7.8 External Gating Logic Index
A typical circuit for gating the Index signal with the encoder A & B channels is shown in the
following schematic.
Comments on Schematic
In order for proper operation of the Index signal when used for position capture or phase correction,
the signal must be gated with the A & B encoder channels to ensure that this signal is only active
when all three signals are LOW. The motion processor does not perform this gating internally.
