3.5 Tool constant settings
3.5
T
ool
constant
settings
The tool constants refer to a set of parameters including the length, angle, center of gravity, weight and
moment of inertia of the installed tool. These parameters are extremely important for ensuring precise linear
operations and appropriate acceleration/deceleration control. Before moving the robot, read carefully through
the instructions in this section and take the
steps described without fail. Tool constants for up to 32
tools can be
stored in this controllers memory. If an application involves the use of a multiple number of tools, perform the
settings for all the tools
concerned.
CAUTION
Continued use under the wrong settings for the center of gravity, weight and tools
moment of inertia may fatally damage the machine. Perform the settings set forth in this
section without fail.
The settings must be performed even for small and/or lightweight tools. The same
settings used for a large tool cannot be used for a small tool.
Table 3.5.1 Tool constants
Name
This constant is the length up to the tool tip in the TCP coordinate system (X, Y
and Z components of the tool tip). It is absolutely necessary in order to ensure
precise linear movements.
When the
tool length automatic setting function
is used, the tool length can
be ascertained automatically using the already created program.

And weight
Moment of inertia
Maximum rotation
radius
This constant is for setting the inclination of the tool tip in the TCP coordinate
system using the X, Y and Z axis rotation components. It proves useful since,
when teaching, the tool can be operated manually in the direction in which it is
pointing. When the
tool angle
simple setting function
is used, the tool angle
can be s
et easily.
This constant is for setting the tool's center of gravity position in the TCP
coordinate system and its weight. It is required in order to ensure appropriate
acceleration/de
celeration
control.
The constant is set using the
tool center of gravity (COG) and weight
automatic setting
func
tion
. (The weight of a tool cannot be input manually.)

tool name may consist

This constant is for setting the moment of inertia around the center of gravity in
the TCP
coordinate system using the X, Y and Z components. It must be set if the
moment of inertia has exceeded the allowable value.
When the
tool moment of inertia simple setting function
is used, the
moment of inertia can be set easily by designating the tool shape.
This constant is the max. radius of the tool. It is used to check the territory, etc.
