Maintenance simulation 62
9. Maintenance simulation
This function estimates the parts replacement time or the recommended maintenance time when a
specific motion pattern (robot program) is repeated using a real machine (online) or simulations on RT
ToolBox3.
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 recommended 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
recommended 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.
Operation mode Estimation method Number of years estimated
Real machine (online) Program operation The number of years from the current
consumption degree of the robot.
Simulation 1 Cycle operation, Program operation The number of years from the brand
new robot state.
[Note] In order to use Maintenance Simulation in the simulation mode of RT ToolBox3, the function code and
parameter of the MELFA Smart Plus card need to be set.
For the setting method, refer to “3.3 Setting of maintenance simulation”.
