Note 2) TheAngular 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.

Note 1) Pushing Torque accuracy should be ±30%(F.S.) for LER10, ±25%(F.S.) for LER30, ±20%(F.S.) for LER50.
Note 2) TheAngular 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 0oevery 360o. Select INC (Relative) for setting the angle (position).
If setting the angle above 360owith ABS (Absolute), the actuator will not operate correctly.
