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.

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:

"b - - n n" (bits 0, 1, 2 and 3 set) in the default setting means that parameters can be changed via any

interface.

"b - - r n" (bits 0, 1 and 3 set) would specify that parameters can be changed via PROFIBUS/CB, BOP and

USS on COM link (RS485 USS) but not via USS on BOP link (RS232).

Details:

The seven-segment display is explained in the "Introduction to MICROMASTER System Parameters" in this

handbook.

r0947[8] Last fault code Min: -

Datatype: U16 Unit: - Def: -

P-Group: ALARMS Max: -

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 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.
