Parameter Changeable Via; Co: Last Fault Code - Siemens MICROMASTER 440 Parameter Manual

Parameter Description
P0927

Parameter changeable via

CStat: CUT
P-Group: COMM
Specifies the interfaces which can be used to change parameters.
This parameter allows the user to easily protect the inverter from unauthorized modification of parameters.
Annotation: Parameter P0927 is not password protected.
Bitfields:
Bit00 PROFIBUS / CB
Bit01 BOP
Bit02 USS on BOP link
Bit03 USS on COM link
Example:
Bits 0, 1, 2 and 3 set:
The default setting allows parameters to be changed via any interface. If all bits are set, the parameter is
displayed on BOP as follows:
BOP:
P0927
Bits 0, 1, 2 and 3 reset:
This setting allows no parameters to be modified via any interface with the exception of P0003 and P0927. If
all bits are reset, the parameter is displayed on BOP as follows:
BOP:
P0927
Details:
The seven-segment display is explained in the "Introduction to MICROMASTER System Parameters" in this
handbook.
r0947[8]

CO: Last fault code

P-Group: ALARMS
Displays fault history according to the diagram below
where:
- "F1" is the first active fault (not yet acknowledged).
- "F2" is the second active fault (not yet acknowledged).
- "F1e" is the occurrence of the fault acknowledgement for F1 & F2.
This moves the value in the 2 indices down to the next pair of indices, where they are stored. Indices 0 & 1
contain the active faults. When faults are acknowledged, indices 0 & 1 are reset to 0.

Index:
r0947[0] : Recent fault trip --, fault 1
r0947[1] : Recent fault trip --, fault 2
r0947[2] : Recent fault trip -1, fault 3
r0947[3] : Recent fault trip -1, fault 4
r0947[4] : Recent fault trip -2, fault 5
r0947[5] : Recent fault trip -2, fault 6
r0947[6] : Recent fault trip -3, fault 7
r0947[7] : Recent fault trip -3, fault 8
Example:
If the inverter trips on undervoltage and then receives an external trip before the undervoltage is
acknowledged, you will obtain:
- r0947[0] = 3
- r0947[1] = 85 External trip (F0085)
Whenever a fault in index 0 is acknowledged (F1e), the fault history shifts as indicated in the diagram
above.
Dependency:
Index 1 used only if second fault occurs before first fault is acknowledged.
