Lost Cmd Time
This parameter is used to set the time the inverter takes to decide that the command is lost. When the remote
command via network is lost for the lost command decision time (PRT-13 Lost Cmd Time + the time set at
nciRdvHrtBt), 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.’ If the network
command is recovered before the lost command decision time (PRT-13 Lost Cmd Time + the time set at nciRdvHrtBt)
is passed, the inverter does not output a fault trip and continues normal operation.
Caution
Lost command time protection operates only when the ‘nciRcvHrtBt’ variable is set to any value other than ‘0.’
