Important notes on selection

(1) The belt type may generate vibration and noise during low-speed operation, so it is recommended to use it at a moving speed of 100 mm/s or more.
(2) The payload capacity indicated in the "Main specifications" is the maximum value. Please refer to "Load capacity by speed and acceleration table" for further information.
(3) Pressing motion can't be carried out as well.
(4) Requires extra care required depending on the mounting posture.
Refer to page 1-307 for further details.
(5) The approximate overhang load length is 320mm or less in Ma, Mb and Mc directions. Please refer to page 2-109 for the overhang load length.
(6) 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.
(7) When connecting the RCON-EC connection specification (ACR) to the EC connection unit (RCON-EC-4), the number of connections that can be made is limited. Refer to page 2-798 for further details.
