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.
MR Configurator2 with software version 1.110Q or later supports saving data in GX LogViewer format (JSON file) with the
graph function or drive recorder function.
