SINAMICS alarms
Cause: An error was detected when carrying out the test stop on the TM54F. As fault response fail-safe input terminal signals
are transferred to the motion monitoring functions.
Fault value 0xaaaabbcc hex (r0949, interpret hexadecimal):
aaaa: Specifies the DOs or F-DIs (dependent on test step cc) for which the expected state was not assumed. The
number is bit-coded (bit 0 = F-DI 0 or F-DO 0; bit 3 = F-DI 3 or F-DO 3).
bb: Describes the cause of the fault
0x01 = Internal error (error state on the opposite side).
0x02 = Fault during comparison of switching signals: FDIs or DIs
0x03 = Internal error (delay time in the new state has still not expired).
0x04 = Fault during comparison of switching signals: DiagDOs
cc: Describes the test step of the test stop in which the fault occurred
The information below is displayed in the following format:
Test stop step slave : (test actions)(test actions) | Step Master : (test actions)(test actions)

List of test stop steps:

0xAF:(DO original state)() | 0xC5:(DO original state)() | Switching step
0xC5: End of test
The following expected states are tested in the test steps when testing the FDOs:
The information below is displayed in the following format:
Test step (SL MA): Expected DiagDO mode 1 | Expected DI20..23 mode 2 | Expected DI20..23 mode 3
(0x4C 0x57): DiagDO=0V | DI=24V | DI=24V
(0x62 0x6D): DiagDO=0V | DI=0V | DI=0V
(0x78 0x83): DiagDO=0V | DI=0V | DI=24V
(0x8E 0x99): DiagDO=24V | DI=0V | DI=24V
(0xA4 0xAF): DiagDO=0V | DI=24V | DI=24V
Example:
If an error with fault causes (bb) 0x02 or 0x04 occurs in a test stop step, the test action for the fault took place in the
previous test stop step. The expected states are tested in the next step.
Master signals fault value 0001_04AF and slave signals fault value 0001_04A4.
aaaa = 1 i.e. FDO 0 affected
bb = 04h i.e. testing of DiagFDO has failed
cc = The expected states were tested in test stop step AF on the master and A4 on the slave. Expected state
DiagDO=0V is being tested in the table; in other words, the Diag DO was at 0 V instead of the expected 24 V. The
associated test action took place in the previous step (0x99 DO OFF 0xA4 DO OFF). Both DOs were switched to OFF.
Remedy: Check the wiring of the F-DIs and F-DOs and restart the test stop. The fault is withdrawn if the test stop is successfully
completed.
Fault values 0xCCCCCCCC / 0xDDDDDDDD / 0xEEEEEEEE : These fault values are triggered together with alarm
35152. If they appear, you should check all test stop parameters. You should also check whether the firmware version
of the TM54F matches the Control Unit's software version.
You also need to check P10001, P10017, P10046, and P10047.
