Shutdown

The Shutdown signal is passed through to the motion controller and is
typically used to disable the controller. Refer to Figure 3-17 for the pin
locations of the Global Stop connector and to Table 3-6 for the
corresponding signals for each pin. Refer to Figure 3-1 to locate the Global
Stop connector on the UMI-7774/7772.

Both the Shutdown and Inhibit All inputs are sinking inputs on the
UMI-7774/7772 and are optically isolated. The Shutdown interface circuit
is shown in Figure 3-16. The interface circuit is the same for the Inhibit All
input. You can wire the Shutdown and Inhibit All inputs to a sourcing
output device, such as a PNP sensor, as shown in Figure 3-16. You can use
the isolated power (V
iso
connector to power the sensor.
Refer to the Voltage Considerations for the UMI-7774/7772
voltage information that applies to the global stop wiring.
The UMI-7774/7772 has a single 9-pin D-SUB connector that provides
access to the four analog input channels on the motion controller. The
analog inputs are pass-through signals on the UMI-7774/7772. Refer to
