Configuring the Network

NCI: nciMinOutTm

Format: SNVT_time_sec

Explanation: This Network Configuration Input sets the minimum
period of time that expires before the Network Variable Outputs can be
re-sent. All variables are updated if they changed at each period end.
This is good for limiting use of bandwidth on the LonWorks network.
Setting nciMinOutTm to 0.0 seconds disables transmission limiting.

Valid Range: 0.0 - 6553.4 seconds
Default Value: 0.0 seconds (disabled)

NCI: nciNmlSpeed

Format: SNVT_rpm

Explanation: This Network Configuration Input sets the nominal speed
of the drive in RPMs. Nominal speed uses the drive’s motor pole
parameter A199 - [Motor NP Poles] value and sets the nominal
frequency of the drive output.

Scaling: Nominal Frequency = (nciNmlSpeed * No. of Poles) ÷ 120.0
Default Value:

NCI: nciNmlFreq

Format: SNVT_freq_hz

Explanation: This Network Configuration Input sets the nominal
frequency of the drive output in Hz. This also affects commanded drive
speed. For more information, see

Drive Speed Setpoint on page 4-6

and

Speed Setpoint Scaling on page 4-6

.

Valid Range: 10.0 - 400.0 Hz
Default Value: 60.0 Hz
