Selection considerations
![]() |
(1) When the stroke is long, the maximum speed decreases due to the critical speed of the ball screw. Check the maximum speed for the desired stroke in "Stroke and maximum speed". (2) The maximum load capacity in "Main specifications" is indicated. For details, refer to "Table of load capacity by speed and acceleration". (3) When performing a pressing operation, refer to "Correlation diagram of pressing force and current limit value". The pressing force is a guideline value. For points of caution, refer to page 1-315 of the general catalog . (4) Duty ratio must be limited depending on the ambient temperature used. For details, refer to page 1-326 of the general catalog . (5) Caution is required depending on the mounting position. For details, refer to page 1-307 of the general catalog . (6) The guideline for the overhang load length is 400 mm or less in the Ma, Mb, and Mc directions (800 mm or less for double slider specifications). For the overhang load length, refer to the explanation on page 2-109 of the general catalog . (7) The center of gravity of the mounting object should be 1/2 or less of the overhang distance. Even if the overhang distance and load moment are within the allowable values, if abnormal vibrations or noise occur during operation, relax the operating conditions. (8) For ordering models and precautions when using double slider specifications, refer to page 1-293 of the general catalog . (9) When connecting RCON-EC connection specifications (ACR) to an EC connection unit (RCON-EC-4), there is a limit to the number of units that can be connected. For details, refer to page 2-798 of the general catalog . |

(Note) When performing origin return, the slider will move to the ME, so please be careful not to interfere with the surroundings.
(Note) Pay attention to the length of the mounting bolts. When using mounting screws on the back of the base, if the bolts are long, they may interfere with the internal parts, causing abnormal sliding or damage to the parts.
(Note) If you want to secure the actuator using the through-hole in the base, you will need to remove the side cover and stainless steel sheet.
(Note) For strokes of 50/100, some through-holes cannot be used. Please install the main body using the screw holes on the bottom of the base.
