312 Parameters
31.120 LSU earth fault (Only visible when IGBT supply unit control activated by
95.20 )
Selects how the supply unit reacts when an earth fault or
current unbalance is detected.
Fault
No action No action taken. 0
Warning The supply unit generates an AE02 Earth leakage warning. 1
Fault The supply unit trips on fault 2E01 Earth leakage. 2
31.121 LSU supply phase
loss
(Only visible when IGBT supply unit control activated by
95.20 )
Selects how the supply unit reacts when a supply phase loss
is detected.
Fault
No action No action taken. 0
Fault The supply unit trips on fault 3E00 Input phase loss. 1
32
32 Supervision Configuration of signal supervision functions 1…3.
Three values can be chosen to be monitored; a warning or
fault is generated whenever predefined limits are exceeded.
See also section
Signal supervision (page 123 ).
32.01 Supervision status Signal supervision status word.
Indicates whether the values monitored by the signal
supervision functions are within or outside their respective
limits.
Note: This word is independent of the drive actions defined
by parameters 32.06 , 32.16 and 32.26 .
0000b
0000…0111b Signal supervision status word. 1 = 1
32.05 Supervision 1
function Selects the mode of signal supervision function 1. Determines
how the monitored signal (see parameter
32.07 ) is compared
to its lower and upper limits ( 32.09 and 32.10 respectively).
The action to be taken when the condition is fulfilled is
selected by
32.06 .
Disabled
Disabled Signal supervision 1 not in use. 0
Low Action is taken whenever the signal falls below its lower limit. 1
High Action is taken whenever the signal rises above its upper
limit. 2
Abs low Action is taken whenever the absolute value of the signal falls
below its (absolute) lower limit. 3
Abs high Action is taken whenever the absolute value of the signal
rises above its (absolute) upper limit. 4
Both Action is taken whenever the signal falls below its low limit or
rises above its high limit. 5
Abs both Action is taken whenever the absolute value of the signal falls
below its (absolute) low limit or rises above its (absolute) high
limit. 6
No. Name/Value Description Def / FbEq16
Bit Name Description
0 Supervision 1 active 1 = Signal selected by 32.07 is outside its limits.
1 Supervision 2 active 1 = Signal selected by 32.17 is outside its limits.
2 Supervision 3 active 1 = Signal selected by 32.27 is outside its limits.
