Note) When the ON/OFF function is selected for DC braking (DB), using the input terminal selection parameter, you can judge
the inverter to be normal if "" disappears when opening the circuit between the terminal and CC.
Each message in the table is displayed to give a warning but does not cause the inverter to
trip.
