These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.”
They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC),
Japan Industrial Standards (JIS)*1) and other safety regulations*2).

*1) ISO 4414: Pneumatic fluid power -- General rules relating to systems

ISO 4413: Hydraulic fluid power -- General rules relating to systems
IEC 60204-1: Safety of machinery -- Electrical equipment of machines (Part 1: General requirements)
ISO 10218-1992: Manipulating industrial robots -- Safety
JIS B 8370: General rules for pneumatic equipment.
JIS B 8361: General rules for hydraulic equipment.
JIS B 9960-1: Safety of machinery – Electrical equipment for machines. (Part 1: General requirements)
JIS B 8433-1993: Manipulating industrial robots - Safety. etc.
*2) Labor Safety and Sanitation Law, etc.

Caution

Caution indicates a hazard with a low level of risk which, if not avoided, could result in minor or

moderate injury.

Warning

Warning indicates a hazard with a medium level of risk which, if not avoided, could result in

death or serious injury.

Danger

Danger indicates a hazard with a high level of risk which, if not avoided, will result in death or

serious injury.

Warning

1. The compatibility of the product is the responsibility of the person who designs the equipment or
decides its specifications.

Since the product specified here is used under various operating conditions, its compatibility with specific
equipment must be decided by the person who designs the equipment or decides its specifications based on
necessary analysis and test results.
The expected performance and safety assurance of the equipment will be the responsibility of the person who
has determined its compatibility with the product.
This person should also continuously review all specifications of the product referring to its latest catalog
information, with a view to giving due consideration to any possibility of equipment failure when configuring the
equipment.

2. Only personnel with appropriate training should operate machinery and equipment.

The product specified here may become unsafe if handled incorrectly.
The assembly, operation and maintenance of machines or equipment including our products must be
performed by an operator who is appropriately trained and experienced.

3. Do not service or attempt to remove product and machinery/equipment until safety is confirmed.

The inspection and maintenance of machinery/equipment should only be performed after measures to prevent
falling or runaway of the driven objects have been confirmed.
When the product is to be removed, confirm that the safety measures as mentioned above are implemented
and the power from any appropriate source is cut, and read and understand the specific product precautions
of all relevant products carefully.
Before machinery/equipment is restarted, take measures to prevent unexpected operation and malfunction.

4. Contact SMC beforehand and take special consideration of safety measures if the product is to
be used in any of the following conditions.

1) Conditions and environments outside of the given specifications, or use outdoors or in a place exposed to
direct sunlight.

2) Installation on equipment in conjunction with atomic energy, railways, air navigation, space, shipping,

vehicles, military, medical treatment, combustion and recreation, or equipment in contact with food and
beverages, emergency stop circuits, clutch and brake circuits in press applications, safety equipment or other
applications unsuitable for the standard specifications described in the product catalog.

3) An application which could have negative effects on people, property, or animals requiring special safety
analysis.

4) Use in an interlock circuit, which requires the provision of double interlock for possible failure by using a

mechanical protective function, and periodical checks to confirm proper operation.

Note 2) The Angular acceleration, angular deceleration and angular speed may fluctuate due to variations in the moment of inertia.
Refer to the catalog.
Note 3) The speed and force may change depending on the cable length, load and mounting conditions.Furthemore, if the cable length

exceeds 5m then it will decrease by up to 10% for each 5m.(At 15m : Reduced by up to 20%)
Note 4) A reference value for correcting an error in reciprocal operation.
Note 5) Impact resistance: No malfunction occured when the rotary actuator was tested with a drop tester in both an axial direction and a

perpendicular direction to the lead screw. (The test was performed with the rotary actuator in the initial state)

Vibration resistance: No malfunction occured in a test ranging between 45 to 2000 Hz. Test was performed in both an axial direction

and a perpendicular direction to the lead screw.

(The test was performed with the rotary actuator in the initial state)
Note 6) The “Power consumption” (including the controller) is for when the actuator is operating.
Note 7) The “Standby power consumption when operating” (including the controller) is for when the actuator is stopped in the set

position during the operation, except for during the pushing operation.

Note 8) The “Momentary max.power consumption” (including the controller) is for when the actuator is operating.

This value can be used for the selection of the power supply.

2.1.2 How to Order

Caution

The actuator body and controller are sold as a package.

If When only the actuator is purchased separately, confirm that the combination of the controller, which
you have and the actuator is compatible. / See 5.3 Caution (1) on p. 36

<Be sure to check the following before use.>

(1) Check that actuator label for model number.

This matches the controller.

(2) Check Parallel I/O configuration matches (NPN or PNP).

Note 1) Pushing Torque accuracy should be ±30%(F.S.) for LER10, ±25%(F.S.) for LER30, ±20%(F.S.) for LER50.

Note 2) The Angular acceleration, angular deceleration and angular speed may fluctuate due to variations in the moment of inertia.
Refer to the catalog.

Note 3) The speed and force may change depending on the cable length, load and mounting conditions.Furthermore, if the

cable length exceeds 5m then it will decrease by up to 10% for each 5m.(At 15m : Reduced by up to 20%)
Note 4) A reference value for correcting an error in reciprocal operation.
Note 5) Impact resistance: No malfunction occured when the rotary actuator was tested with a drop tester in both an axial

direction and a perpendicular direction to the lead screw.

(The test was performed with the rotary actuator in the initial state)

Vibration resistance: No malfunction occured in a test ranging between 45 to 2000 Hz. Test was performed in both an

axial direction and a perpendicular direction to the lead screw.

(The test was performed with the rotary actuator in the initial state)
Note 6) The “Power consumption” (including the controller) is for when the actuator is operating.
Note 7) The “Standby power consumption when operating” (including the controller) is for when the actuator is stopped

in the set position during the operation, except for during the pushing operation.

Note 8) The “Momentary max.power consumption” (including the controller) is for when the actuator is operating.

This value can be used for the selection of the power supply.

Note 9) The Monitor angle is reset to 0o every 360o. Select INC (Relative) for setting the angle (position).

If setting the angle above 360o with ABS (Absolute), the actuator will not operate correctly.
