The values shown below are allowable values of the actuator body. Do not use the actuator so that it exceeds these specification ranges. Model Selection Series LEFB These graphs are reference examples of when an SMC standard AC servo motor is mounted. Determine the duty ratio after taking into account the load factor of the AC servo motor or driver to be used. The values show the specifications with a standard SMC motor used. Please use this as a guide. 10 LEYG LEY LEJS LEFB LEFS Model Selection
