CHARACTER DISPLAY AND LEDS
The MACRO Station has a single hexadecimal character display on the CPU/Interface Board that
provides useful information as to the status of the station. The display indicates how many motors are
activated and displays certain types of failures that might occur. One unique feature on the display is the
LED dot in the bottom left corner. When this LED is illuminated, that means 8 must be added to the
number being displayed. For example, if the display reads 4 and the LED dot is illuminated, that would
mean that there are 12 axes enabled at the 16-Axis MACRO CPU. The display can show the following
values:
Value Meaning
(Blank) Ring not active
0-8 Operation OK; value is # of motors enabled
9 (Reserved for future use)
A Amplifier fault
B Ring break fault
C CPU failure fault
D Ring data error
E Loss-of-encoder fault
F Other failure
Dot Add 8 to the number of enabled Axes
# Activated
Axes +8
# Activated Axes
Note:
The display can be read at the Ultralite with MI974. This is useful especially for
user interface programs and for systems that are in inconvenient locations to read
the display.
