4. Setting of End Effectors
4.1 Attaching an End Effector
Users are responsible for making their own end effector(s). Before attaching an end
effector, observe these guidelines.
CAUTION
■
If you use an end effector equipped with a gripper or chuck, connect wires and/or
pneumatic
tubes properly so that the gripper does not release the work piece
when the
power to the robot system is turned OFF. Improper connection of the
wires and
/or pneumatic tubes may damage the robot system and/or work piece
as the work piece is released when the Emergency Stop switch is pressed.
I/O
outputs are configured at the factory so that they are automatically shut off (0)
by power disconnection, the
Emergency Stop switch, or the safety features of the
robot system
.
Shaft
-
Attach
an end effector to the lower end of the shaft.
For the shaft dimensions,
and the overall dimensions of the Manipulator, refer to
Setup
& Operation:
2. Specifications.
-
Do not
move the upper limit mechanical stop on the lower side of the shaft.
Otherwise, when
“Jump motion”
is performed, the upper limit mechanical stop may hit
the Manipulator, and the r
obot system may not function properly.
-
Use a split muff coupling with an
M4 bolt or larger to attach the end effector to the
shaft.
Brake release switch
-
Joint #3
and #4 cannot be moved up/down and rotate
by hand because the solenoid brake is applied to the
joint while power
to the robot system is turned OFF.
This prevents t
he shaft from
hitting peripheral
equipment in the case that the shaft is lowered
and
the
end effector is rotated by the weight of the end
effector when the
power
is disconnected during
operation,
or when the motor is turned OFF even
though the
power is turned ON.
To move Joint #3 up/down or rotate Joint #4 while
attaching an end effector
, turn ON the Controller and
move the joint up/down or rotate the joint while
pressing
the brake release switch.
Brake release switch
The shaft may be lowered by
the weight of the end effector.
This button
switch is a momentary-type; the brake is released only while the button
switch
is being pressed.
The respective brakes for Joints #3 and #4 are released simultaneously.
-
Be careful of the
shaft falling and rotating while the brake release switch is
pressed
because
the shaft may be lowered by the weight of the end effector.
