The 11-LEJS is the clean room version of SMC's LEJS ball screw slider. A built-in vacuum port is used to draw off particles generated by the ball screw and guide to achieve the ISO Class 4 standard. This model is fitted with an AC servo motor with incremental or absolute encoder. Optional drivers include pulse input and various communication protocols including Ethernet.
Catalog: Electric Actuator L : Stroke [mm] V : Speed [mm/s] a1: Acceleration [mm/s2] a2: Deceleration [mm/s2] T1 and T3 can be obtained by the following equation. T1 = V/a1 = 300/3000 = 0.1 [s], T1 = V/a1 [s] T3 = V/a2 [s] T3 = V/a2 = 300/3000 = 0.1 [s] The acceleration and deceleration values have upper limits depending on the workpiece mass and the duty ratio.

T2 = T1 T2 T3 T4 200 0.5 300 (0.1 + 0.1) 300 = L : Stroke [mm] (Operating condition) V : Speed [mm/s] (Operating condition) a1: Acceleration [mm/s2] (Operating condition) a2: Deceleration [mm/s2] (Operating condition) T1 = V/a1 [s] T3 = V/a2 [s] = 0.57 [s] T4 = 0.05 [s] T2: Constant speed time can be found from the following equation.
T1 = V/a1 = 300/5000 = 0.06 [s], T3 = V/a2 = 300/5000 = 0.06 [s] T2 = = = 0.94 [s] L 0.5 V (T1 + T3) V 300 0.5 300 (0.06 + 0.06) 300 T4 = 0.05 [s] Therefore, the cycle time can be obtained as follows.
