Auxiliary Encoder Input Signal Types
Auxiliary Encoder Interface
All encoder input signals (CN1B) are filtered using analog and digital
filtering, including illegal state change detection.
The input circuitry includes pull-up and pull-down resistors for
compatibility with single-ended and open collector signals, in addition
to differential signals.
Figure 2.25 shows the configuration of the AX Auxiliary Encoder Input
channel. The BX and IX channels have the same configuration.
