Operating and Storage Environments

Warning

1. Envionments to avoid

Avoid using or storing the products in the
following environments which may cause
failures.
If the products need to be used or stored in
those environments, take necessary measures.

a. Place where ambient temperature exceeds

the range of 0℃ to 60℃.

b. Place where ambient humidity exceeds the

range of 25% to 85% RH.

c. Place where condensation occurs due to

sudden temperature change.

d. Place where atmosphere containing corrosive

gas, flammable gas or organic solvent.

e. Place where atmosphere containing

con-ductive powder such as dust and iron
chips, oil mist, salt, or organic solvent, or
splashing cutting chips, dust and cutting oil
(water , liquid) over the products.

f. Place where the products are exposed to

direct sunlight or radiated heat.

g. Place where strong electromagnetic noise is

generated (place where strong electric field,
strong magnetic field or surge is generated).

h. Place where static electricity is discharged or

condition that the products have electrostatic
discharge.

i. Place where strong high frequency is

gene-rated.

j. Place where damages of thunder are

expected.

k. Place where vibration or impact is directly

given to the products.

l. Condition that the products are deformed by

force or weight applied.

2. Do not close any objects which are affected

by magnets.

Since magnets are built in cylinders, do not close
magnetic disks, magnetic cards or magnetic
tapes. The data may be destroyed.

Precaution on Design

Warning

1. There is a possibility of dangerous sudden

action by cylinders if sliding parts of
machi-nery are twisted due to external forces,
etc.

In such cases, human injury may occur; e. g., by

catching hands or feet in the machinery, or
damage to the machinery itself may occur.

2. Provide a cover to minimize the risk of
human injury.

When a driven object or moving parts of a
cylinder may cause the risk of human injury,
design a structure to avoid contact with human
body.

3. Securely tighten all stationary parts and
connected parts of cylinders so that they will
not become loose.

Tighten cylinders securely especially when they
are used in high frequency or in locations where
direct vibration or impact shock, etc. will be
applied to the body of the cylinder.

4. Deceleration circuits or shock absorbers are
needed in some cases.

If a driven object travels at a high speed or is
heavy, impact will not be sufficiently absorbed
only with the cylinder cushion. In such cases,
use a circuit to decelerate the cylinder speed
before the cushion becomes effective or use
external shock absorbers to reduce impact. At
this time, take the rigidity of machinery into
account.

5. Consider possible drop of pressure in circuit
due to power outage.

For cylinders used in clamping mechanism, a
work may become loose due to less clamping
force by pressure drop in circuit at the time of
power outage. Install safety devices to prevent
human injury and machinery damage. Measures
should be taken to prevent drop of hanging or
lifing equipment.

6. Consider possible loss of power sources.

Measures should be taken to protect against
human injury and machinery damage in the
event that there is a loss of air pressure,
electricity or hydraulic power.

7. Design circuit to prevent shooting out of a
driven object.

A driven object is quickly shot out when pressure
is supplied from one side of the piston after air in
the cylinder is exhausted in such cases that
cylinder is actuated by exhaust center type of
directional control valve or started after residual
air is exhausted from the circuit. At this time,
human injury may occur; e.g., by catching hands
or feet in the machinery, or damage to the
machinery itself may occur. Therefore, the
machine should be designed and constructed to
prevent shooting out.

！

！

３

8. Consider emergency stops.

Design the machinery so that human injury
and/or damage to machinery and equipment will
not be caused when machinery is stopped by a
safety device under abnormal conditions, a
power outage or a manual emergency stop.

9. Consider actions when operation is restarted
after an emergency stop or abnormal stop.

Design the machinery so that human injury or
equipment damage will not occur upon restart of
operation. When the cylinder is required to return
to the initial position, provide the equipment with
a safe override.

10.Construct the machinery so that moving

objects and the moving parts of the cylinder
with brake do not come into direct contact with
the human body.

11.Use a balanced circuit in which lurching of the

cylinder is prevented. When operation is locked
in specified intermediate positions of the stroke,
and air pressure is applied to only one side of
the cylinder, the piston will lurch when the lock
is released. This might cause injury or damage
to machinery.

Selection

Warning

1. Confirm the specifications.

The product in this manual is designed to be
used only in industrial compressed air system.
The product should not be used with pressures
or temperatures outside the range of the
specifications, as this may cause damage or
malfunction, etc.

2. Intermediate stop

When cylinder piston is stopped intermediately
by 3-position closed center type of directional
control valve, intermediate stop positions may
not be as precise and exact as hydraulic
operation due to compressibility of air. Valves
and cylinders are not guaranteed for zero air
leakage, and stop position may not be held in a
long period of time. Consult SMC for long term
holding of stop positions.

3. When a cylinder is in a no-load and locked state,

the holding force (maximum static load) is the
lock’s ability to hold a static load that does not
involve vibrations or shocks. To ensure braking
force, the maximum load must be set as described
below.

①For constant static loads, such as for drop

prevention:

35% or less of holding force (Maximum static

load)

Note) For applications such as drop prevention,

consider situations in which the air source
is shut off, and make selections based on
the holding force of the spring locked
state. Do not use the pneumatic lock for
drop prevention purposes.

②When kinetic energy acts upon the cylinder,

such as when effecting an intermediate stop,
there are constraints in terms of the allowable
kinetic energy that can be applied to the
cylinder in a locked state. Refer to the
allowable kinetic energy of the respective
series. Furthermore, during locking, the
mechanism must sustain the thrust of the
cylinder itself, in addition to absorbing the
kinetic energy. Therefore, even within a given
allowable kinetic energy level, there is an
upper limit to the amount of the load that can
be sustained.

- Maximum load for horizontal mounting: 70%
or less of the holding force (Maximum static
load) for spring lock

- Maximum load for vertical mounting: 35% or
less of the holding force (Maximum static
load) for spring lock

③In a locked state, do not apply impact, strong

vibrations or rotational forces. Any impact,
strong vibrations or rotational forces from
external sources could damage or shorten
the life of the lock unit.

④Although the cylinder can be locked in both

directions, be aware that its holding force is
smaller in one of the directions. Holding
force at piston rod extended side is approx.
15% less.

Caution

1. Mount speed controller and adjust cylinder
operation speed gradually from low speed to
a desired speed.

Air Supply

Warning

1. Do not use the product out of the specified

ranges for pressure and temperature to
pre-vent equipment damage and
mal-function.

！

４

①Operating pressure:

Actuating part: 0.1 – 1.0MPa

Braking part

: 0.3 – 0.5MPa

②Fluid & ambient temperature: 0 to 60C

2. Use clean air.

Do not use the product with compressed air
includes chemicals, synthetic materials
(including organic solvents), salinity, corrosive
gases, etc., as this may cause damage or
malfunction.

Caution

1. Install air filter.

Install air filter before and in vicinity of valve. The
filter should be able to collect particles of 5
microns or smaller. A large quantity of drain may
cause malfunction of pneumatic components.

2. Install after cooler, air dryer, auto drain, etc.

Compressed air that includes excessive
condensate may cause malfunction of valve and
other pneumatic equipment. To prevent this,
install after cooler, air dryer, auto drain, etc.

Pneumatic circuit

Warning

1. Be certain to use a pneumatic circuit which will
apply balanced pressure to both sides of the
piston when in a locked stop. (Refer to Chapter 6

for recommended pneumatic circuit.)

In order to prevent the cylinder lurching after a

locked stop, use a circuit which applies balanced
pressure to both sides of the piston when restarting
or when manually releasing the lock, thereby
canceling the force generated by the load in the
direction of piston movement.

2. Use a solenoid valve for unlocking which has a
larger effective area, as a rule 50% or more of
the effective area of the cylinder drive solenoid
valve. (Refer to Chapter 6 for recommended
pneumatic components.)

The larger the effective area is, the shorter the

locking time will be, and stopping accuracy will
be improved.

3. Place the solenoid for unlocking close to the

cylinder, and no farther than the cylinder drive
solenoid valve.

The shorter the distance from the cylinder, the
shorter the overrun amount will be, and stopping
accuracy will be improved.

4. Allow at least 0.5 seconds from a locked stop
(intermediate stop of the cylinder) until release of

the lock.

When the locked stop time is too short, the
piston rod may lurch at a speed greater than the
control speed of the speed controller.

5. When restarting, control the switching signal for
the unlocking solenoid valve so that it acts before
or at the same time as the cylinder drive solenoid
valve.

If the signal is delayed, the piston rod may lurch at
a speed greater than the control speed of the
speed controller.

Installation

Warning

1. Connect the rod end and the load with the lock
released.

2. Ensure that the equipment operates properly

before the use.

3. Operation manual

Do not install the products unless the safety
instruction have been read and understood.
Keep this operation manual on file for future
reference.

Caution

1. Maintenance space

When installing the products, allow space for
maintenance.

2. Installation of jigs

When hardware and nuts are screwed into the
piston rod end, the piston rod should be fully
retracted.
Use double nuts to fix a work since Precision
MONOSASHI-KUN (Scale Reading Cylinder)
does not have any parallel parts at the rod.

3. Do not give strong impact and/or excessive

moment when work is mounted.

External force other than allowable moment may
cause rattle at guide part and/or increase in
sliding resistance.

4. Use the product in such a condition that load

is always applied in the axial direction of the
piston rod.

When load is applied in other directions than
cylinder axial direction, regulate the load itself
by the guide.
Perform a complete centering when cylinder is
mounted.

5. Be careful to avoid scratches or dents, etc. on

the sliding sections of the piston rod.

Wiring

Warning

1. Preparation for wiring

Shut off the power before wiring (including
insertion and removal of connectors). Mount a
protective cover on the terminal block after
wiring.

2. Check the power

Make sure the power has sufficient capacity and
voltages are within the specified range before
wiring.

3. Grounding

Ground terminal block F.G. (Frame Ground).
Do not ground it with devices generating strong
electromagnetic noise.

4. Check wiring

Incorrect wiring may cause damage or
malfunction of the products. Make sure the
wiring is correct before operation.

Caution

1. Separation of signal wires from power wire

Avoid common or parallel wiring of signal and
power wires to prevent malfunction due to noise.

2. Wiring arrangement and fixation

Avoid bending cables sharply at connector part
or electrical entry in wiring arrangement.
Inproper arrangement may cause disconnection
which in turn causes malfunction. Fix cables
close enough not to give excessive force to the
connector.

Piping

Caution

1. Before piping

Remove cutting chips, cutting oil, dust, etc. in
piping by flushing or cleaning before piping.
Care should be taken especially that any cutting
chips, cutting oil, dust, etc. do not exist after a
filter.

2. At piping

①Foreign matter should not enter. Entering of

foreign matter will cause malfunction.

②Cutting chips and sealing materials at piping

threads should not enter valves when piping
and fittings are screwed in. Leave 1.5 to 2
threads when seal tape is used.

Lubrication

Caution

1. Lubrication of cylinder

①This cylinder is pre-lubricated and can be used

without lubrication.

②In case of lubrication, use a equivalent of the

turbine oil type 1 ISO VG32. Once lubrication
is performed, it should be continued since the
initial lubricant flows out causing malfunction.

Adjustment

Caution

1. The locks are manually disengaged when the

cylinder is shipped from the factory. Be sure to
change them to the locked state before using
the cylinder.

2. Adjust the cylinder’s air balance. In the state in
which a load is attached to the cylinder,
disengage the lock and adjust the air pressure
on the rod side and the head side of the cylinder
to obtain a load balance. By maintaining a
proper air balance, the piston rod can be
prevented from lurching when the lock is
disengaged.

3. Adjust the mounting position of detection
devices such as autoswitches.

Sensor unit

Caution

1. Do not remove the sensor unit.
The position and sensitivity of the sensor is
adjusted properly before shipment.

Removing or replacing the sensor may cause
malfunction.

2. Operate the system with an external magnetic
field of 14.5mT or less.
Strong magnetic field in the vicinity may cause
malfunction, since CE2 sensor is magnetic type.

This is equivalent to a magnetic field of
approximately 18cm in radius from a welding area
using a welding current of almost 15,000 amperes.
To use the system in a magnetic field that exceeds
this value, use a magnetic material to shield the
sensor unit

！

！ ！ ！ ！ ！

3. Do not pull sensor cable strongly.

Such action may cause failure.

4. Water shall be kept away from the sensor unit to
avoid failure. (IP65 Protection)

5. Power supply line

Do not mount any switch or relay to power
supply line (12 VDC to 24 VDC).

１．General

1-1 Features

Controller (CEU2) is a special controller designed for Monosashi-kun with Brake. Upon the input, controller

will stop the cylinder, smoothly and precisely at position as inputted.

Stopping positions of Monosashi-kun with Brake are stored into “Step”, ranging from step 1 to 32. Steps will

be grouped together and form as “Program”. CEU2 allows maximum storage of 16 programs.

Following are CEU2’s special feature: -

1. Predictive Control & Learning Function

(Allow High Repeatability and Precision, ±0.5mm)
With learning function, after every execution, brake point will be amended, according to the deviation of

stopping position from setting position.

2.Equipped Function with Retries→If stopping position deviates from setting position’s tolerance, retries
function will execute to revise the brake point.

3. Error Detector

When System is found faulty, error detector will take action, detect and analyze error. Finally, error

messages will be displayed. Thus, ease of debugging time.

4. DIN Rail installation is possible.

1-2 Position Control

1. With controller, valve outputs to achieve precise positioning.

2. For the situation whereby cylinder stopping position does not fall into the tolerance range, retries will
be performed. First, it will retract (30mm), and then extend to achieve setting position.

3. With learning ability, brake point will be recognized and thus lead to precise positioning with taking
into the consideration of factors like loading & pressure condition, momentum & impact when
stopping.

4. Stopping method applied is through air balance and brake to lock the movement. While brake applies
the combination of spring and pneumatic locking method.

5. Position is determined when positioning falls on the setting tolerance range.

6. Position determination will follow the sequence of selected program’s steps.

7. Only programs are available for selection. Program steps are not selectable.

1-3 Positioning at Cylinder Rod End

Do not use cylinder with cushion, if determined position falls at cylinder rod’s end (front or back). This is

due to drastical change of speed occurring at the stroke end will lead to imprecision and easy occuring
of learning error (Err 6).

7. Installation & Wiring

7-1 Installation
7-1-1 Installation of Cylinder

1. During installation of metal fitting onto the end (screw thread) of piston rod, prevent from the
induction of impact and unbalance loading acting upon it.

2. During mounting of cylinder and load, care should be taken not to give misalignment non twist.
Please attach floating joint between the connection.

3. Make sure that pushing force of cylinder act on the centre of load.

4. Do not disassemble cylinder and dismantle sensor from cylinder.

5. Flushing of pipe should be done. Prevent dust & dirt entering into cylinder. Moreover, mist separator
should be used to get rid of water vapor, oil and dirt from the utilized comprised air.

6. When oil is needed to be fed in, use turbine oil class 1 (ISO, VG32).

7. If there is a lot of dust at working environment, use gaiter. Besides that , please take note that
operating temperature should be kept between 0 to 60℃.

8. The total length of air piping (from cylinder to solenoid valve) should be kept below 1m.

7-1-2 Installation of Controller

1. During installation of controller, use M4 bolt and DIN rail.

2. Prevent from direct shining of sun, high or low temperature’s environment.

[Operating temperature range : 0℃～50℃]

3. Do not utilize it at high humidity’s environment.

[Operating humidity range : 25%～85%]

4. Keep it within noise protection material and away from high voltage and power supply wire.

5. Prevent it from mounting in environment containing a lot of dust, salinity, ferrous, or flammable,
corrosive gas.

6. Do not mount it at high vibration and impact environment.

[Proof Vibration : 10～55Hz, range 0.75mm, x, y, z each axis for 2 hours]

7-2 Wiring
7-2-1 The Connection of Power Supply

Power Supply Specification : AC100V±15% (AC85V～AC115V), 50/60Hz

DC24V±10%, 0.4A

Use wire with 0.75mm2 or more in the diameter of wire sectional area and twist it.
FG is meant for preventing lightening strike, use wire, 0.75mm2 or more in the diameter of wire
sectional area, to connect to earth.
If FG is not connected to earth, controller’s noise filter will not be able to function properly. Hence, noise
will be generated and lead to misreading / disoperation of cylinder.

7-2-2 The Connection of Extension Cable
Use specified (SMC) extension cable. Cable length, 5m～20m, with interval of 5m. For distance more

than 20m, use specified transmitter・Receiver box (Model : CE1-H0374)

* Example on cable Connection

Above 20m

Extension Cable

(CE1－R※※)

２３

* Note

1. Clamp and fix the connector and sensor connection to reduce tension acting on them.

2. Separate cable with power line to prevent from the occurring of noise.

3. When cable is necessary to have U bend, set the bending radius to be above 25mm.

9-3 Selection of Dip Switch

No.1･･･The Identification of Origin
OFF････When cylinder stops, if there is no signal feedback from sensor within t1 (Preset data,P7),

counter value will be reseted to “0” and origin is obtained / recognized.
Generally, origin will be at the stroke end.
If origin is set within the stroke, install stopper with respect to the origin.
ON･････When the cylinder stops at origin, situated at the location where auto switch or limit switch

is, and sensor signal is not feedback within t1, counter value will be reset to “0.0” and

origin is obtained.
Install the origin wire to terminal 10.

No.2･･･The Setting of Braking System
OFF････In this state, ON means brake is activated. OFF means brake is in releasing state.
If power supply of controller is cut off, the brake will be in releasing state.

If cylinder is mounted horizontally and the air balance is not achieved, when power is cut

off, the cylinder may keep moving in and out.
If cylinder is mounted vertically, when power is cut off, cylinder rod will fall to the bottom

end, due to its own weight.
ON･････In this state, OFF means brake is activated, ON means brake is in releasing state.
If power supply of controller is cut off, the brake will be in clamping state.

Note: Please take note at piping, which may lead to opposite setting.
No.3･･･The Change of Counter Direction

OFF････The extend direction will be an increment on counter.
The origin is set to be at the retract end.

ON･････The retract direction will be an increment on counter.
The origin is set to be at the extend end.
Note: Please take note at wiring as it may result to opposite

setting.

No.4･･･Delection of Memory: Delete all the input data, back to the initial state.
Generally, set the state to OFF. If input data is required to be deleted, set the state to ON. Next,

reset the power supply through terminal 13. After achieving the initial state, set the state back to
OFF.

10. Driving
10-1 Setting of Origin Direction

Location’s detection method used by Monosashi-kun with brake cylinder is incremental method. Please

set the origin and reference accordingly.

Cylinder stroke end, either extend end or retract end, will be the origin. When dealing with cylinder with

cushion, please do not over monitoring the cushion effect.

When stopper is used, please use shock absorber to prevent from the occurrence of impact and “spring

back” effect.

10-2 Adjustment of Air Balance

Due to the stoppage precision, the rate of occurring of abnormal operation, etc. Will be greatly affected

by the stability of air flow. Please monitor closely to achieve air balancing of cylinder.

Adjustment

1

Manually operate the controller or directional valve & brake valve to shift the piston rod to the center of
stroke.

2

Release the brake and carry out adjustment through pressure reducing valve. Remember, piston rod
should not move during adjustment. Release the brake through brake valve or controller dip switch
No.2.

3

After completion of the adjustment, manually operate brake valve to release and lock the brake system
for a few times. If piston rod is moving during operation, redo the adjustment.

4

Lastly, check it with testing the attainment of desired location.
If piston rod moves to the extreme end or with extraordinarily speed, redo the above adjustment.

Note: If the braking assembly unit has been changed, reset the controller.

４７

There is no braking point within the moving distance.

Solution

: Reset or re-providing power supply.

Countermeasure

: Verify air balancing.

Verify whether there is any impact or momentum acting upon cylinder during
positioning. Verify that there is no entanglement or twisting.
Due to the momentum at the stroke end, setting of “0.0” as origin will lead to
high occurrence of errors.
Therefore, set the origin within “1.0～5.0”. Besides that, it is advisable to make
sure that cylinder rod should return to origin at the end of operation.
For cylinder with cushion, due to drastical change of speed within the stroke,
learning error may arise.
Therefore, for the case of stopping position within 30mm from stroke end is
required, it is advisable not to utilize cylinder with cushion.
