The following items set the controller's CW and CCW polarization limits when a rotating feed is
installed. The procedure to determine these limits is given in section 3.3. Note that the CW
limit must by definition be less than the CCW limit.

Motor Drive Options

The CONFIG mode items described in this section set the automatic movement parameters for
the drive. The default values of these parameters (as initialized upon System Reset) are
adequate for use with 36 volt linear actuators. For systems employing linear actuators, it is
recommended that these values not be changed from the default values. The provision to
modify these parameters is included for those customers who use the drive's output from the
CONTROL-1500 to control a 12-36 volt relay (equipped with a steering diode) which in turn activates
a larger AC or DC motor. Contact RCI for more information about these applications. Access to
the CONFIG mode items described in this chapter is permitted only when the Expert Access
flag is set.
The Auto Move Cnfg 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
antenna movement. In other words, disabling this item does not reset the other items
described in this section to their default values.

AUTO MOVE CNFG:0
0-NO, 1-yes
During an automatic move in AUTO mode, the 'Fast Slow Threshold CONFIG mode 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.
