FI (Binary D6)
FUNCTION: Find Index
DESCRIPTION:
The FI and BG commands move the motor until an encoder index pulse is detected.
The controller looks for a transition from low to high. When the transition is
detected, motion stops and the position is defined as zero. To improve accuracy,
the speed during the search should be specified as 500 counts/s or less. The FI
command is useful in custom homing sequences. The direction of motion is
specified by the sign of the JG command.
ARGUMENTS: FI XYZW Where
X,Y,Z,W specify XYZ or W axis. No argument specifies all axes.

Hint: Find Index only searches for a change in state on the Index. Use FE to search for the Home.
Use HM (Home) to search for both the Home input and the Index. Remember to specify BG after each
of these commands.
