Fieldbus Status Word for Unidrive
The status word is an efficient way of remotely monitoring and
diagnosing the status of the Unidrive. Each bit in the status word
indicates the status of a function of the Unidrive, e.g. At Speed, Drive
Healthy, etc. The status word is addressed in the UD70 by reading
from #90.11.

Disabling Cyclic Data Channels
Set the appropriate channel mapping parameter to -1, and reset the
Unidrive DeviceNet Interface.
If an application only requires 2 cyclic data channels, the remaining
channel can be disabled. This means that the data received from that
channel will not be written to any Unidrive parameter. It does not
actually remove the channel from the DeviceNet network.
