Siemens SINAMICS S210 - SI P1 (CU): Test Stop for STO Required; SI Motion P1 (CU): STOP a Initiated

Reaction upon F: Servo: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
A01699 (F) SI P1 (CU): Test stop for STO required
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The time set in p9659 for the forced checking procedure (test stop) for the "STO" function has been exceeded. A new
forced checking procedure is required.
After the next time the "STO" function is de-selected, the message is withdrawn and the monitoring time is reset.
Note:
- this message does not result in a safety stop response.
- the test must be performed within a defined, maximum time interval (p9659) in order to comply with the requirements as
laid down in the standards for timely fault detection and the conditions to calculate the failure rates of safety functions (PFH
value). Operation beyond this maximum time period is permissible if it can be ensured that the forced checking procedure
is performed before persons enter the hazardous area and who are depending on the safety functions correctly functioning.

Remedy: Select STO and then de-select again.
Note:
CU: Control Unit
SI: Safety Integrated
STO: Safe Torque Off / SH: Safe standstill
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
C01700 SI Motion P1 (CU): STOP A initiated
Message value: -
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive is stopped via a STOP A (STO via the safety switch-off signal path of the first monitoring channel).
Possible causes:
- stop request from the second monitoring channel.
- STO not active after a parameterized time (p9557) after test stop selection.
- subsequent response to the message C01706 "SI Motion CU: SAM/SBR limit exceeded".
- subsequent response to the message C01714 "SI Motion CU: Safely Limited Speed exceeded".
- subsequent response to the message C01701 "SI Motion CU: STOP B initiated".
- subsequent response to the message C01716 "SI Motion CU: tolerance for safe motion direction exceeded".
