8.1.1 Home Position Calibration
Home position calibration is an operation in which the home position and
absolute encoder position coincide. Although this operation is performed
prior to shipment at the factory, the following cases require this operation
to be performed again.
• Change in the combination of the manipulator and DX100
• Replacement of the motor or absolute encoder
• Clearing stored memory (by replacement of NIF01 circuit board,
weak battery, etc.)
• Home position deviation caused by hitting the manipulator against a
workpiece, etc.
To calibrate the home position, use the axis keys to calibrate the home
position mark on each axis so that the manipulator can take its posture for
the home position. There are two operations for home position calibration:
• All the axes can be moved at the same time: Recalibrate the home
position by moving all the axes
together if changing the combina-
tion of manipulator and circuit
board.
• Axes can be moved individually: Recalibrate the home position for
the individual axes that were
affected by the replacement, if
replacing the motor or absolute
encoder.
CAUTION
• Perform the following inspection procedures prior to teaching the
manipulator. If problems are found, correct them immediately, and
be sure that all other necessary tasks have been performed.
– Check for problems in manipulator movement.
– Check for damage to the insulation and sheathing of external
wires.
– Always return the programming pendant to its hook on the
DX100 cabinet after use.
If the programming pendant is inadvertently left on the manipulator, a
fixture, or on the floor, the manipulator or a tool could collide with it
during manipulator movement, possibly causing injury or equipment
damage.
NOTE
Teaching and playback are not possible before the comple-
tion of the home position calibration.
In a system with two or more manipulators, the home posi-
tion of all the manipulators must be calibrated before start-
ing teaching or playback.
