4 Faults and alarms
4.2 List of faults and alarms
Remedy: For fault value = 1:
- set the Safety Integrated password (p9761).
For fault value = 2:
- inhibit Safety Integrated (p9501, p9601) or reset safety parameters (p0970 = 5), then reset the drive parameters
again.
For fault value = 3:
- end the simulation mode for the digital input (p0795).
For fault value = 10, 14, 15, 18:
- check whether there are faults in the safety function alignment (F01655, F30655) and if required, carry out
diagnostics for the faults involved.
- use a Control Unit that supports the required function.
For fault value = 20:
- correct the enable setting (p9601).
For fault value = 21:
- use a Power Module that supports the Safety Integrated functions.
For fault value = 26:
- deactivate the simulation mode for the set signal source for STO (p9620) (p0795).
- deactivate the simulation mode (p0795) for the F-DIs used by the Safety Integrated functions (r10049, p10006,
p10009).
- For the set test stop of the F-DO with feedback signal input (p10046, p10047), check the simulation mode, and if
required, deactivate (p0795).
For fault value = 28: use the power unit with the feature "STO via terminals at the Power Module".
Note:
F-DI: Fail-safe Digital Input
STO: Safe Torque Off

F01660 SI P1 (CU): Safety-related functions not supported
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The Power Module does not support the safety-related functions. Safety Integrated cannot be commissioned.
Note:
This fault does not result in a safety stop response.
Remedy: - use a Power Module that supports the safety-related functions.
F01661 SI P1 (CU): Simulation of the safety inputs active
Message class: General drive fault (19)
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The simulation of the digital inputs of the Control Unit (p0795) is active.
It is not permissible that safety inputs are simulated.
Fault value (r0949, interpret binary):
The displayed bits indicate which digital inputs must not be simulated.
Remedy: - deactivate the simulation of the digital inputs of the Control Unit for the safety inputs (p0795).
- acknowledge fault.
F01662 Error internal communications
Message class: Hardware/software error (1)
Reaction: OFF2
Acknowledge: POWER ON
Cause: A module-internal communication error has occurred.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
