(Note) EC series has their controller built-in themselves. See page 2 771 for details of the built-in controller.

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" for further information on pressing motion. Pressing force shown are their standard value.
(4) The duty ratio must be limited according to the ambient temperature of use. Refer to page 1-326 for further details.
(5) The approximate overhang load length is 280mm or less in Ma, Mb and Mc directions. Please refer to page 2-109 for the overhang load length.
(6) The interface box is not dust-proof/drip-proof. Install it in a place where it will not be exposed to water.
(7) Requires extra care required depending on the mounting posture. Refer to page 1-307 for further details.

*1 For detailed dimensions of the interface box, please refer to "Interface box dimensions".

*2 5m actuator cable is also available as an option.

*3 The interface box relay part within the broken line is not dust-proof/drip-proof.

*4 Please ensure that the total length of the actuator cable and power I/O cable is 10m or less.

(Note) Please be careful while returning to the home position, for there is a chance of collision while having the slider returning to the M.E. position.
