r0948[0...63] Fault time - - - - - U32 3
Time stamp to indicate when a fault has occurred.
P0969 (system run time counter) is the possible source of the time stamp.

r0949[0...63] CO: Fault value - - - - - U32 3
Displays converter fault values. It is for service purposes and indicates the type of fault reported.
The values are not documented. They are listed in the code where faults are reported.

P0952 Total number of trips 0 - 65535 0 T - - U16 3
Displays number of trips stored in r0947 (last fault code).
Dependency: Setting 0 resets fault history (changing to 0 also resets r0948 - fault time).
Note:
If the source of a non-momentary fault remains active before a factory reset, the converter removes the
source first and then places the fault into the fault history during a factory reset. That means P0952 still
has a non-zero value after the factory reset. If you want to clear the fault history, you need to perform a
second factory reset or set P0952 = 0.
r0954[0...2] CO: Freq. setpoint after
RFG at fault [Hz]
- - - - - Float 3
Displays the setpoint after RFG when the first instantaneous fault occurs (see r1170).
Index: [0] Recent trip - Fault information
[1] Recent trip - 1 Fault information
[2] Recent trip - 2 Fault information
Note: Only one set of fault information is stored per block of instantaneous faults. r0954[0] corresponds to
r0947[0...7], r0954[1] corresponds to r0947[8...15] and r0954[2] corresponds to r0947[16...23].
