Drive Recorder - Mitsubishi Electric 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.
By using an engineering tool (such as MR Configurator2), the record data of the drive recorder can display the monitor and
waveform data, and the servo parameter data can be referenced.
Alarm occurrence data is automatically recorded.
Alarm occurrence
Servo amplifier
• 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).
• If an alarm occurs on all the axes of a multi-axis servo amplifier, the drive recorder data is saved on each
axis. If an alarm occurs on any of the axes, the drive recorder data is saved on the subject axis of the alarm
occurrence, and the drive recorder data of other axes is not saved.
Precautions
• When using the graph function with an engineering tool, the drive recorder function cannot be used. To use the drive
recorder function, wait until the time set in [Pr. PF21 Drive recorder switching time setting] passes, cycle the power of the
servo amplifier, or perform the software reset after using the graph function.
• If the sampling cycle of an analog trigger or digital trigger is long, the establishment of the trigger may not be able to be
detected. In that case, shorten the sampling cycle.
• If the power supply of the servo amplifier is turned off during data storage of the drive recorder (immediately after alarm
occurrence), data at alarm occurrence may not be recorded normally.
• The storage area of the servo amplifier has a life. When using the manual setting mode with the drive recorder, be sure to
consider the number of writings.
