Unpacking and Handling
This chapter contains important instructions for unpacking and inspecting the
SCORBOT-ER IX robot arm.
)
Read this chapter carefully before you unpack the SCORBOT-ER IX robot and
controller.
Unpacking the Robot
The robot is packed in expanded foam, as shown in Figure 1-1.
To protect the robot during shipment, a metal plate holds the gripper- mounting
flange to the robot base. The plate is fixed to the flange with three bolts and to the
base with two bolts. Use a 3mm hex socket wrench to detach these bolts.

Handling Instructions
The robot arm weighs 38 kilos (83 pounds). Two people are needed to lift or
move it.
Lift and carry the robot arm by grasping its body and/or base. Do not lift or
carry the robot arm by its upper arm or forearm.
Acceptance Inspection
After removing the robot arm from the shipping carton, examine it for signs of
shipping damage. If any damage is evident, do not install or operate the robot.
Notify your freight carrier and begin appropriate claims procedures.
The following items are standard components in the

Repacking for Shipme nt
Be sure all parts are back in place before packing the robot.
When repacking the robot for shipping, bolt the flange and base to the metal
plate. Failure to do so may result in irreversible damage to the arm, particularly
to the Harmonic Drive transmissions. Also be sure to secure the cables around the
foam spool.
The robot should be repacked in its original packaging for transport.
If the original carton is not available, wrap the robot in plastic or heavy paper. Put
the wrapped robot in a strong cardboard box at least 15 cm (about 6 inches)
longer in all three dimensions than the robot. Fill the box equally around the unit
with resilient packing material (shredded paper, bubble pack, expanded foam
chunks).
Seal the carton with sealing or strapping tape. Do not use cellophane or
masking tape.

Structure
Axis No. Joint Name Mo tio n Motor No.
The SCORBOT-ER IX is a vertical articulated robot, with five revolute joints. With
gripper attached, the robot has six degrees of freedom. This design permits the
end effector to be positioned and oriented arbitrarily within a large work space.
Figures 2-1 and 2-2 identify the joints and links of the mechanical arm.
Each joint is driven by a permanent magnet DC motor via a Harmonic Drive gear
transmission and timing belt.
The movements of the joints are described in the following table:
1 Base Rotates the body. 1
2 Shoulder Raises and lowers th e up pe r ar m . 2
3 Elbow Raises and low er s th e fo re ar m . 3
4 Wrist Pitch Raises and lowers the end effector. 4
5 Wrist Roll Rotates the end effector. 5

Work Envelope
The length of the links and the degree of rotation of the joints determine the
robot’s work envelope. Figure 2-3 shows the dimensions and reach of the
SCORBOT-ER IX, while Figure 2-4 gives a top view of the robot’s work envelope.
The base of the robot is normally fixed to a stationary work surface. It may,
however, be attached to a slidebase, resulting in an extended working range.

The SCORBOT-ER IX is a potentially dangerous machine. Safety during operation
is of the utmost importance. Use extreme caution when working with the robot.
Precautions
The following chapters of this manual provide complete details for proper
installation and operation of the SCORBOT-ER IX. The list below summarizes the
most important safety measures.
1. Make sure the robot base is properly and securely bolted in place.
2. Make sure the cable from the body to the base can move freely during all
movements of the robot’s base axis.
Safety
CHAPTER
3
3. Make sure both the encoder cable and the robot power cable are properly
connected to the controller before it is turned on.
4. Make sure the robot arm has ample space in which to operate freely.
5. Make sure a guardrail or rope has been set up around the SCORBOT-ER IX
operating area to protect both the operator and bystanders.
6. Do not enter the robot’s safety range or touch the robot when the system is in
operation.
7. Press the controller’s EMERGENCY switch before you enter the robot’s
operating area.
8. Turn off the controller’s POWER switch before you connect any inputs or
outputs to the controller.
)
To immediately abort all running programs and stop all axes of motion, do any of
the following:
press the teach pendant’s EMERGENCY button;
use the ACL command A <Enter>;
press the controller’s red EMERGENCY button.

•
Where the ambient temperature drops below or exceeds the specified limits.
•
Where exposed to large amounts of dust, dirt, salt, iron powder, or similar
substances.
•
Where subject to vibrations or shocks.
•
Where exposed to direct sunlight.
•
Where subject to chemical, oil or water splashes.
•
Where corrosive or flammable gas is present.
•
Where the power line contains voltage spikes, or near any equipment which
generates large electrical noises.
3. Do not abuse the robot arm:
•
Do not operate the robot arm if the encoder cable is not connected to the
controller.
•
Do not overload the robot arm. The combined weight of the workload and
gripper may not exceed 2kg (4.4 lb.). It is recommended that the workload be
grasped at its center of gravity.
SCORBOT-ER IX under any of the following conditions:
•
Do not use physical force to move or stop any part of the robot arm.
•
Do not drive the robot arm into any object or physical obstacle.
•
Do not leave a loaded arm extended for more than a few minutes.
•
Do not leave any of the axes under mechanical strain for any length of time.
Especially, do not leave the gripper grasping an object indefinitely.

Installation
Preparations
Before you make any cable connections, set up the system components according
to the following “Preparation” instructions.
Controller and Computer/Terminal Setup
Place the controller and computer at a safe distance from the robot—well outside
the robot’s safety range.
Make sure the setup complies with the guidelines defined in the chapter,
“Safety,” in the ACL
Controller-B
User’s Manual.
CHAPTER
4
Robot Setup
Refer to Figures 4-1, 4-2 and 4-3.
1. Set up the SCORBOT- ER I X
on a sturdy surface with at
least one meter of free space
all around the robot.
2. Note that the robot cable
clamp is located at the
midpoint of the robot’s
horizontal range. Using this
midpoint as a reference, set
up the robot so that it faces in
the proper direction—
towards the application or
machine it will serve.
3. Fasten the base of the robot to
the work surface with three sets
of M8 bolt, washer and nut.
