5.4.3 Function overview
This section overviews the functions of FRENIC-VG Loader.

For details, refer to the FRENIC-VG Loader Instruction Manual.
5.4.3.1 Configuring function codes
FRENIC-VG Loader allows you to edit, set, and check (comparison between data saved in the
inverter and that in the connected computer) the function codes of the FRENIC-VG or
FRENIC5000VG7. Function code numbers, names, setting values, setting ranges, factory defaults,
etc. are listed on the screen.
It is also possible to save those data in CSV format so that it can be pasted to Microsoft Excel sheet
for convenience in data management.

5.4.3.2 Trace functions
The trace functions allow you to monitor the inverter running status in sequential waveforms.
The following three types of trace functions are available. Make use of each type according to its
feature. The trace data can be saved in a computer so that it is possible to analyze failures not only at
the site but also at offices.
1 Traceback: If the inverter causes an alarm, it automatically saves the running states in
waveforms into its memory. FRENIC-VG Loader reads out the waveform data
and displays it in graph form.
This function is suitable for failure analysis.
The inverter stores waveform data of the latest alarm and the last three alarms.
It discards waveform data of the older alarms.
2 Real-time trace: This function reads out the current waveform data from the running inverte
r
and shows it in graph form in real-time.
This is suitable for long-duration monitoring.
3 Historical trace: According to the preset arbitrary triggers, this function reads out the wavefor
m
data of the inverter running states held in the inverter memory and displays i
t
in graph form.
This is suitable for monitoring short-duration samples.
