7.4.1. Encoder Interface

The encoder interface requires square wave signals from a line driver differential output
encoder. Figure 7-6 illustrates the encoder phasing with relation to motor rotation.

Additionally, as part of each encoder interface, there are inputs for marker signals that are
received by a differential input comparator circuit. These signals are standard on
incremental encoders and provide a reference point for the mechanical system driven by
the BAI. The maximum encoder input frequency is 2.5 MHz (theoretically). The
minimum edge separation is 1/10MHz.

Figure 7-6.

7.4.2. Limits Interface

Three limit inputs are incorporated into the BAI, the first two are end-of-travel limits and
the third is the home limit. The end-of-travel limits are designated as “CWlimit” and
“CCWlimit”. Clockwise (CW) motor rotation is inhibited by the “CWlimit”, while
counterclockwise (CCW) is inhibited by the “CCWlimit”. Refer to Figure 7-7 for limit
switch circuitry.
