4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G120D
926 List Manual (LH14), 01/2016, A5E33842313
Remedy: - carry out a POWER ON (switch-off/switch-on).
- upgrade firmware to later version.
- contact Technical Support.
F30665 SI P2: System is defective
Message class: Hardware/software error (1)
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A system defect was detected before the last boot or in the actual one. The system might have been rebooted
(reset).
Fault value (r0949, interpret hexadecimal):
200000 hex, 400000 hex:
- fault in the actual booting/operation.
Additional values:
- defect before the last time that the system booted.
Remedy: - carry out a POWER ON (switch-off/switch-on).
- upgrade firmware to later version.
- contact Technical Support.
For fault value = 400000 hex:
- ensure that the Control Unit is connected to the Power Module.
A30666 (F) SI Motion P2: Steady-state (static) 1 signal at the F-DI for safe acknowledgment
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: A logical 1 signal is present at the F-DI configured in p10106 for more than 10 seconds.
If, at the F-DI no acknowledgment was performed for safe acknowledgment, then a steady-state logical and 0 signal
must be present. This avoids unintentional safety-relevant acknowledgment (or the "Internal Event Acknowledge"
signal) if a wire breaks or one of the two digital inputs bounces.
Remedy: Set the fail-safe digital input (F-DI) to a logical 0 signal (p10106).
Note:
F-DI: Failsafe Digital Input
F30680 SI Motion P2: Checksum error safety monitoring functions
Message class: Safety monitoring channel has identified an error (10)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The actual checksum calculated by processor 2 and entered in r9398 over the safety-relevant parameters does not
match the reference checksum saved in p9399 at the last machine acceptance.
Safety-relevant parameters have been changed or a fault is present.
Note:
This fault results in a STOP A that can be acknowledged.
Fault value (r0949, interpret decimal):
0: Checksum error for SI parameters for motion monitoring.
1: Checksum error for SI parameters for component assignment.
Remedy: - check the safety-relevant parameters and if required, correct.
- set the reference checksum to the actual checksum.
- execute the function "Copy RAM to ROM".
- perform a POWER ON if safety parameters requiring a POWER ON have been modified.
- carry out an acceptance test.
