5Functions set with parameters
(1) Setting the calibration
Set the Base coordinate system
robots, in parameter: RBCORD with the X, Y, Z, A, B and C coordinate values.
Note) When using a locomotion axis, set the positional relation for when the locomotion axis coordinate
value is "0".

(2) Checking the calibration setting results
Check that each robot has been correctly calibrated with the following steps.
1) Looking at the system layout drawing, etc., set one reference point for each robot.
inafter, reference point)
2) Move the tip of the robot hand to the set reference point using jog operations.
3) Check the robot (system) status variable:

4) Compare the above
Only the XYZ values are compared. If the values match, the robot has been correctly calibrated. If the
values do not match, correct the parameter:
5) Carry out the above steps for all robots which are using the interference avoidance function.

Details explanation
The robot's Base coordinate system
from the common coordinates between robots.
(Designate with X, Y, Z, A, B and C coordinate values)
1st element: X-axis coordinate value (mm)
2nd element: Y-axis coordinate value (mm)
3rd element: Z-axis coordinate value (mm)
4th element: A-axis coordinate value (deg)
(Rotation angle around X axis)
5th element: B-axis coordinate value (deg) (Rotation
angle around Y axis)
6th element: C-axis coordinate value (deg) (Rotation
angle around Z axis)
Note 1) For the A, B and C-axis coordinate values
(rotation angles), set the values obtained by
rotating in the order of around Z axis → around
Y axis → around X axis.
