Siemens 440 manual P0927 Parameter changeable via, R09478 CO Last fault code, 106

Parameter Description Issue 01/06

P0927	Parameter changeable via				Min:	0
	CStat:	CUT	Datatype: U16	Unit: -	Def:	15
	P-Group:	COMM	Active: first confirm	QuickComm.: No	Max:	15

Specifies the interfaces which can be used to change parameters.

Level

2

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	0	NO	1	YES
Bit01	BOP		0	NO	1	YES
Bit02	USS on BOP	link	0	NO	1	YES
Bit03	USS on COM	link	0	NO	1	YES

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		Min:	-
	Datatype: U16	Unit: -	Def:	-
	P-Group: ALARMS		Max:	-

Level

2

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.

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 Undervoltage (F0003)

-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.
