Allen-Bradley Kinetix 5100 2198-E1004-ERS - SS Signal Status;Behavior for STO Faults

Figure 193 - Typical Fault Reset Sequence
For Safety Status (SS), you can configure one parameter/attribute, ID252
(P2.093) STOFeedbackConfiguration and determine whether SS will latch, if an
STO fault occurs. If SS signal is latched when STO fault occurs, the status of SS
signal remains even when the fault has been cleared.

Fault Reset Command
IMPORTANT The STO fault (E 500) can be reset only if both inputs are in the ON state. After
the fault reset requirement is satisfied, a Fault Reset command in the
application software or DI.ARST (physical input) must be issued to reset the
E 500 fault. You can reset faults E 501, E 502, and E 503 with power cycle.
Servo Drive Status SS Signal Status
(1)
(1) Open indicates continuity between SS+ and SS– is open circuit. Close indicates continuity between SS+ and SS– is short circuit.
