6.6.6. nvoDrvFeedback (Velocity Feedback)
Output network variable SNVT type: SNVT_switch (95)
It provides stopped / running status and low resolution output speed of the motor. - Specification
nvoDrvFeedback | Operation | ||
value | state | ||
| |||
N/A | 0 | Stop | |
0.0 to 127.5% | 1 | Drive at 0.0 to 127.5% speed. | |
value = (Drive frequency) / nciNmlFreq / nviDrvSpeedScale | |||
|
| ||
N.B.: When the speed exceeds the 127.5%, “value” is limited to 127.5%
If “nviDrvSpeedScale” was set to 0, nvoDrvFeedback.value shows 0.0%.
The value exceeded to the resolution will be rounded.
6.6.7. nvoStatusWord (Inverter Status)
Output network variable SNVT type: SNVT_state (83) It provides the inverter status.
