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.

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.
