Emergency Stop Sense Input (TB101)

If you purchased the -AUXPWR option, the opto-isolated input (PS2806-1 device)
activates by an external fail-safe emergency stop circuit. It is not intended to be an
emergency stop circuit in itself. It is scaled for a 24 volt input voltage, or a 5 volt input by
changing JP6 as shown in the following table. Using a higher input voltage requires
adding an external series resistor to limit the current.
If the ESTOP bit is enabled in the FaultMaskGlobal axis parameter (see the Soloist Help),
the ESTOP input must be driven to prevent the ESTOP fault condition.
For typical ESTOP wiring, see the following schematic and interface drawing.

 Connecting the E-Stop input to a relay or other noise producing device/circuit,
requires one or more noise suppression devices, such as those in Table 2-5, or other
appropriate devices.
