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 volt DC logic signals. The pin assignment for the connector is shown in the table
below.
Alternatively, opto-isolated user inputs 8-10 may be used as the end-of-travel limit
inputs, see Section 3.1.3.
See Table 3-12 for the mating connector part number.
