Unbalance Fault**
This fault indicates unbalance in output current of the Inverter Units. If due to
the unbalance, the output current of one or more Inverter Unit exceeds its
rated current for 60 seconds, this fault will come. The rated current of each
Inverter Unit is 600 A for 400 V Series and 387 A (415 A for 7.10C control
version and above) for 500/600 V Series. This fault applicable only for PCA-
2049A parallel interface board.

6 Temperature Fault**
This fault occurs if heat sink temperature ≥90 °C or ≤0°C for 2 seconds of
inverter unit 6. This fault applicable only for PCA-2049A parallel interface
board.
66
Motor Over Load Fault
This fault Indicates that the motor current exceeded the thermal operation
time having inverse time characteristics. Parameter B119 (motor overload
selection) will affect this fault.
67
Panel Temper
ature Fault
This fault Indicates that the panel inside temperature is > C324 (Panel
Temperature Limit). Fault will be reset if panel inside temperature is < C324
(Panel Temperature Limit) - 5 °C. This fault is applicable for IU/DU system.
** This Fault is only applicable when multiple inverter units (IU) are used.
