Resetting the origin 5-98
(3) J3 and J4 axis origin setting (mechanical stopper)
Always perform origin setting of the J3 axis and the J4 axis simultaneously.If the wiring and piping is passed in the
shaft, remove the No.2 arm cover U and operate the origin setting.
Note) If origin setting is carried out with the No.2 arm cover U installed, the origin may not be set up correctly
because the wiring and the piping interfere with the No.2 arm cover U.
1) If the wiring and piping is passed in the shaft,
removes the No.2 arm cover U referring the
Page 72, "5.3.2 Installing/removing the cover"
. It
is not necessary to remove the cover if wiring
and piping is not passed.

play the Origin/Break selection screen.
3) Press the [2] key, and display the Break release
selection screen.
4) Release the brake of the J3 axis.
Input "1" into the J3 axis. Set "0" to other
axes.
5) Confirm the axis for which the brakes are to be
released.
6) Pressing the [F1] key is kept with the enabling
switch of T/B pressed down. The brake is
released while pressing the key.
Note) The brake of the axis shown below
repeats release/lock at the interval in
each about 200ms for dropping the J3
axis slowly.
7) With both hands, slowly move the J3 axis in +
(plus) direction , and contact the axis against
the mechanical stopper.
For safety purposes, the step for releasing the brakes must be carried out by two
workers. One worker must operate the T/B, and the other must support the J3 axis
(shaft). When the brake is released, the J3 axis could drops with its own weight.
