For example, a read of b2-04, DC Injection Time at Stop, which reports 100 in nvoReadParamVal is actually a setting of 1.00sec, since the increment for this parameter is 0.01 seconds.# Configurable Network TrafficThis section describes the configuration properties available for customizing the driveís periodic traffic on the network.# Send Heartbeat - nciSndHrtBtThis configuration property defines the maximum period of time that expires before the current values of nvoDrvCurnt, nvoDrvSpeed,nvoDrvVolt, and nvoDrvPwr are automatically transmitted. When enabled, this functionality is intended to indicate to the network that this nodeis functioning normally. When disabled, the values of these variables are only transmitted upon change.The default value for this configuration property is 0, which is the disabled state.# Minimum Send Time - nciMinOutTmThis configuration property defines the minimum period of time between updates of output network variables. When enabled, this functionalityreduces network traffic by limiting the automatic propagation of network variables. When disabled, changes in these network variables aretransmitted on each change.The default value for this configuration property is 1 second.
