Note 1) The middle stroke other than the above are produced upon receipt of order.
Note 2) Horizontal: The maximum value of the workload for the positioning operation. For the pushing operation the maximum workload is
equal to the "Vertical workload"An external guide is necessary to support the workload. The actual workload and transfer
speed will depend on the type of external guide.
Vertical: The speed is dependent on the workload.Check the catalog data for the selected model.
The figures shown in ( ) are the maximum acceleration/deceleration values.Set these values to be 3000mm/s² or less.
Note 3) The accuracy of the pushing force is ±20% of the max. pushing force.
Note 4) The setting range for the "Pushing force" is from 35% to 85% (LEY25 is upper bound 65%).
For details of setting range and notes, refer 7.2 "INP output signal" p.41.
It is possible that the "Pushing force" and the "Duty ratio" will change dependent on the set value.
Note 5) "Pushing speed” is the allowable speed for the pushing operation.
Note 6) Impact resistance:
No malfunction occurred when the actuator was tested with a drop tester in both an axial direction and perpendicular
direction to the lead screw.
(The test was performed with the actuator in the initial state.)
Vibration resistance:
No malfunction occurred in a test ranging between 45 to 2000 Hz, when the actuator was tested in both an axial
direction and a perpendicular direction to the lead screw.
(The test was performed with the actuator in the initial state.)
Note 7) The “Power consumption” (including the controller) is for when the actuator is operating.
Note 8) The “Standby power consumption when operating” (including the controller) is for when the actuator is stopped in the set
position during the operation, except during the pushing operation.
Note 9) 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 10) With lock oniy.
Note 11) For an actuator with lock, add the power consumption for the lock.
