Maintenance Simulation - Mitsubishi Electric CR800-D Series User Manual

2.1.1. Maintenance simulation

Using the real machine (online) or simulations on RT ToolBox3, this function estimates the parts
replacement time or the recommended maintenance time when specific motion patterns (robot
programs) are repeated.
Maintenance simulation estimates the following items.
1) Number of years up to the time of replenishing grease
2) Number of years up to the time of timing belt replacement
3) Recommended number of years up to the maintenance time for overhauling parts
(Of reduction gear, bearing, ball screw, and ball spline, the part for which there is the shortest
number of years of maintenance)
There are two types of estimation methods, "Program operation" and "1 Cycle operation".
For the real machine (online), estimation is possible using "Program operation", and for simulation, in
addition to "Program operation", "1 Cycle operation" can also be used.
•1 Cycle operation: Specify the start line and end line of the robot program to estimate the parts
replacement/ the recommended maintenance time based on its 1 cycle operation
pattern.
Because 1 cycle can be accurately specified on a robot program, it is possible to
more accurately estimate the number of years when 1 cycle operation is repeated
than when using Program operation.
The estimation result of the number of years is from the brand new robot state.
• Program operation: While running a robot program automatically, the parts replacement/ the parts

replacement/ the recommended maintenance time is estimated based on the
operation pattern from when the start button is pressed to when the end button is
pressed.
Accurate 1 cycle (start line and end line) cannot be specified but Program
operation is used when it is difficult to specify 1 cycle on the program, such as
when the program uses external signals.
The estimation result for a real machine (online) is the number of years from the
current consumption degree of the robot.
The estimation result for simulation is the number of years from the brand new
robot state.
