F30625 SI P2: Sign-of-life error in safety data
Explanation The "Safety Integrated" function integrated in the drive on monitoring channel 2 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.
● The enable signal for the safety functions in both monitoring channels is inconsistent (p9601 = 0, p9801
<> 0).
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.
● Check the enabling of the safety functions for both monitoring channels and correct if necessary (p9601,
p9801).

ment
Explanation The "Safety Integrated" function integrated in the drive on the Motor Module (MM) has detected a brake
control fault and initiated a STOP A.
The motor cable shield is not correctly connected.
Defect in the brake control circuit of the Motor Module.
Fault value (r0949, interpret decimal):
● 10: Fault for "Open brake", parameter p1278 incorrectly set
Brake not connected or interrupted cable (check whether for p1278 = 1 and p9602/p9802 = 0 (SBC
deactivated) the brake opens).
Ground fault, brake cable
