LEDS
Axis 0 LED
Axis LED applies to the Drive 0 output or feedback input 0 as described below:
1. If Drive 0 is assigned to an axis that has an input (i.e. isn't output-only), then that
axis will own the Axis 0 LED.
2. Otherwise, if a reference input axis (no output) uses input 0, then that axis will own
the Axis 0 LED.
3. Otherwise, if Drive 0 is assigned to an output-only axis, then that axis will own Axis 0
LED.
Axis 1 LED
Axis 1 LED applies to the Drive 1 output or feedback input 1 or 2 as described below:
1. If Drive 1 is assigned to an axis that has an input (i.e. isn't output-only), then that
axis will own the Axis 1 LED.
2. Otherwise, if a reference input axis (no output) uses input 2, then that axis will own
the Axis 1 LED.
3. Otherwise, if a reference input axis (no output) uses input 1, then that axis will own
the Axis 1 LED.
4. Otherwise, if Drive 1 is assigned to an output-only axis, then that axis will own the
Axis 1 LED.
