F01625 SI P1 (CU): Sign-of-life error in the safety data
Explanation The "Safety Integrated" function integrated in the drive on the Control Unit (CU) has detected an error in the
sign-of-life of the safety data between the two monitoring channels and initiated a STOP A.
There is either a DRIVE-CLiQ communications error or communications have failed.
A time slice overflow of the safety software has occurred.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy Select Safe Torque Off and then deselect again.
● Carry out a POWER ON (power off/on) for all components.
● Check whether there is a DRIVE-CLiQ communications error between the two monitoring channels, and
if required carry out a diagnostics routine for the faults identified.
● Deselect all drive functions that are not absolutely necessary.
● Reduce the number of drives.
● Check the electrical cabinet design and cable routing for EMC compliance.

Response OFF2
Acknowledg‐ IMMEDIATELY (POWER ON)
ment
The "Safety Integrated" function integrated in the drive on the Control Unit (CU) has detected a brake control
fault and initiated a STOP A.
Fault value (r0949, interpret decimal):
Re fault value 10, 11:
Fault for "Open brake".
Parameter p1278 incorrectly set.
Brake not connected or interrupted cable (check whether for p1278 = 1 and p9602/p9802 = 0 (SBC switched-
out) the brake opens).
For fault value 20:
