Drive Recorder - Mitsubishi Electric MELSERVO-J5 MR-J5 Series User Manual

Drive recorder

This function continuously monitors the servo amplifier status and records the state transition before and after an alarm for a
fixed period of time.
By using MR Configurator2 via a network or USB connection, the data recorded inside the servo amplifier can be read in order
to analyze alarms.
An engineering tool (such as GX LogViewer and MR Configurator2) can be used to display monitor and waveform data, and
reference to servo parameter data and output files in the drive recorder.
• When using MR Configurator2
Alarm occurrence data is automatically recorded.

• The drive recorder does not operate in the following cases.
When using the graph function with an engineering tool.
When using the machine analyzer function.
When [Pr. PF21 Drive recorder switching time setting] is set to "-1" (Drive recorder function disabled).
• For the alarm (common alarm) which applies to all axes of a multi-axis servo amplifier, the drive recorder
data is saved on individual axes. For the alarm (axis-specific alarm) which applies to a specific axis of a
multi-axis servo amplifier, the drive recorder data is only saved on the axis at which the alarm occurred, and
the drive recorder data of other axes is not saved.
• To read recorded data from the drive recorder by using the FTP server function, use a network supporting
the function.
• When the drive recorder data (JSON) files on the server are listed by using the FTP server function, the file
size will appear as 0 bytes.
• Even if the trigger is satisfied while the save processing on the servo amplifier side is not completed, the
drive recorder data of other axes are not saved.
