 Tracing procedure
1.
Preparing a USB memory device
Select a USB memory device with ample capacity to store the necessary amount of trace data. When the trace
function is used in the recorder mode, use a USB memory device with at least 1 GB of free space.
2.
Prior setting for tracing
Set Pr.1021 to select a trace mode.
Set Pr.1022 Sampling cycle and Pr.1023 Number of analog channels according to the necessary sampling time.
Use Pr.1027 to Pr.1034 to set analog sources, and Pr.1038 to Pr.1045 to set digital sources.
Set a trigger type in Pr.1025.
3.
Tracing
Set Pr.1020 or Pr.1024 to start sampling or store trace data in the USB memory device.
The trace status can be monitored. (Refer to
4.
Waveform check
By using FR Configurator2, trace data stored in a USB memory device can be displayed on a computer screen. For
details, refer to the FR Configurator2 Instruction Manual.
 Selection of trace mode (Pr.1021)
• Select how to save the trace data which results from sampling the inverter status.
• There are two trace data save methods, memory mode and recorder mode.

NOTE
• When the trace function is used in the recorder mode, use USB memory device having at least 1 GB of free space.
• Data transferred to USB is saved in the "TRC" folder under the "FR_INV" folder.
• Up to 99 sets of trace data can be stored in the USB memory device in the memory mode. When a data set is transferred to
the USB memory that contains 99 sets of data, its "MEM001.tr1" file will be overwritten. REC001.tr1 is the only data file stored
in the recorder mode.
• The data sampled in the recorder mode will be corrupted by resetting or turning OFF the inverter during sampling.
• By using FR Configurator2, the trace data of the internal RAM can be directly transmitted to the personal computer via the
USB cable. For details, refer to the Instruction Manual of FR Configurator2.

Description
Trace data is stored sequentially to the internal RAM
in the inverter.
Trace data is stored sequentially to the internal RAM
in the inverter, and automatically transferred to the
USB memory device.
Trace data is stored directly on the USB memory
device. Sampling data is fixed at 8 analog channels
and 8 digital channels. The sampling cycle in this
mode is longer than in the memory mode. (1 ms or
longer)

To store trace data on a USB memory device, set
Pr.1020 Trace operation selection = "4" after the
sampling and tracing is completed.
Trace data is automatically stored on the USB
memory device after tracing is completed.
To stop sampling and complete storing trace data
after the sampling is started, set "2" (forced trigger) or
"3" (sampling stop) in Pr.1020 Trace operation
selection.
