What the Fault Means

Fault: SI P2: Parameter processor 2 parameter error

Likely causes

• When accessing the Safety Integrated parameters for the processor 2 in the non-volatile memory, an error has occurred
• Note: This fault results in a STOP A that can be acknowledged
• 1136 SINAMICS G120 CU250S-2 Control Units List Manual (LH15), 01/2016, A5E33842890 4 Faults and alarms 4.2 List of faults and alarms Fault value (r0949, interpret decimal): 129: Safety parameters for processor 2 corrupted
• 131: Internal software error on processor 1

Solution and Safe First Checks

1. re-commission the safety functions.
2. replace the memory card or Control Unit.
3. activate the safety commissioning mode (p0010 = 95).
4. start the copy function for SI parameters (p9700 = D0 hex).
5. acknowledge data change (p9701 = DC hex).
6. exit the safety commissioning mode (p0010 = 0).

Safety: do not work inside the panel without isolating the power; if unsure, consult a qualified technician.
