Security

To completely prevent unauthorized access to the system from external devices, the user also must take safety measures.
Mitsubishi Electric Corporation cannot be held responsible for any problems caused by unauthorized access.
Description
This function continuously monitors the servo status
and records the state transition before and after an
alarm for a fixed period of time. The recorded data
can be checked by the Waveform-Display button on
the drive recorder window of MR Configurator2
being clicked.
This function obtains the servo status in the graph.
This function diagnoses with MR Configurator2
whether the encoder communication error is caused
by the circuit malfunction of the servo amplifier or by
the malfunction of the cables/encoder.
This function enables checking of the cumulative
energization time, the number of the inrush relay on/
off times, and the number of dynamic brake usage
times. It gives an indication of the replacement time
for parts on the servo amplifier with a service life
(such as the capacitor and the relay) before they
malfunction. MR Configurator2 is required for this
function.
This function predicts failures of the equipment and
the servo motor based on the machine total travel
distance. It gives an indication of the replacement
time for the servo motor.
This function uses the data in the servo amplifier to
estimate the friction and vibrational component of
the drive system in the equipment and to recognize
an error in machine parts such as ball screws and
bearings.
This function uses MR Configurator2 to monitor the
servo amplifier model, connected servo motor,
encoder, and other information.
Description
This function saves information of the alarm that
occurred in the servo amplifier. The information is
saved in chronological order and used for occasions
such as analyzing the cause of the alarm.
