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.

board.
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.
