2 General Instructions
2.1 Wiring
Warning
Adjusting, mounting or wiring change should not be done before
disconnecting the power supply to the product.
Electrical shock, malfunction and damage can result.
Do not disassemble the cables.
Use only specified cables.
Do not connect or disconnect the wires, cables and connectors
when the power is turned on.
Caution
Wire the connector correctly and securely.
Check the connector for polarity and do not apply any voltage to the
terminals other than those specified in the Operation Manual.
Take appropriate measures against noise.
Noise in a signal line may cause malfunction. As a countermeasure
separate the high voltage and low voltage cables, and shorten the wiring
lengths, etc.
Do not route input/output wires and cables together with power or
high voltage cables.
The product can malfunction due to interference of noise and surge
voltage from power and high voltage cables to the signal line. Route the
wires of the product separately from power or high voltage cables.
Take care that actuator movement does not catch cables.
Operate with all wires and cables secured.
Avoid bending cables at sharp angles where they enter the product.
Avoid twisting, folding, rotating or applying an external force to the
cable.
Risk of electric shock, wire breakage, contact failure and loss of control of
the product can happen.
Select “Robotic cables” in case of inflecting cable (encoder/ motor/
rock) repeatedly.
Refer to the “Driver operation manual” for the bending life due to the
bending radius of the cable.
2 General Instructions (continued)
Confirm correct insulation of the product.
Poor insulation of wires, cables, connectors, terminals etc. can cause
interference with other circuits. Also there is the possibility that excessive
voltage or current may be applied to the product causing damage.
2.2 Transportation
Caution
Do not carry or swing the product by the cables.
2.3 Mounting
Warning
Observe the tightening torque for screws.
Unless stated otherwise, tighten the screws to the recommended torque
for mounting the product.
Do not make any alterations to this product.
Alterations made to this product may lead to a loss of durability and
damage to the product, which can lead to human injury and damage to
other equipment and machinery.
When an external guide is used, connect the moving parts of the
product and the load in such a way that there is no interference at
any point within the stroke.
Do not scratch or dent the sliding parts of the table or mounting face etc.,
by striking or holding them with other objects. The components are
manufactured to precise tolerances, so that even a slight deformation
may cause faulty operation or seizure.
Do not use the product until you verify that the equipment can be
operated correctly.
After mounting or repair, connect the power supply to the product and
perform appropriate functional inspections to check it is mounted
correctly.
When attaching to the work piece, do not apply strong impact or
large moment.
If an external force over the allowable moment is applied, it may cause
looseness in the guide unit, an increase in sliding resistance or other
problems.
Maintenance space
Allow sufficient space for maintenance and inspection.
2.4 Handling
Warning
Do not touch the motor while in operation.
The surface temperature of the motor can increase to approx. 80°C due
to operating conditions.
Energizing alone may also cause this temperature increase.
As it may cause burns, do not touch the motor when in operation.
If abnormal heating, smoking or fire, etc. occurs in the product,
immediately turn off the power supply.
Immediately stop operation if abnormal operation noise or vibration
occurs.
If abnormal operation noise or vibration occurs, the product may have
been mounted incorrectly. Unless operation of the product is stopped for
inspection, the product can be seriously damaged.
Never touch the rotating part of the motor or the moving part of the
actuator while in operation.
There is a serious risk of injury.
When installing, adjusting, inspecting or performing maintenance
on the product, driver and related equipment, be sure to turn off the
power supply to each of them. Then, lock it so that no one other
than the person working can turn the power on, or implement
measures such as a safety plug.
Caution
Keep the driver and product combined as delivered for use.
The product is set in parameters for shipment.
If it is combined with a different product parameter, failure can result.
2 General Instructions (continued)
Check the product for the following points before operation.
• Damage to electric driving line and signal lines.
• Looseness of the connector to each power line and signal line.
• Looseness of the actuator/cylinder and driver mounting.
• Abnormal operation.
• Stop function
When more than one person is performing work, decide on the
procedures, signals, measures and resolution for abnormal
conditions before beginning the work.
Also designate a person to supervise the work, other than those
performing the work.
An operation test should be performed at low speed, start the test at
a predefined speed, after confirming there are no problems.
Actual speed of the product will be changed by the workload.
Before selecting a product, check the catalogue for the instructions
regarding selection and specifications.
Do not apply a load, impact or resistance in addition to a transferred
load during return to origin.
In the case of the return to origin by pushing force, additional force will
cause displacement of the origin position since it is based on detected
motor torque.
Do not remove the nameplate.
2.5 Actuator with lock
Warning
Do not use the lock as a safety lock or a control that requires a
locking force.
The lock used is designed to prevent dropping of work piece.
For vertical mounting, use the product with a lock.
If the product is not equipped with a lock, the product will move and drop
the work piece when the power is removed.
"Measures aga
inst drops,” means preventing a work piece from
dropping due to its weight when the product operation is stopped
and the power supply is turned off.
Do not apply an impact load or strong vibration while the lock is
activated.
If an external impact load or strong vibration is applied to the product, the
lock will lose its holding force and damage to the sliding part of the lock or
reduced lifetime can result. The same situation will happen when the
lock slips due to a force higher than its holding force, as this will
accelerate the wear to the lock.
Do not apply liquid, oil or grease to the lock or its surroundings.
When liquid, oil or grease is applied to the sliding part of the lock, its
holding force will be reduced significantly.
Take “measures against drops” and check that safety is assured
before mounting, adjustment and inspection of the product.
If the lock is released with the product mounted vertically, a work piece
can drop due to its weight.
2.6 Please refer to the auto switch
references in “Best Pneumatics”
when an auto switch is to be used.
2.7 Unpacking
Caution
Check the received product is as ordered.
If a different product is installed from the one ordered, injury or damage
could result.
