Description
contactor fault
E46-Asymmetry
I-AC
Inverter evaluated high asymmetry of AC currents. This fault can be configured in [860]
(page 76). This For the duration of the fault, the value of I-AC asymmetry [868] (page 19)
is displayed in FAULTS window.
E47-Efficiency
decrease
Inverter evaluated decrease of efficiency. This might be caused by malfunction of the
inverter or incorrect parameter configuration. This fault can be enabled or disabled in
[864] (page 36). For the duration of the fault, the value of Inv. efficiency [859] (page 15)
is displayed in FAULTS window.
E48-DC leakage
Inverter evaluated high leakage currents from DC inputs when the AC contactor was off.
This might be caused by malfunction of the inverter or current sensing module. For the
duration of the fault, the value of Sum DC currents [634] (page 15) is displayed in
FAULTS window.
E49-IGBT
Module
overheating
IGBT is operated at very low voltage Vdc, high frequency of PWM switching or at currents
that are not approved by the manufacturer IGBT module. The value of the maximum IGBT
current is displayed in FAULTS window.
E50-Reserved
reserved
E51-Reserved
reserved
E52-End of the
trial period
The trial period has expired. The operation is locked, please contact the supplier of
inverter or device in which the inverter is used, and ask for the conditions for termination
of trial operation.
E53-High
grid
impedance
High grid impedance Grid impedance [1141] (page 21), which exceeded the threshold set
by Grid imp. threshold [1140] (page 74).
