2012 SMC Corporation All Rights Reserved Electric Slide Table/Compact Type Series LES C £ cWus CROHS Compared with the LESH, Workpiece mounting surface height: Symmetrical type Compact type * By reducing weight of the moving parts >Max. pushing force: 180 N •Possible to reduce cycle time ►Positioning repeatability: ±0.05 mm Max speed: 4Q0 mm/s ► Step data input type • Input using controller setting • Control panel setting ► Pulse input type Series LECPA

Electric Slide Table Selection Procedure Check the work load-speed. Check the cycle time Selection Example Check the work load-speed. <Speed-Work load graph> (Page 3) Select the target model based on the workpiece mass and speed with reference to the <Speed-Work load graph>. Selection example) The LES16DJ-50 is temporarily selected based on the graph shown on the right side. Check the cycle time. It is possible to approximately calculate the cycle time by using method 1, however, if more detailed cycle time is required, use method 2. Method 1: Check the cycle time graph. (Page 4) Method 2: Calculation...

Electric Slide Table Selection Procedure Check the required force. Check the set value of pushing force. Selection Example • Pushing force: 90 [N] •Mounting orientation: Vertical upward • Workpiece mass: 1 [kg] "Pushing time + Operation (A): 1.5 seconds • Speed: 100 [mm/s] •All cycle time (B): 6 seconds Check the required force. Table Weight Calculate the approximate required force for pushing operation. Selection example) "Pushing force: 90 [N] Therefore, the approximate required force Select the target model based on the approximate required force with reference to the specifications (Pages...
