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 0 = Off
Range: 1 = On
Proprieties: CFG
Access groups 01 PARAMETER GROUPS
via HMI:
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 0 = Off
Range: 1 = On
Proprieties: CFG
Access groups 01 PARAMETER GROUPS
via HMI:
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.
P0348 – Motor overload Protection
Adjustable 0 = Off
Range: 1 = Fault/Alarm
2 = Fault
3 = Alarm
