(Note) CE is compatible only with safety category compliant specifications.
Important notes on selection
 | (1) The maximum acceleration/deceleration differs depending on the load capacity. (Refer to page 4-667) The maximum speed cannot be achieved with the pulse motor at the maximum payload setting. If increase speed, the load capacity will drop. (Refer to page 4-669) (2) Positioning repeatability is applicable only when the main body temperature is constant. It will not guarantee the absolute accuracy. (3) The value of the dynamic allowable moment is the value of each axis. When the standard rated life is 5,000 km and the standard load factor is 1.5. (Refer to page 4-671 for the dynamic allowable moment.) (4) Enter "E" in the expansion I/O slot 1 and 2 of the model item if it is not used. |

*1 When placing a work on the X slider, make sure that there is a margin of 2 mm or more for the main frame.
(Note) During home return, the slider moves to the mechanical end. Pay attention to prevent contact between the slider and the surrounding.
