Product Description
The AMC102 is a Eurocard-sized two-axis motion controller bringing unique features to
both traditional Azimuth/Elevation and X-Y type tracking heads. The system has been
designed from the ground up with performance in mind. Unlike some other controllers,
the system can perform axis tracking whilst executing other tasks such as host
command invocation (including position requests), time and station position
determination and the normal limit sensor monitoring.
Servo Motor Control Processor
The AMC102 is a stand-alone unit which directly interfaces to servo motor amplifiers,
axis position encoders and axis limit sensors. The AMC102 incorporates separate servo
motor tracking loops for each axis and is controlled by a host computer via a single
RS232 (or RS422) serial port interface.
All tracking events, including position requests, are time tagged with a resolution of
1mS. The AMC102 can accept commands and return axis information whilst
simultaneously performing all tracking functions. The system has a look-ahead table
driven mode of tracking which supports host machines which are not able to process
requests in real time.
A brief summary of the controller's capabilities are listed below:-
•
Twin Axis - stackable.
•
Fast axis tracking response (less than 2mS tracking loop time per channel).
•
On board profile generator for object tracking and manual control modes (10mS
update rate).
•
Time tagged position requests (1mS resolution).
•
Time tagged current position returns (1mS resolution).
•
Differential quadrature encoder inputs for axis position determination.
•
GPS resolution of station position and time (UTC).
•
Independent differential voltage feeds for servo amplifiers (12 bit DAC).
