3.3.1. End of Travel Limit Inputs
Two of the three limit inputs are end-of-travel sensing (CW Limit and CCW Limit) while
the third is a reference limit (Home Limit). All of the end of travel limit inputs accept 5-
24 VDC logic signals. The Pin Assignment for the connector is shown in the table below.
See Table 3-12 for the mating connector part number.
Alternatively, opto-isolated user inputs 8-10 may be used as the end-of-travel limit inputs
(see Section 3.1.3).
