Siemens SINAMICS S210 Operating Instructions Manual page 473

Cause: Error when parameterizing the brake test.
In this configuration, the brake test cannot be started or cannot be started without error.
Alarm value (r2124, interpret decimal):
1:
No motion monitoring functions have been enabled.
4:
No brake was configured (p10202).
8:
The brake test is configured for an internal brake, however the safety brake control is not enabled (p9602).
16:
The safe brake test and safety without encoder are simultaneously enabled (p9506). This is not permissible.
Note:
SBT: Safe Brake Test
Remedy: Check parameterization of the brake test.
A01788 SI: Automatic test stop waits for STO deselection via motion monitoring functions
Reaction: NONE
Acknowledge: NONE
Cause: The automatic test stop (forced checking procedure) was not able to be carried out after powering up.
Possible causes:
- the STO function is selected via safe motion monitoring functions.
- a safety message is present, that resulted in a STO.
Note:
STO: Safe Torque Off
Remedy: - deselect STO via safe motion monitoring functions.
- remove the cause of the safety messages and acknowledge the messages.
Note:
The automatic test stop is performed after removing the cause.
A01796 SI P1: Wait for communication
Reaction: NONE
Acknowledge: NONE
Cause: The drive waits for communication to be established to execute the safety-relevant motion monitoring functions.
Note:
STO is active in this state.
Alarm value (r2124, interpret decimal):
3: Wait for communication to be established to PROFIsafe F-Host.
Remedy: If the message is not automatically withdrawn after a longer period of time, then carry out the following checks:
- 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.
Note:
STO: Safe Torque Off

A01798 SI Motion P1: Test stop for motion monitoring functions running
Reaction: NONE
Acknowledge: NONE
Cause: The forced checking procedure (test stop) for the safe motion monitoring functions is currently in progress.
