E6581373

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.
