Power Monitoring (A67-A68)

The drive may require Power Quality Meters (PQMs). The control provides PQMs as a built-in
functionality.
The drive determines and displays information about the drive input and output, as the control
processes the input waveforms and continuously samples the drive output.
For details on displaying this information, see Chapter Parameter Assignment/Addressing,
Section Options for Meter Menu (8). For a complete listing of the display parameters, refer to
Table Pick list variables for the front display in the same section.
Note
Software Model Estimate
This software model does not measure the motor temperature directly; but only estimates it
from available data. The estimate is no better than the available data, and no better than the
accuracy of the parameters entered. In particular, the software model has no data about the
ambient temperature at the location of the motor. For critical applications, a direct
measurement method such as RTDs inside the motor should be used.
