast Slow Threshold CONFIG mode items are used to
set the number of counts before a target position is reached that the controller switches the speed of the
drive from fast to slow. There is a separate value for each axis.
AZIM FAST SLOW THRESHOLD: 80
0-400 COUNTS
ELEV FAST SLOW THRESHOLD: 80
0-400 COUNTS
During an automatic move in AUTO mode, the 'Coast Threshold CONFIG mode items set 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 counts 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
counts of the target position.
AZIM COAST THRESHOLD: 4
1-40 COUNTS
ELEV COAST THRESHOLD: 4
1-40 COUNTS
The 'Max Position Error CONFIG mode items set the maximum acceptable error between the final
resting position and a target position for an automatic move which occurs in AUTO mode.
AZIM MAX POSITION ERROR: 1
0-10 COUNTS
