7.4. Communication health management
This option unit has communication health management function.
1. Communication time out function (nciRcvHrtBt)
This value manages the communication time out function. This option unit would initialize the drive
command/setpoint variables and try to stop the motor in case of not receiving an update of the
following variables within the specified Receive Heartbeat time (nciRcvHrtBt).
- nviDrvSpeedStpt
- nviDrvSpeedScale
- nviInvOutFreq
In this case, the inverter output behavior can be determined by the parameter
f851. However, next
selections are invalid.
- None (continued operation)
2. Node health transmission function (nciSndHrtBt, nciMinOutTm)
This option unit informs the network manager to its own health. Network variables controlled by this
function are shown in the table below.
