Diagnostics

Fault and warning messages, data logging
See chapter
Fault tracing
(page
327
).
 Signal supervision
Six signals can be selected to be supervised by this function. Whenever a
supervised signal exceeds or falls below predefined limits, a bit in
32.01
Supervision status is activated, and a warning or fault generated.
The supervised signal is low-pass filtered.

 Energy saving calculators
This feature consists of the following functionalities:
• An energy optimizer that adjusts the motor flux in such a way that the total
system efficiency is maximized
• A counter that monitors used and saved energy by the motor and displays
them in kWh, currency or volume of CO
2
emissions, and
• A load analyzer showing the load profile of the drive (see section Load
analyzer
on page
81
).
In addition, there are counters that show energy consumption in kWh of the
current and previous hour as well as the current and previous day.
Note: The accuracy of the energy savings calculation is directly dependent on
the accuracy of the reference motor power given in parameter 45.19
Comparison power
.
Settings and diagnostics
