Friction Failure Prediction Function - Mitsubishi Electric MELSERVO-J5 MR-J5 Series User Manual

Friction failure prediction function

The friction failure prediction function predicts device failure based on the dynamic friction (at rated speed) estimated by the
friction vibration estimation function.
• In the torque mode, the friction failure prediction function cannot be used.
Precautions [G] [WG]
• To create a dynamic friction threshold with the automatic threshold setting in the friction failure prediction function, the
equipment must be operated for 3 consecutive hours or more, and operated in the position or velocity mode for a
cumulative time of 90 hours or more after the machine total travel distance exceeds 1/2 of [Pr. PF41 Failure prediction -
Servo motor total travel distance].
• The threshold value when using the friction failure prediction function and the vibration failure prediction function can be
checked with MR Configurator2 or controller.
Precautions [A]
• To create a dynamic friction threshold with the automatic threshold setting in the friction failure prediction function, the
equipment must be operated for 3 consecutive hours or more, and operated in the position or velocity mode for a
cumulative time of 90 hours or more after the machine total travel distance exceeds 1/2 of [Pr. PF53 Failure prediction -
Servo motor total travel distance].
• The threshold value when using the friction failure prediction function and the vibration failure prediction function can be
checked with MR Configurator2.
