8-4. Position Data Reading Setting

8-4-1. Position Data Reading by Latch Pulse (LP) Output

Position data reading is synchronized with the LP output signal from the converter.
The reading format is selectable from the following three: edge timing, level timing 1, and level timing 2.
(1) Edge timing
The position data output is updated when the LP signal switches from ON to OFF. It stabilizes when the LP
signal switches from OFF to ON, so the position data should be read at that time.

The above figure indicates when LP signal logic setting is non-inverted.
The LP signal logic can be inverted. For more details, refer to the "8-4-2. Output Logic of Latch Pulse
(LP) Signal Setting".
