■
The encoder must be an incremental encoder.
■
The encoder must have a RS-422/TTL interface. In the case of strong magnetic
fields in proximity to the TriSpectorP1000, use a recommended encoder (no.
1068997) to ensure optimal performance.
■
The connection requires two encoder channels (A/A¯ and B/B¯) to keep track of
movement and direction.

Encoder modes
The forward scanning direction is defined as a clockwise encoder shaft movement,
as seen from the tip of the shaft. There are five encoder pulse counter-modes: posi‐
tive/negative movement, forward/backward movement and bidirectional.
