3.5 Tool constant settings
Center of gravity (COG) and weight of tool
The tool center of gravity (COG) and weight are parameters required to exercise
the appropriate acceleration/deceleration control.
center of gravity and weight.
The tool weight cannot be input manually on the tool constant setting screen. This is to avoid the danger of
seriously damaging the machine which would result if
a weight which is considerably different
weight were to have been set by mistake. At the factory, the value of the rated conveyable weight was set.
(The tool center of gravity can be input.)
Therefore, this controller can automatically calculate the correct values for the center of gravity (COG) and
weight of tool. Use this convenient function to set the center of gravity (COG) and weight of tool.

After reading the Basic O

these settings again without fail.
Setting the center of gravity (COG) and weight of tool
Operate the robot in a predetermined manner, calculate the torque generated from the current at this time,
and use the measured value as a basis to calculate the center of gravity (COG) and weight of tool. Although
one program for sampling the current must be taught,
the center of gravity (COG) and weight of tool
be set simply by playing back the program.
For this procedure, the operator must be qualified as an
