W) ServoLoop Error LEDs
(One Red LED per axis for Four Red LEDs in total)
These four red LEDs light to show errors in each of the ServoLoops.
You can identify which ServoChannel is having a problem and the type of
error by counting the 'blink code' on these LEDs:
1) One blink = Following Error. The servo loop isn't able to follow the
position commanded by the Show Control System within the
allowable tolerances or time.
2) Two blinks = Position Feedback voltage below allowable limit. You
set the allowable range of travel as you are doing the initial
ServoLoop setup. If it goes outside of this range, it is an indication
that there is something wrong with the Position Feedback sensor
or wiring to it. This could indicate a break in one of the Position
Feedback wires (typically the positive reference, it using a three
terminal potentiometer).
3) Three blinks = Position Feedback voltage above allowable limit.
You set the allowable range of travel as you are doing the initial
ServoLoop setup. If it goes outside of this range, it is an indication
that there is something wrong with the Position Feedback sensor
or wiring to it. This could indicate a break in one of the Position
Feedback wires (typically the negative reference, it using a three
terminal potentiometer).
X) ServoLoop Position Feedback LEDs
(One Green LED per axis for Four Green LEDs in total)
These four Green LEDs show the scaled input level on all four of the
voltage inputs from the position feedback sensors. This should also be a
fairy accurate representation of the position commands from the Show
Control System. You will see these LEDs fade in and out as the signals on
the inputs change. These LEDs are not directly connected to the analog
outputs. They are scaled to reflect the ‘minimum’ and ‘maximum’ endpoint
settings. If the command from the Show Control System calls for the
output at 0%, the LED will be off. If it asks for 100%, it will be fully on.
Y) ServoLoop Compliance Feedback LEDs
(One Yellow LED per axis for Four Yellow LEDs in total)
