Faults and Alarms
NOTE!
The faults F051, F078, F156, F301, F304, F307, F310, F313, F316, F319, F322, F325, F328,
F331, F334, F337, F340 and F343 allow a conditional Reset, i.e., the Reset will only occur if the
temperature gets back to the normal operation range.
If after Auto-Reset, the same fault is repeated three times consecutively, the Auto-Reset function will be disabled. A fault
is considered consecutive if it happens again within 30 seconds after the Auto-Reset.
Therefore, if a fault occurs four consecutive times, the inverter will remain disabled (general disable) and the fault will
remain being indicated.
If P0340
≤
2, auto-reset will not occur.
P0342 – Motor Unbalanced Current Detection
Adjustable
Range:
0 = Off
1 = On
Factory
Setting:
0
Properties:
CFG
Access groups
via HMI:
01 PARAMETER GROUPS
45 Protections
Description:
This parameter enables the motor unbalanced current detection, which will be responsible for the F076 fault
actuation.
This function will be enabled to actuate when the conditions below were fulfilled simultaneously for longer than 2
seconds.
1. P0342 = On.
2. Enabled inverter.
3. Speed reference higher than 3 %.
4. |Iu - Iv| or |Iu - Iw| or |Iv - Iw| > 0.125 x P0401.
P0343 – Ground Fault Detection
Adjustable
Range:
0 = Off
1 = On
Factory
Setting:
1
Properties:
CFG
Access groups
via HMI:
01 PARAMETER GROUPS
45 Protections
Description:
This parameter enables the Ground Fault Detection, which will be responsible for the F074 (Ground Fault) actuation.
Thus if wished, it is possible to inhibit the Ground Fault (F074) occurrence by setting P0343 = Off.
