Drive data diagnosis
Drive recorder
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.

Graph function
This function obtains the servo status in the graph.

Failure diagnosis
Encoder communication diagnosis
function
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.

Service life
diagnosis
Servo amplifier life diagnosis
function
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.

amplifier life diagnosis
function
Motor life diagnosis 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.
A0
A0
Machine diagnosis function
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.
A0
A0
This function automatically sets the threshold used for
detecting the error of machine parts such as ball
screws and bearings. It outputs the warning when the
friction, vibrational component, and total revolution of
the servo motor are out of the set threshold. The error
in the machine parts such as ball screws and bearings
can be detected automatically.
A0
A0
This function estimates the friction of gears and
loosening of belts (decrease in the belt tension), and
detects errors in the gears and belts.

System diagnosis
System configuration information
This function uses MR Configurator2 to monitor the
servo amplifier model, connected servo motor,
encoder, and other information.

Alarm history
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.
