Correlation diagram of pressing force and current limiting value

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) Since the feed screw does not have a rotation stopping mechanism, please add a rotation stopping mechanism such as a guide to the tip of the feed screw when using. (Doesn't move front or back without a detent mechanism to suppress rotation of the feeding screw) Floating joints shall not be used to connect the rod to the detent mechanism. Refer to page 388 for mounting method and conditions.
(2) Payload shown in the "main specification" is it's maximum value.
(3) Horizontal load capacity shown assumes an operation running with an external guide. Do not apply external force from directions other than the moving direction of the rod.
(4) Refer "Correlation of pressing force and current limit value" for further information on pressing motion. Pressing force shown are their standard value. Please see page 396 for important notes.
(5) Safety measures may be required depending on the attachment orientation. See page 379 for further details.
