ESTOP Connector
This 2-pin connector provides a pair of contacts that can be used for a Breakaway E-Stop
function at the end of the arm. See
Table 7-5 . The function is disabled by default when the
system is shipped. The user must enable this function using the SPEC program (see
below), and connect a normally-closed circuit to Pins 1 and 2. When the circuit is opened,
the system will stop in an E-Stop condition. See
Figure 7-7 .
