■
Reading recorded data via a network
When reading the recorded data from the drive recorder via a network, use the engineering tool or the FTP server function.
The read data can be checked with GX LogViewer.
The data is saved in a file as shown below.
■
Read recorded data via a USB connection
When connecting the servo amplifier and the personal computer via a USB connection, read the drive recorder data using an
engineering tool (MR Configurator2).
Recorded data deletion method
Drive recorder record data saved inside the servo amplifier are saved up to a maximum of 16 history entries. When 16 history
entries are exceeded, the oldest recorded data will be overwritten. To delete the drive recorder data recorded inside the servo
amplifier, use [Pr. PF98.0 Drive recorder - Clear history selection] or [Clear drive recorder history (Obj. 2C03h)]. Drive
recorder record data can also be deleted by clicking the history clear button on the drive recorder screen of the engineering
tool (MR Configurator2).
Saving the drive recorder data in manual setting mode
Precautions
• The storage area of the servo amplifier has a limit for the number of writings. When using the drive recorder with [Pr.
PF81.0] set to "2" (continuous sampling), consider the number of write times.
■
Record with desired data and triggers
1.
Set [Pr. PF80.0 Drive recorder - Operation mode selection] to "1" (manual setting mode).
2.
Set the sampling cycle, trigger condition, and other areas with servo parameters.
3.
Set [Pr. PF81.0 Drive recorder - Sampling start selection] to "1" (start a single sampling) or "2" (continuous sampling
start). Sampling starts.
■
Reconfiguring parameters
Servo parameters that set the sampling cycle, trigger condition, and other areas cannot be changed during sampling. Use the
following procedure to change these parameters.
1.
Set [Pr. PF81.0] to "0" (stop sampling) and stop sampling.
2.
Set the sampling cycle, trigger condition, and other areas with servo parameters.
3.
Set [Pr. PF81.0] to "1" or "2". Sampling starts.
■
Return to automatic setting mode
To save in the automatic setting mode, set [Pr. PF80.0] to "0" (automatic setting). The automatic setting mode operates
automatically.

Remark
/drvrec/dr*_nnnn.json
"*" represents the axis number (1 or higher value), and "nnnn" represents a serial number of the drive
recorder data. When data is recorded in the drive recorder, the number will increase. If the number exceeds
9999, it will return to 0 and increase again. The number corresponds with the value of Drive recorder history
index in the object dictionary.
The file size varies depending on the log data.
