Setting Of End Effectors; Attaching An End Effector - Epson LS3-401 series Manipulator Manual

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.
■ 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.
CAUTION
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 robot 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 : LS3
- Joint #3 cannot be moved up/down by hand because
the solenoid brake is applied to the joint while power
to the robot system is turned OFF.
This prevents the shaft from hitting peripheral
equipment in the case that the shaft is lowered 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 while attaching an end
effector, turn ON the Controller and press the brake
release switch.
This button switch is a momentary-type; the brake is released only while the button
switch is being pressed.
- Be careful of the shaft while the brake release switch is being pressed because the shaft
may be lowered by the weight of the end effector.
