Setup & Operation 1. Safety
1.2 Design and Installation Safety
Only trained personnel should design and install the robot system. Trained
personnel are defined as those who have taken robot system training and
maintenance training classes held by the manufacturer, dealer, or local
representative company, or those who understand the manuals thoroughly and
have the same knowledge and skill level as those who have completed the training
courses.
To ensure safety, a safeguard must be installed for the robot system. For details
on the safeguard, refer to the Installation and Design Precautions in the Safety
chapter of the EPSON RC+ User’s Guide.
The following items are safety precautions for design personnel:
■ Personnel who design and/or construct the robot system with this product must
read the Safety chapter in the EPSON RC+ User’s Guide to understand the
safety requirements before designing and/or constructing the robot system.
Designing and/or constructing the robot system without understanding the safety
requirements is extremely hazardous, may result in serious bodily injury and/or
severe equipment damage to the robot system, and may cause serious safety
problems.
■ The Manipulator and the Controller must be used within the environmental
conditions described in their respective manuals. This product has been
designed and manufactured strictly for use in a normal indoor environment.
Using the product in an environment that exceeds the specified environmental
conditions may not only shorten the life cycle of the product but may also cause
serious safety problems.
WARNING
■ The robot system must be used within the installation requirements described in
the manuals. Using the robot system outside of the installation requirements
may not only shorten the life cycle of the product but also cause serious safety
problems.
Further precautions for installation are mentioned in the chapter Setup &
Operation: 3. Environments and Installation. Please read this chapter carefully to
understand safe installation procedures before installing the robots and robotic
equipment.
4 G3 Rev.1
Setup & Operation 1. Safety
1.3 Operation Safety
The following items are safety precautions for qualified Operator personnel:
■ Please carefully read the Safety-related Requirements in the Safety chapter of
the EPSON RC+ User’s Guide before operating the robot system. Operating
the robot system without understanding the safety requirements is extremely
hazardous and may result in serious bodily injury and/or severe equipment
damage to the robot system.
■ Do not enter the operating area of the Manipulator while the power to the robot
system is turned ON. Entering the operating area with the power ON is
extremely hazardous and may cause serious safety problems as the Manipulator
may move even if it seems to be stopped.
■ Before operating the robot system, make sure that no one is inside the
safeguarded area. The robot system can be operated in the mode for teaching
even when someone is inside the safeguarded area.
The motion of the Manipulator is always in restricted (low speeds and low power)
status to secure the safety of an operator. However, operating the robot system
while someone is inside the safeguarded area is extremely hazardous and may
result in serious safety problems in case that the Manipulator moves
unexpectedly.
WARNING
■ Immediately press the Emergency Stop switch whenever the Manipulator moves
abnormally while the robot system is operated.
■ To shut off power to the robot system, pull out the power plug from the power
source. Be sure to connect the AC power cable to a power receptacle. DO
NOT connect it directly to a factory power source.
■ Before performing any replacement procedure, turn OFF the Controller and
related equipment, and then pull out the power plug from the power source.
Performing any replacement procedure with the power ON is extremely
hazardous and may result in electric shock and/or malfunction of the robot
system.
WARNING
■ Do not insert or pull out the motor connectors while the power to the robot system
is turned ON. Inserting or pulling out the motor connectors with the power ON is
extremely hazardous and may result in serious bodily injury as the Manipulator
may move abnormally, and also may result in electric shock and/or malfunction of
the robot system.
CAUTION
■ Whenever possible, only one person should operate the robot system. If it is
necessary to operate the robot system with more than one person, ensure that all
people involved communicate with each other as to what they are doing and take
all necessary safety precautions.

Setup & Operation 1. Safety
1.4 Emergency Stop
If the Manipulator moves abnormally during operation, immediately press the Emergency
Stop switch. Stops the power supply to the motor, and the arm stops in the shortest
distance with the dynamic brake and mechanical brake.
However, avoid pressing the Emergency Stop switch unnecessarily while the Manipulator
is running normally. Otherwise, the Manipulator may hit the peripheral equipment since
the operating trajectory while the robot system stops is different from that in normal
operation.
To place the system in emergency mode during normal operation, press the Emergency
Stop switch when the Manipulator is not moving.
Refer to the Controller manual for instructions on how to wire the Emergency Stop switch
circuit.
Free running distance in emergency
The operating Manipulator cannot stop immediately after the Emergency Stop switch is
pressed.

Maximum operating speed for CP command is 2000 mm/s on horizontal plane.
*2: In the case where the center of gravity is at the center of Joint #4.
If the center of gravity is not at the center of Joint #4, set the parameter using Inertia command.
*3: The exhaust system in the Cleanroom-model Manipulator draws air from the base interior and arm cover
interior together.
A crack or other opening in the base unit can cause loss of negative air pressure in the outer part of the
arm, which can cause increased dust emission.
Do not remove the maintenance cover on the front of the base.
Seal the exhaust port and the exhaust tube with vinyl tape so that the joint is airtight.
If the exhaust flow is not sufficient, dust particle emission may exceed the specified maximum level.

*4: Conditions of Manipulator during measurement as follows:
Operating conditions : Under rated load, 4-joints simultaneous motion, maximum speed, maximum
acceleration, and duty 50%.
Measurement point : In front of the Manipulator, 1000 mm apart from the motion range, 50 mm above
the base-installed surface.
*5: In general use, Accel setting 100 is the optimum setting that maintains the balance of acceleration and
vibration when positioning.
However, you may require an operation with high acceleration to shorten the cycle time by decreasing the
vibration at positioning. In this case, set Accel to larger than 100.
If you specify a larger Accel value, the frequency of the overload error and over heat may rise during
continuous operation. The use of large Accel setting is recommended only for necessary motions.

Setup & Operation 4. Setting of End Effectors
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 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 button
- Joint #3 cannot be moved up/down by hand because
the electromagnetic 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 button.
Brake release button
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.
- Be careful of the shaft while the brake release button is being pressed because the shaf
t
may be lowered by the weight of the end effector.
Layouts
- When you operate the manipulator with an end effector, the end effector may interfere
with the Manipulator because of the outer diameter of the end effector, the size of the
work piece, or the position of the arms. When designing your system layout, pay
attention to the interference area of the end effector.

4.3 Weight and Inertia Settings
To ensure optimum Manipulator performance, it is important to make sure that the load
(weight of the end effector and work piece) and moment of inertia of the load are within
the maximum rating for the Manipulator, and that Joint #4 does not become eccentric.
If the load or moment of inertia exceeds the rating or if the load becomes eccentric, follow
the steps below, “4.3.1Weight Setting” and “4.3.2 Inertia Setting” to set parameters.
Setting parameters makes the PTP motion of the Manipulator optimal, reduces vibration to
shorten the operating time, and improves the capacity for larger loads. In addition, it
reduces persistent vibration produced when the moment of inertia of the end effector and
work piece is larger that the default setting.
4.3.1 Weight Setting
CAUTION
■ The total weight of the end effector and the work piece must not exceed 3 kg.
The G3 series Manipulators are not designed to work with loads exceeding 3 kg.
Always set the Weight parameters according to the load. Setting a value that is
smaller than the actual load may cause errors, excessive shock, insufficient
function of the Manipulator, and/or shorten the life cycle of parts/mechanisms.
The acceptable weight capacity (end effector and work piece) in G3 series is 1 kg at the
default rating and 3 kg at the maximum. When the load (weight of the end effector and
work piece) exceeds the rating, change the setting of Weight parameter.
After the setting is changed, the maximum acceleration/deceleration speed of the robot
system at PTP motion corresponding to the “Weight Parameter” is set automatically.

4.3.2 Inertia Setting
Moment of Inertia and the Inertia Setting
The moment of inertia is defined as “the ratio of the torque applied to a rigid body and its
resistance to motion”. This value is typically referred to as “the moment of inertia”,
“inertia”, or “GD2”. When the Manipulator operates with additional objects (such as an
end effector) attached to the shaft, the moment of inertia of load must be considered.
CAUTION
■ The moment of inertia of the load (weight of the end effector and work piece)
must be 0.05 kgwm2 or less. The G3 series Manipulators are not designed to
work with a moment of inertia exceeding 0.05 kgwm2.
Always set the moment of inertia parameter to the correct moment of inertia.
Setting a value that is smaller than the actual moment of inertia may cause
errors, excessive shock, insufficient function of the Manipulator, and/or shorten
the life cycle of parts/mechanisms.
The acceptable moment of inertia of load for a G3 series Manipulator is 0.005 kgwm2 at the
default rating and 0.05 kgwm2 at the maximum. When the moment of inertia of the load
exceeds the rating, change the setting of the moment of inertia parameter of the Inertia
command. After the setting is changed, the maximum acceleration/deceleration speed of
Joint #4 at PTP motion corresponding to the “moment of inertia” value is set
automatically.
Moment of inertia of load on the shaft
The moment of inertia of load (weight of the end effector and work piece) on the shaft can

Eccentric Quantity and the Inertia Setting
CAUTION
■ The eccentric quantity of load (weight of the end effector and work piece) must be
150 mm or less. The G3 series Manipulators are not designed to work with
eccentric quantity exceeding 150 mm.
Always set the eccentric quantity parameter according to the eccentric quantity.
Setting a value that is smaller than the actual eccentric quantity may cause
errors, excessive shock, insufficient function of the Manipulator, and/or shorten
the life cycle of parts/mechanisms.
The acceptable eccentric quantity of load in G3 series is 0 mm at the default rating and
150 mm at the maximum. When the eccentric quantity of load exceeds the rating, change
the setting of eccentric quantity parameter of Inertia command. After the setting is
changed, the maximum acceleration/deceleration speed of the Manipulator at PTP motion

4.4 Precautions for Auto Acceleration/Deceleration of Joint #3
When you move the Manipulator in horizontal PTP motion with Joint #3 (Z) at a high
position, the motion time will be faster.
When Joint #3 gets below a certain point, then auto acceleration/deceleration is used to
reduce acceleration/deceleration. (Refer to the figure below.) The higher the position of
the shaft is, the faster the motion acceleration/deceleration is. However, it takes more
time to move Joint #3 up and down. Adjust the position of Joint #3 for the Manipulator
motion after considering the relation between the current position and the destination
position.
The upper limit of Joint #3 during horizontal motion using Jump command can be set by
the LimZ command.

5.1 Motion Range Setting by Pulse Range (for All Joints)
Pulses are the basic unit of Manipulator motion. The motion range of the Manipulator is
controlled by the pulse range between the pulse lower limit and upper limit of each joint.
Pulse values are read from the encoder output of the servo motor.
For the maximum pulse range, refer to the following sections.
The pulse range must be set inside of the mechanical stop range.
5.1.1 Max. Pulse Range of Joint #1
5.1.2 Max. Pulse Range of Joint #2
5.1.3 Max. Pulse Range of Joint #3
5.1.4 Max. Pulse Range of Joint #4.
)
NOTE Once the Manipulator receives an operating command, it checks whether the target
position specified by the command is within the pulse range before operating. If the
target position is out of the set pulse range, an error occurs and the Manipulator does not
move.

coordinate value is “-150”. To change the
value to “-130”, move the lower limit
mechanical stop down “20 mm”. Use calipers
to measure the distance when adjusting the
mechanical stop.
Measure
this distance.
(6) Firmly tighten two lower limit mechanical stop screws (M4 × 15) so that they do no
t
enter the shaft groove.
Recommended tightening torque: 490 N⋅cm (50 kgf⋅cm)
(7) Turn ON the Controller.

(8) Move Joint #3 to its lower limit while pressing the brake release button, and then chec
k
the lower limit position. Do not lower the mechanical stop too far. Otherwise, the
j
oint may not reach a target position.
(9) Calculate the lower limit pulse value of the pulse range using the formula shown below
and set the value.
The result of the calculation is always negative because the lower limit Z coordinate
value is negative.
Lower limit of pulse = lower limit Z coordinate value / 25 × 4096 × 1.8
Example: When lowering the mechanical stop by 20 mm and changing the lowe
r
limit Z coordinate value to “-130” in 150 mm stroke
(-130) / 25 × 4096 ×1.8= -38339

>JRANGE 3,-38339,0 ' Sets the pulse range of Joint #3
(10) Using the Pulse command (Go Pulse command), move Joint #3 to the lower limit
position of the pulse range at low speed. If the mechanical stop range is less than
the pulse range, Joint #3 will hit the mechanical stop and an error will occur. When
the error occurs, either change the pulse range to a lower setting or extend the position
of the mechanical stop within the limit.
If it is difficult to check whether Joint #3 hits a mechanical stop, turn OFF the
Controller and lift the arm top cover to check the condition causing the problem fro
m
the side.

5.4 Standard Motion Range
The following “motion range” diagrams show the standard (maximum) specification.
When each Joint motor is under servo control, the center of Joint #3’s (shaft’s) lowest
point moves in the areas shown in the figure.
“Area limited by mechanical stop” is the area where the center of Joint #3’s lowest point
can be moved when each joint motor is not under servo control.
“Mechanical stop” sets the limited motion range so that the center of Joint #3 cannot move
beyond the area mechanically.
“Maximum space” is the area that contains the farthest reach of the arms. If the
maximum radius of the end effector is over 60 mm, add the “Area limited by mechanical
stop” and “radius of the end effector”. The total value is specified as the maximum area.

Maintenance 1. Safety Maintenance
1. Safety Maintenance
Please read this chapter, this manual, and other relevant manuals carefully to understand
safe maintenance procedures before performing any routine maintenance.
Only authorized personnel who have taken safety training should be allowed to
maintain the robot system.
Safety training is the program for industrial robot operators that follows the laws
and regulations of each nation.
The personnel who have taken safety training acquire knowledge of industrial
robots (operations, teaching, etc.), knowledge of inspections, and knowledge of
related rules/regulations.
The personnel who have completed the robot system-training and maintenance-
training classes held by the manufacturer, dealer, or locally-incorporated
company are allowed to maintain the robot system.
■ Do not remove any parts that are not covered in this manual. Follow the
maintenance procedure strictly as described in this manual. Improper removal
of parts or improper maintenance may not only cause improper function of the
robot system but also serious safety problems.
■ Keep away from the Manipulator while the power is ON if you have not taken the
training courses. Do not enter the operating area while the power is ON.
Entering the operating area with the power ON is extremely hazardous and may
cause serious safety problems as the Manipulator may move even it seems to be
stopped.
■ When you check the operation of the Manipulator after replacing parts, be sure to
check it while you are outside of the safeguarded area. Checking the operation
of the Manipulator while you are inside of the safeguarded area may cause
serious safety problems as the Manipulator may move unexpectedly.
WARNING
■ Before operating the robot system, make sure that both the Emergency Stop
switches and safeguard switch function properly. Operating the robot system
when the switches do not function properly is extremely hazardous and may
result in serious bodily injury and/or serious damage to the robot system as the
switches cannot fulfill their intended functions in an emergency.
■ To shut off power to the robot system, pull out the power plug from the power
source. Be sure to connect the AC power cable to a power receptacle. DO
NOT connect it directly to a factory power source.
WARNING
■ Before performing any replacement procedure, turn OFF the Controller and
related equipment, and then pull out the power plug from the power source.
Performing any replacement procedure with the power ON is extremely
hazardous and may result in electric shock and/or malfunction of the robot
system.
G3 Rev.1 67
Maintenance 1. Safety Maintenance
68 G3 Rev.1
CAUTION
■ Be sure to connect the cables properly. Do not allow unnecessary strain on the
cables. (Do not put heavy objects on the cables. Do not bend or pull the cables
forcibly.) The unnecessary strain on the cables may result in damage to the
cables, disconnection, and/or contact failure. Damaged cables, disconnection,
or contact failure is extremely hazardous and may result in electric shock and/or
improper function of the robot system.
2. General Maintenance
This chapter describes maintenance inspections and procedures. Performing maintenance
inspections and procedures properly is essential for preventing trouble and ensuring safety.
Be sure to perform the maintenance inspections in accordance with the schedule.
2.1 Schedule for Maintenance Inspection
Inspection points are divided into five stages: daily, monthly, quarterly, biannual, and
annual. The inspection points are added every stage.
If the Manipulator is operated for 250 hours or longer per month, the inspection points
must be added every 250 hours, 750 hours, 1500 hours, and 3000 hours operation.

2.3 Greasing
The ball screw spline and reduction gear units need greasing regularly. Only use the
grease specified in the following table.
CAUTION
■ Keep enough grease in the Manipulator. Operating the Manipulator with
insufficient grease will damage sliding parts and/or result in insufficient function of
the Manipulator. Once the parts are damaged, a lot of time and money will be
required for the repairs.

2.4 Tightening Hexagon Socket Head Cap Bolts
Hexagon socket head cap bolts are used in places where mechanical strength is required.
(A hexagon socket head cap bolt will be called a “bolt” in this manual.) These bolts are
fastened with the tightening torques shown in the following table.
When it is necessary to refasten these bolts in some procedures in this manual (except
special cases as noted), use a torque wrench so that the bolts are fastened with the
appropriate tightening torques as shown below.
Bolt Tightening Torque Refer below for the set screw.
M3 245 N⋅cm (25 kgf⋅cm) Set Screw Tightening Torque
M4 490 N⋅cm (50 kgf⋅cm) M4 245 N⋅cm (25 kgf⋅cm)
M5 980 N⋅cm (100 kgf⋅cm) M5 392 N⋅cm (40 kgf⋅cm)
M6 1,760 N⋅cm (180 kgf⋅cm)
M8 3,720 N⋅cm (380 kgf⋅cm)
M10 7,350 N⋅cm (750 kgf⋅cm)
M12 12,740 N⋅cm (1,300 kgf⋅cm)
We recommend that the bolts aligned on a circumference should be fastened in a crisscross
pattern as shown in the figure below.

8
Bolt hole
Do not fasten all bolts securely at one time.
Divide the number of times that the bolts are
fastened into two or three and fasten the bolts
securely with a hexagonal wrench. Then, use
a
torque wrench so that the bolts are fastened with
tightening torques shown in the table above.
2.5 Matching Origins
After parts have been replaced (motors, reduction gear units, a brake, timing belts, a ball
screw spline unit, etc.), the Manipulator cannot operate properly because a mismatch
exists between the origin stored in each motor and its corresponding origin stored in the
Controller. After replacing the parts, it is necessary to match these origins.
The method of calibration is different depending on the software used. Refer to
Maintenance: 13. Calibration and follow the steps that pertain to the software you are
using.
For calibration, the pulse values for a specific position must be recorded in advance.
Before replacing parts, select easy point (pose) data from the registered point data to check
the accuracy. Then, follow the steps below to display the pulse values and record them.
