Lost Preset F
This parameter is used to select an operation mode to be used when the command is lost. When remote command
via network is lost for the ‘lost command decision time’, the inverter decides that the command is lost.
This feature is available only when DRV-06 is set to ‘4.Fieldbus,’ or when DRV-07 is set to ‘7.Fieldbus.’
With this feature enabled, the selected operation mode is used when the network command is lost.
