Graph (monitor area)

Data such as output frequency and current of the inverter can be sampled, and the results can be
displayed in a waveform graph. The sampled data can be saved in a file (the *.jpg, *.emf, *.gp4, or
*.csv file) to be read and displayed (import the *.gp4 or *.st1 file).
To display the "Graph" window, select [graph (G)] in the [monitor (M)] menu, or select
toolbar.
There are two sampling methods.
• High speed sampling
The data can be collected at a shortest interval of 0.125 [ms]. Only one station can be set as the
sampling target. The high speed sampling is available only when the USB is connected.
• Monitor sampling
The sampling interval changes according to the communication settings (communication speed or
communication port) or the number of sampling items.

Running other applications during high speed sampling, or performing personal computer file
operations during high speed sampling, etc., will cause communication errors (error code
0x80020007 or 0x80020008) or buffer overflow errors to occur, and data will not be able to
be displayed correctly. In this case, take countermeasures such as closing other
applications, refraining from FR Configurator2 operations, or setting a larger value for the
mask counter of the sampling interval.

High speed sampling: From 0.125 [ms] (mask count: 1) to 20 [ms] (mask count: 30) can be set.
Monitor sampling: From 50 [ms] to 60000 [ms] can be set (depending on the communication
speed, communication port, or the number of sampling items).
High speed sampling: Maximum (Mask count +1) × 4000
Monitor sampling: Maximum Sampling interval × 4000
Analog data of 4 channels can be sampled.
Digital data of 4 channels can be sampled.
