Installation and Configuration

2.8.2. High-Speed Differential Inputs (J8)

The high-speed inputs can be used as general purpose I/O or as auxiliary encoder input channels (such as
for velocity feedback or the MPG option or other handwheel device).
Auxiliary Encoder
The high-speed inputs can be used to provide up to two additional channels of quadrature encoder inputs.
These auxiliary encoder channels can be used as the velocity feedback device for a dual-loop system (but
cannot be used for position feedback due to the lack of marker input). The auxiliary encoder inputs can also
be used with the MPG option or other hand wheel type devices.
