4 Faults and alarms
4.2 List of faults and alarms
Remedy: - Deselect STO via the STO terminals at the Power Module (connect STO_A and STO_B to 24 V).
- if required, de-activate the "STO via terminals at the Power Module" function via the DIP switch (both DIP switches
set to "OFF").
Note:
- After the cause has been removed, the Control Unit continues to power up.
- While the alarm remains, a possibly existing brake is kept closed.
STO: Safe Torque Off
A01796 (F, N) SI P1 (CU): Wait for communication
Message class: Communication error to the higher-level control system (9)
Reaction: NONE
Acknowledge: NONE
Cause: The drive waits for communication to be established to execute the safety-relevant motion monitoring functions.
Note:
In this state, the pulses are safely suppressed.
Alarm value (r2124, interpret decimal):
3: Wait for communication to be established to PROFIsafe F-Host.
Remedy: If, after a longer period of time, the message is not automatically withdrawn, the following checks have to be made:
- check any other PROFIsafe communication messages/signals present and evaluate them.
- check the operating state of the F-Host.
- check the communication connection to the F Host.

C01798 SI Motion P1 (CU): Test stop for motion monitoring functions running
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The forced checking procedure (test stop) for the safe motion monitoring functions is currently in progress.
Remedy: Not necessary.
The message is automatically withdrawn when the test stop has been completed.
Note:
SI: Safety Integrated
C01799 SI Motion P1 (CU): Acceptance test mode active
Message class: Safety monitoring channel has identified an error (10)
Reaction: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The acceptance test mode is active.
Remedy: Not necessary.
The message is withdrawn when exiting the acceptance test mode.
A01900 (F) PROFIBUS: Configuration telegram error
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: A PROFIBUS master attempts to establish a connection using an incorrect configuring telegram.
Alarm value (r2124, interpret decimal):
2: Too many PZD data words for input or output. The number of possible PZD is specified by the number of indices in
r2050/p2051.
3: Uneven number of bytes for input or output.
211: Unknown parameterizing block.
501: PROFIsafe parameter error (e.g. F_dest).
502: PROFIsafe telegram does not match.
Additional values:
Only for internal Siemens troubleshooting.
