1.1 Function explanation
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 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.
This function estimates the friction of gears
and loosening of belts (decrease in the belt
tension), and detects errors in the gears and
belts.
This function uses MR Configurator2 to
monitor the servo amplifier model, connected
servo motor, encoder, and other information.
