Step 2 Check How to Operate
This product is a controller dedicated for servo press function. (It cannot conduct positioner operation or pulse
train control.)
☆ What is Servo Press Function
It is a pressing method using the servomotor. There are two types of control available. One is the velocity
control mode which conducts positioning operation to the set position, and the other is the force control mode
which conducts pressing with the set load considered as the target pressing force.
CB/CGB Type LC/LCG Type
☆ What is Fieldbus Control
(Reference) What is Positioner Operation…(Unavailable) (Reference) What is Pulse Train Control…(Unavailable)
Operation is conducted by setting the target position,
velocity and so on in the position table in advance and
indicating the position number.
Send the pulse corresponding to the movement amount
of the actuator to the controller from a tool such as the
positioning unit.
Fieldbus communication is used instead of connected with and controlled by PIO.
Without using position data, operation can also be made by inputting numbers directly.

Check the operation modes and control methods available on the controller you have purchased.
It can be defined on the controller model code shown on the label in the front face of the controller.

●For PLC Feature Equipped
Caution Set it away from the mechanical end or peripherals as much as possible when turning the servo ON.
Move it apart when it interferes with peripherals. It may generate an alarm if it hits to the mechanical end or
peripherals when the servo is turned ON. Also, in case the actuator is installed in vertical orientation, turning
ON/OFF the servo at the same spot may cause a slight drop by the self-gravity. Pay attention not to pinch
your finger or damage a work piece.
Caution Pay attention not to pinch your finger or damage a work piece by dropping the actuator with self-gravity when
it is released compulsorily with the brake release switch placed on the front panel of this controller.
Caution This controller is equipped with a safety velocity function to make the operation in low speed compulsorily.
It is recommended to have this function activated in the first operation.

(2) Cable Wiring
● Use our company’s genuine cables for connecting between the actuator
and controller, and for the teaching tool.
● Do not scratch on the cable. Do not bend it forcibly. Do not pull it. Do not
coil it around. Do not insert it. Do not put any heavy thing on it. Failure to
do so may cause a fire, electric shock or malfunction due to leakage or
continuity error.
● Perform the wiring for the product, after turning OFF the power to the
unit, so that there is no wiring error.
● When the direct current power (+24V) is connected, take the great care
of the directions of positive and negative poles. If the connection
direction is not correct, it might cause a fire, product breakdown or
malfunction.
● Connect the cable connector securely so that there is no disconnection
or looseness. Failure to do so may cause a fire, electric shock or
malfunction of the product.
● Never cut and/or reconnect the cables supplied with the product for the
purpose of extending or shortening the cable length. Failure to do so
may cause the product to malfunction or cause fire.
(3) Grounding
● The grounding operation should be performed to prevent an electric
shock or electrostatic charge, enhance the noise-resistance ability and
control the unnecessary electromagnetic radiation.
● For the ground terminal on the AC power cable of the controller and the
grounding plate in the control panel, make sure to use a twisted pair
cable with wire thickness 0.5mm2 (AWG20 or equivalent) or more for
grounding work. For security grounding, it is necessary to select an
appropriate wire thickness suitable for the load. Perform wiring that
satisfies the specifications (electrical equipment technical standards).
● Perform Class D Grounding (former Class 3 Grounding with ground
resistance 100 or below).

(4) Safety Measures
● When the work is carried out with 2 or more persons, make it clear who
is to be the leader and who to be the follower(s) and communicate well
with each other to ensure the safety of the workers.
● When the product is under operation or in the ready mode, take the
safety measures (such as the installation of safety and protection fence)
so that nobody can enter the area within the robot’s movable range.
When the robot under operation is touched, it may result in death or
serious injury.
● Make sure to install the emergency stop circuit so that the unit can be
stopped immediately in an emergency during the unit operation.
● Take the safety measure not to start up the unit only with the power
turning ON. Failure to do so may start up the machine suddenly and
cause an injury or damage to the product.
● Take the safety measure not to start up the machine only with the
emergency stop cancellation or recovery after the power failure. Failure
to do so may result in an electric shock or injury due to unexpected
power input.
● When the installation or adjustment operation is to be performed, give
clear warnings such as “Under Operation; Do not turn ON the power!”
etc. Sudden power input may cause an electric shock or injury.
● Take the measure so that the work part is not dropped in power failure or
emergency stop.
● Wear protection gloves, goggle or safety shoes, as necessary, to secure
safety.
● Do not insert a finger or object in the openings in the product. Failure to
do so may cause an injury, electric shock, damage to the product or fire.
● When releasing the brake on a vertically oriented actuator, exercise
precaution not to pinch your hand or damage the work parts with the
actuator dropped by gravity.
5 Teaching ● When the work is carried out with 2 or more persons, make it clear who
is to be the leader and who to be the follower(s) and communicate well
with each other to ensure the safety of the workers.
● Perform the teaching operation from outside the safety protection fence,
if possible. In the case that the operation is to be performed unavoidably
inside the safety protection fence, prepare the “Stipulations for the
Operation” and make sure that all the workers acknowledge and
understand them well.
● When the operation is to be performed inside the safety protection
fence, the worker should have an emergency stop switch at hand with
him so that the unit can be stopped any time in an emergency.
● When the operation is to be performed inside the safety protection
fence, in addition to the workers, arrange a watchman so that the
machine can be stopped any time in an emergency. Also, keep watch on
the operation so that any third person can not operate the switches
carelessly.
● Place a sign “Under Operation” at the position easy to see.
● When releasing the brake on a vertically oriented actuator, exercise
precaution not to pinch your hand or damage the work parts with the
actuator dropped by gravity.
* Safety protection Fence : In the case that there is no safety protection
fence, the movable range should be indicated.
