SAFE FLT 09 - SS IN
GuardStopInputFault
Safe torque-off function mismatch.
System does not allow motion. Safe
torque-off mismatch is detected when
safety inputs are in a different state for
more than 1.0 second.
• Verify safety wiring and connections:
– Wire terminations at safe torque-off (STO) connector
– Cable/header not seated correctly
– +24V power
• Check state of safety inputs.
• Reset error and run proof test.
• If error persists, return the drive to Rockwell Automation.

SafetyCoreFault
Drive safety diagnostic detected internal
STO design failure.
• Cycle control power
• Return drive for repair if fault continues
SAFE FLT S03 - Gate Drive
GuardGateDriveFault
(1)
Drive safety diagnostic detected internal
STO design failure.
• Cycle control power
• Execute STO function
• Return drive for repair if fault continues
