1. Safety

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.

WARNING

■ 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.
■ 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.

1. Safety

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.

WARNING

■ 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.
■ 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.

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.
■ 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.

1. Safety

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.
The free running time/angle/distance of the Manipulator are shown below. However,
remember that the values vary depending on following conditions.

*1: The exhaust system in the Cleanroom-model Manipulator (G10/G20-***C*) draws air from the base
interior and arm cover interior.
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.

*5: 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.
*6: 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.

CAUTION

Before attaching an end

■ 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
- Joints #3 and #4 cannot be moved up/down by hand because the electromagnetic brake
is applied to the joints while power to the robot system is turned OFF. This prevents
the shaft from hitting peripheral equipment and rotating 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 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 button.
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.

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 operation 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.

4.3.2 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

■ G10 series
The moment of inertia of the load (weight of the end effector and work piece)
must be 0.25 kgwm2 or less. The G10 series Manipulators are not designed to
work with a moment of inertia exceeding 0.25 kgwm2.
G20 series
The moment of inertia of the load (weight of the end effector and work piece)
must be 0.45 kgwm2 or less. The G20 series Manipulators are not designed to
work with a moment of inertia exceeding 0.45 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 G10 series and G20 series Manipulators are
as follows.

CAUTION

■ The eccentric quantity of load (weight of the end effector and work piece) must be

to work with eccentric quantity exceeding 200 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 G10 series and G20 series Manipulators is 0

Precautions for Auto Acceleration/Deceleration of Joint #3
When you move the Manipulator horizontally 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 can be set by the LimZ command.

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.

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.

(5) Move the arm by hand until it touches the mechanical stops, and make sure that the
arm does not hit any peripheral equipment during operation.
(6) Operate the joint changed at low speeds until it reaches the positions of the minimum
and maximum pulse range. Make sure that the arm does not hit the mechanical
stops. (Check the position of the mechanical stop and the motion range you set.)
Example:

EPSON

Setup & Operation

5. Motion Range

In this example, Joint #1 is moved to the center of its motion range (pulse value:
2621440) when checking Joint #2.
If the arm is hitting the mechanical stops or if an error occurs after the arm hits the
mechanical stops, either reset the pulse range to a narrower setting or extend the
positions of the mechanical stops within the limit.

5.2.2

Setting the Mechanical Stop of Joint #3
NOTE

)

This method applies only to the Standard-model Manipulator (G10/G20-***S*).
For the Cleanroom-model (G10/G20-***C*), the motion range set with the Joint #3
mechanical stop cannot be changed.
(1) Turn ON the Controller and turn OFF the motors using the Motor OFF command.
(2) Push up the shaft while pressing the brake
release button.

Lower limit mechanical stop : 2-M5×6
Brake release button

Do not push the shaft up to its upper limit or
it will be difficult for the arm top cover to
be removed. Push the shaft up to a
position where the Joint #3 mechanical stop
can be changed.
NOTE

)

When you press the brake release button,
the shaft may lower and rotate due to the
weight of the end effector. Be sure to hold
the shaft by hand while pressing the button.

Shaft

(3) Turn OFF the Controller.
(4) Loosen the lower limit mechanical stop screw (2-M5×6).
NOTE

)

A mechanical stop is mounted on both the top and bottom of Joint #3. However, only
the position of the lower limit mechanical stop on the top can be changed. Do not
remove the upper limit mechanical stop on the bottom because the calibration point of
Joint #3 is specified using the stop.
(5) The upper end of the shaft defines the
Measure this distance
maximum stroke. Move the lower limit
mechanical stop down by the length you
want to limit the stroke.
For example, when the lower limit
mechanical stop is set at “420 mm” stroke,
the lower limit Z coordinate value is
“-420”. To change the value to “-100”,
move the lower limit mechanical stop
down “330 mm”. Use calipers to
measure the distance when adjusting the
mechanical stop.

(6) Firmly tighten two setscrews which are open at a 120 degree interval so that they do
not enter the shaft groove.
Recommended tightening torque: 980 N⋅cm (100 kgf⋅cm)
(7) Turn ON the Controller.
(8) Move Joint #3 to its lower limit while pressing the brake release button, and then
check the lower limit position. Do not lower the mechanical stop too far.
Otherwise, the joint 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.
G10-851S (Z: 180mm)
Lower limit of pulse = lower limit Z coordinate value / 25 × 131072 × (66 / 32)
G10-854S (Z: 420mm)
Lower limit of pulse = lower limit Z coordinate value / 50 × 131072 × (66 / 32)
Example:

EPSON
RC+

Execute the following command from the [Command Window].
>JRANGE 3,-1081344,0
' Sets the pulse range of Joint #3
Example:

EPSON
RC+

When lowering the mechanical stop by 80 mm and changing the lower
limit Z coordinate value to “-100” in 180 mm stroke
(−100) / 25 × 131072 × (66/32) = −1081344

When lowering the mechanical stop by 330 mm and changing the lower
limit Z coordinate value to “-100” in 420 mm stroke
(−100) / 50 × 131072 × (66/32) = −540672

Execute the following command from the [Command Window].
>JRANGE 3,-540672,0
' 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.
NOTE

)

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 from
the side.

5. Motion Range

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.
