PARAMETERS
 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.

For the details of Pr.1020 , refer to page 539 .
NOTE
• When the trace function is used in the recorder mode, use a 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.
 Selection of sampling time (Pr.1022, Pr.1023)
• The sampling time is determined by the sampling cycle and the number of data acquisition points. The number of data
acquisition points differs between the memory mode and the recorder mode.
Memory mode
The sampling time varies depending on the setting in
Pr.1022 Sampling cycle and Pr.1023 Number of analog channels .
Recorder mode
The sampling time varies depending on the setting in
Pr.1023 Number of analog channels .

Sampling is performed at a sampling cycle of 1 ms even if "0 or 1" is set to Pr.1022 Sampling cycle .
Pr.1021
setting
Mode Description Storing trace data
0 Memory mode
Trace data is stored sequentially to the internal RAM
in the inverter.
To store trace data on a USB memory device, set
Pr.1020 Trace operation selection = "4" after the
sampling and tracing is completed.
1
Memory mode
(automatic
transfer) Trace data is stored sequentially to the internal RAM
in the inverter, and automatically transferred to the
USB memory device.
Trace data is automatically stored on the USB
memory device after tracing is completed.
2 Recorder mode
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 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 .
