CI Systems SR-800R
6.2.9 RA
Summary : This command retrieves the current target position from the selected
axis. As long as the selected axis is in motion, then the command will return the
last selected target position. Once the axis stops its motion, then the command will
return the new current position of the target. Use the
GetAxisStatus command to
query axis motion.
This is a multifunction command supporting the old style SR80 BlackBody
command format and has been expanded to support new functionality for the SR-
800R.
In its base form, no operands are needed. It will return the current target position
of
Axis1 in the system.
In its expanded form it uses a single operand to determine which axis to retrieve
the information from.
If no axes are present in the system, then it will return an
Operand Error . Use the
GetNumberOfAxes Command to query for axes in the system prior to using this
command.
SR-80 command format compliance.

Input Operand : None or 1 AxisNumber = A value from 1 to 4 representing the
axis to be accessed.
Return Values : The command returns the current target position number for the
requested axis. This can be a value from 1 to the number of Targets in the desired
axis.
Example : Assume system with 2 axes and they are connected to Axis1 and Axis2 ;
(Target Wheel and Filter Wheel), then the command will respond to the following
scenarios:
•
Axis1 is motion from Target 2 to Target 5.
•
The Host sends a RA 2 or just the RA command. The response will be 2 .
•
Axis1 stops its motion, and then its response will be 5 .
•
Axis1 and Axis2 are in the system and the user uses the RA 3 command. The
response will be Operand Error.
