Configuring the Network

Variable: nvoDrvCurnt

Format: SNVT_amp

Explanation: This Network Variable Output provides the drive output
current in Amps.

PowerFlex 40/400 Drive Parameter Equivalent: Parameter d003 -
[Output Current]

Variable: nvoDrvSpeed

Format: SNVT_level_percent

Explanation: This Network Variable Output provides the speed of the
drive as a percentage of the nominal speed. This Network Variable
Output is also used as a heartbeat to monitor the health of the LonWorks
communication interface.

Scaling: nciNmlFreq ÷ (nvoFreqAct * run_dir) = nvoDrvSpeed

The run_dir value is bit 3 of the drive Logic Status word. If rotation
direction is forward, then run_dir will be a positive value. If reverse, then
run_dir will be a negative value.

PowerFlex 40/400 Drive Parameter Equivalent: Parameter d001 -
[Output Freq], but scaled in percent.

Variable: nvoDrvPwr

Format: SNVT_power_kilo

Explanation: This Network Variable Output provides the drive output
power in kilowatts.

PowerFlex 40/400 Drive Parameter Equivalent: Parameter d022 -
[Output Power]
