■ Operation
1.When the Inverter has a fault, bit 0 of word m (Fault Bit) will be turned ON. Until the fault is cleared,
the Fault Flag will be ON, and this will cause the Fault Read Flag to be turned ON, and the com-
mand specified in the DM Area will be sent using the CMND instruction.
2.When the Message Communications Enabled Flag is turned ON, the completion code (D03001)
will be examined. If an error is found, the error code will be stored in D00100 and the command
will be re-executed. If normally completed, the fault code will be stored in D00200 and the Mes-
sage Sent Flag will be turned ON, and the Sending Message Flag will be turned OFF.
3.When the Reset Input Bit is turned ON, bit 2 of word n (Fault Reset Input Bit) will turn ON. When
the fault is cleared, the Fault Flag will turn OFF.
