Oversea specification

Important notes on selection

(1) Maximum speed drops when the stroke length increase, preventing it from reaching the critical revolution value of the ball screws. Use the "Stroke and Max.speed" to check the maximum speed at the stroke you desire.
(2) The value shown for load capacity in "Main specification" refers to the maximum value. When enabling the power saving setting, the main specifications will change. For details, refer to "Payload table by speed/acceleration".
(3) Refer "Correlation of pressing force and current limit value" if you may need to operate pressing motion. Pressing force shown are their standard value. Refer page 1- 315 for important points to be taken note of.
(4) The duty ratio must be limited according to the ambient temperature of use.
Refer to page 1-326 for further details.
(5) Requires extra care required depending on the mounting posture.
Refer to page 1-307 for further details.
(6) Vertical installation is not available for lead S and lead H.
(7) Push motion is not available for lead S.
(8) The approximate overhang load length is 500mm or less in Ma, Mb and Mc directions. Please refer to page 2-109 for the overhang load length.
(9) The center of gravity of the attached object should be less than 1/2 of the overhang distance. Even if the overhang distance and load moment are within the allowable values, if abnormal vibration or noise occurs during operation, loosen the operating conditions before use.
