Input Fault
Safe torque-off function input
discrepancy. System does not
allow motion.
Safe torque-off input discrep-
ancy is detected when safety
inputs are in a different state for
more than 1.0 second.
• Verify safety wiring and connections:
• Wire terminations at STO connector.
• Cable/header not seated correctly.
• +24V power within specified limits.
• Check state of safety inputs.
• Reset error and run proof test.
• If error persists, remove the inverter
from service immediately and return to
Rockwell Automation.
