STO-related Fault Codes
For fault codes and descriptions, see the Knowledgebase document 1090034,
Kinetix 5100 Servo Drive Parameter Data and Fault Codes. For information on
how to clear faults, see Clear Faults
on page 431.
Figure 191
demonstrates when the safe torque-off mismatch is detected and fault
E 501 (STO_A signal loss) or E 502 (STO_B signal loss) is posted.
Figure 191 - System Operation in the Event that the Safety Enable Inputs Mismatch
When the STO self-diagnostic (STO circuit and wiring, for example) fails, fault
E 503 is posted.
Figure 192
demonstrates when both inputs in the OFF state are detected and
fault E 500 (STO enabled) is posted.

ATTENTION: The safe torque-off fault is detected upon demand of the Safe
Torque Off (STO) function. After troubleshooting the STO function or
performing maintenance that might affect the STO function, the STO function
must be executed to verify correct operation.
