FI (Find Index)
[Motion]
DESCRIPTION:
The FI and
combination moves the motor until an encoder index pulse, or “C” channel, 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 1000 counts/s or less. The FI command is useful in custom homing sequences. The direction of
motion is specified by the sign of the
