.
Alternately, the first SS_Out output may be used to signal a programmable logic
controller (PLC) that a Safe Stop has been requested.
If the SS_In is ON (closed) and a successful Safe Stop Reset is performed, the
SS_Out output is turned ON.
If the Safe Stop is initiated or if a Safe Stop is initiated due to a fault, the SS_Out
output is turned OFF.
If an error is detected on either channel of the dual-channel output, a fault occurs,
which initiates the Category 0 Stop. The fault is latched until the drive is
successfully reset.
For more information on faults, refer to Chapter
5.
