The EMC depends on the configuration of the customer s control panel and the relationship with other electrical equipment and wiring. Therefore conformity to the EMC directive cannot be certified for SMC components incorporated into the customer s equipment under actual operating conditions. As a result it is necessary for the customer to verify conformity to the EMC directive for the machinery and equipment as a whole. wfor the servo motor (24 VDC) specification, EMC compliance was tested by installing a noise filter set (LEC-NFA). Refer to the catalog CAT.ES-87 for the noise filter set. Refer to the LECA Operation Manual for installation. [UL-compliant products] When conformity to UL is required, the electric actuator and controller/driver should be used with a UL13 Class 2 power supply. Applicable stroke table Stroke Model (mm) Standard Manufacturable stroke range [mm] LEFS16 to 4 LEFS25 to 6 LEFS32 to 8 LEFS4 to Strokes are manufacturable in 1 mm increments. Refer to the manufacturable stroke range. However, strokes other than those shown above are produced as special orders. Consult with SMC for lead times and prices. The actuator and controller/driver are sold as a package. Confirm that the combination of the controller/driver and the actuator is correct. <Check the following before use.> q Check the actuator label for model number.

Note 4) Impact resistance: No malfunction occurred when the actuator was tested with a drop tester in both an axial direction and aperpendicular 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 to 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.) Note 5) The power consumption (including the driver) is for when the actuator is operating. Note 6) The standby power consumption when operating (including the driver) is for when the actuator is stopped in the set position during the operation. Note 7) The maximum instantaneous power consumption (including the driver) is for when the actuator is operating. Note 8) Only when motor option With lock is selected.
