*1 Gripping force should be from 10 to 20 times the workpiece weight. Moving force should be 150% when releasing the workpiece. Gripping force accuracy should be: LEHF10: ±30% (F.S.), LEHF20: ±25% (F.S.), LEHF32/LEHF40: ±20% (F.S.). Gripping the workpiece with a heavy attachment and fast pushing speed may not satisfy the product specifications. In this case, decrease the weight and lower the pushing speed.
*2 Pushing speed should be set within the range during pushing (gripping) operation. Otherwise, it may cause malfunction. The open/close speed and pushing speed are for both fingers. The speed for one finger is 1/2 this value.
*3 The speed and force may change depending on the cable length, load, mounting conditions, etc. Furthermore, if the cable length exceeds 5 m, then the speed and force will decrease by up to 10% for each 5 m. (At 15 m: reduced by up to 20%)
*4 Repeated length measurement accuracy means dispersion (value on the controller monitor) when the workpiece is repeatedly held in the same position.
*5 There is no effect on the backlash during pushing (gripping). Make the stroke longer by the amount of backlash when opening.
*6 Repeatability means the variation of the gripping position (workpiece position) when the gripping operation is repeatedly performed in the same sequence for the same workpiece.
*7 A reference value for correcting an error in reciprocal operation which occurs during the positioning operation.
*8 Impact resistance: No malfunction occurred when the slide table was tested with a drop tester in both an axial direction and a perpendicular direction to the lead screw. (Test was performed with the gripper in the initial state.) Vibration resistance: No malfunction occurred in a test ranging from 45 to 2,000 Hz. Test was performed in both an axial direction and a perpendicular direction to the lead screw. (Test was performed with the actuator in the initial state.)
*9 The power consumption (including the controller) is for when the actuator is operating. The standby power consumption when operating is for when the gripper is stopped in the set position during operation (including energy-saving mode when gripping).
*10 The maximum instantaneous power consumption (including the controller) is for when the actuator is operating. This value can be used for the selection of the power supply.

Common Cautions
*1 Range within which the finger can move when it returns to origin. Make sure the workpiece mounted on the finger does not interfere with the workpieces and equipment around the finger.
*2 Secure the motor cable so that it will not be bent repeatedly.

Precautions
- *The parameters of the stroke and the open/close speed are for both fingers.
- *The stroke and the open/close speed for one finger is 1/2 the set parameter.
- *When gripping a workpiece by the product, be sure to set to "Pushing."
- *Also, do not hit the workpiece with the finger and attachment during positioning or in the range of positioning. Otherwise, the lead screw can get caught and this may result in a malfunction. However, if the workpiece cannot be gripped when pushing (such as if the workpiece is a plastically deformed workpiece or rubber component, etc.), grip it when positioning giving consideration to the elastic force of the workpiece.
- *There is no effect on the backlash during pushing.
- *The return to origin is done by pushing. The finger position can be displaced by the effect of the backlash during positioning. This backlash displacement should be considered when setting the position.
- *See the manufacturer's catalog for product information other than the above.
- *Product images are representative images.
