• Inspection notice function
• Preventive maintenance function for the hardware
8.21.2 Preventive Maintenance Function for the Speed Reducer
Diagnoses the duration of life for the speed reducer by using the both
methods of the lifetime calculation and the torque average value. The
diagnosis is executed by operating the job in the play mode. It is
unnecessary to prepare the job for this diagnosis.
8.21.2.1 Diagnose by the Lifetime Calculation
Outline
This function calculates the torque and the speed of the each axis during
the job operation, and diagnoses the time to replace the speed reducer by
the lifetime calculation. The replacement time is informed by displaying
the message and turning the replacement signal ON.
Operating the job in the play mode performs the diagnosis automatically.
Set the Replacement Signal
Set the universal output signal to notify the replacement time by following
procedures.
1. Change the security mode to the management mode.
• The accuracy of the performance of the life diagnosis is
not guaranteed. Use this function as the one of the
methods to determine the duration of life for the speed
reducer.
• If the periodic grease replenishment and grease
replacement are not performed, or the excessive
pressure is applied to the speed reducer, such as the
mechanical interference etc, it will be failed before
reaching to the diagnosis period.
• The diagnosis is performed by executing the job in the
play mode. When operating the robot in the teach mode
(operation by the axis key, FWD operation and test
operation), the life diagnosis function is not performed.
This function is only available for the robot axes. As for the
external axes, this function is not available.
