Note 1: Non-standard strokes are manufactured as custom orders.
Note 2: Do not allow collision at either end of the table movement distance at speeds exceeding the "return to origin speed."
In addition, when performing positioning, do not set within a 2 mm range of either end.
Note 3: A reference value for correcting an error in reciprocal operation.
Note 4: Maximum acceleration/deceleration differs depending on the work load. Refer to the "Work Load−Acceleration/Deceleration Graph" in the ball screw drive section of the catalog.
Note 5: Values are guidelines only. Use these values for selecting the motor capacity, etc.
Note 6: Impact resistance: No malfunction occurred when the actuator was tested with a drop tester in both an axial direction and a perpendicular direction to the lead screw. (Test was performed with the actuator in the initial state.)
Vibration resistance: No malfunction occurred in a test ranging between 45 and 2,000 Hz (1 sweep), performed in both an axial direction and a perpendicular direction to the lead screw. (Test was performed with the actuator in the initial state.)

  • *These specifications are tolerance values for the actuator unit, equipped with the standard/reference motor.
  • *Use within these specifications.

Notes

  • *Do not apply load in excess of the specification limits.
  • *Select a suitable actuator by work load and allowable moment. If the product is used outside of the specification limits, the unbalanced load applied to the guide will be excessive and have adverse effects, such as creating play on the guide, degrading accuracy and shortening the lifespan of the product.
  • *Do not use the product in applications where excessive external force or impact force is applied to it. Doing so can cause the product to malfunction.
  • *Refer to the SMC catalog for product information other than what is detailed above.
  • *The product image is a representative image only.

Frequently asked question (FAQ)

Question: Does the LE series have a built-in origin sensor?
Answer: There is no origin sensor.
When an origin sensor is required in use combined with LECS, mount a separate sensor.
As well, origin return in combined use with LECP/LECPA does not require an origin sensor, as the push origin method is used.
[Push origin method: The table is pushed against the stroke end and its position is used as origin reference]
Question: Is horizontal ceiling mounting possible for the LEF Series?
Answer: Ceiling mounting is possible with the same selection as for horizontal.
However, note that longer strokes will lead to seal band deflection.
