Adaptive controller

(Note) EC series has their controller built-in themselves. See page 285 for further details on the built-in controller.

Important notes on selection

 (1) The value shown for load capacity in "Main specification" refers to the maximum value. Please refer to "Load capacity by speed and acceleration table" for further information.
(2) Radial cylinder has a built-in guide. See page 377 for details on the radial load acting on the rod.
(3) Horizontal load capacity shown assumes an operation running with an external guide.
(4) Refer "Correlation of pressing force and current limit value" for further information on pressing motion. Pressing force shown are their standard value.
(5) Safety measures may be required depending on the attachment orientation. Refer to page 379 for further details.
