6-1 Communications Line Errors

Malfunctions in CompoBus/D communications that are a result of broken wires, short circuits, reversed wiring, duplicate node address assignments, or noise interference are detected as transmission (BUS) errors. When a transmission error is detected, the Inverter’s Fault Bit will turn ON and the motor will coast to a stop. (For Inverters with a software version of 1042 or later, the operation when a communica- tions error occurs can be set using constant F9-06.)

When an error is detected, perform error processing according to the indicator display of the Compo- Bus/D Communications Card.

HOperation Indicators
