4.6. Output network variables

4.6.1. Output network variable update

Normally, output network variables are updated when the inverter status was changed. Automatic
transmission function is also prepared by "nciSndHrtBt (Send Heartbeat Time)", "nciMinOutTm
(Minimum Send Time)" configuration properties.
See section 5.4 "Communication health management" for detail.

4.6.2. nvoDrvSpeed (Drive Speed Feedback)

SNVT type: SNVT_lev_percent (81)
It provides the motor speed as a percentage of the nominal speed. Negative value means a speed in
reverse.
- Valid range: -163.840 to 163.830%
- Unit: 0.005% (The resolution depends on the inverter specification)
N.B.: It indicates the rotating direction at the time of a stop, only when at the time of the operation starts
after changing rotating direction. However, the rotating direction of the inverter performs correctly.

4.6.3. nvoDrvCurnt (Drive Output Current)

SNVT type: SNVT_amp (1)
It provides the inverter output current in amperes.
- Valid range: 0.0 to 3276.6 A (It is overwritten 0.0A when the inverter faulted).
- Unit: 0.1 A

4.6.4. nvoDrvVolt (Drive Output Voltage)

SNVT type: SNVT_volt (44)
It provides the inverter output voltage in volt.
- Valid range: 0.0 to 3276.6 V (It is overwritten 0.0V when the inverter faulted).
- Unit: 0.1 V

4.6.5. nvoDrvPwr (Drive Output Power)

SNVT type: SNVT_power_kilo (28)
It provides the inverter output power in kilo-Watt.
- Valid range: 0.0 to 6553.5 kW (It is overwritten 0.0kW when the inverter faulted).
- Unit: 0.1 kW

4.6.6. nvoDrvRunHours (Drive Total Running Hours)

SNVT type: SNVT_time_hour (124)
This output network variable provides the total operation time for the motor in running hours.
- Valid range: 0 to 65534 h (The overflow caused the value to return 0).
- Unit: 1 h
