Description
Def.
I-AC
asymmetry test
[861]
Turning on/off the check of output currents asymmetry and unbalance I-AC
asymmetry [868] (page 19).
warning
turned off
AC current asymmetry is not evaluated.
warning
AC currents asymmetry is evaluated. If current asymmetry of Curr. IGBT L1 [856] (page 19)
to Curr. IGBT L3 [858] (page 19) exceeds the threshold set by Max. asymmetry I-AC [862]
(page 77) for the time longer than set by Filter of I-AC asymmetry [863] (page 77), inverter
displays warning W24-Current unbalance (page 30).
fault
AC currents asymmetry is evaluated. If current asymmetry of Curr. IGBT L1 [856] (page 19)
to Curr. IGBT L3 [858] (page 19) exceeds the threshold set by Max. asymmetry I-AC [862]
(page 77) for the time longer than set by Filter of I-AC asymmetry [863] (page 77), inverter
generates the fault E46-Asymmetry I-AC (page 34).
Max.

I-
AC [862]
Threshold value of output AC currents asymmetry.

A
÷
3000.00 A
This value represents maximum permissible difference between any phase RMS values of
the output currents.
Filter of I-AC
asymmetry
[863]
Time, during which the conditions for E45-AC contactor fault (page 33) fault
generation have to be met.
30.0 s
0.0 s ÷ 3000.0 s It serves to filter short-term transients.
7.7.5 FAULT ACKNOWLEDGEMENT

Fault is acknowledged automatically.
■ BIN
Fault is acknowledged by activating the selected binary input.
■ MODBUS
Fault is acknowledged over the MODBUS communication interface.
■ PROFIBUS
Fault is acknowledged over the PROFIBUS communication interface.
■ Special
Fault is acknowledged over the special settings [266] (page 77).

Time after fault [442]
When the fault cause no longer exists (for example
overcurrent), the fault duration time will be prolonged
by the defined time.

SPECIAL SETTING
Group of parameters number [266]
Setting the special source of fault confirmation, e.g. in the chosen time of day or over the analog input.
