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.)
