Precautions when performing pressing operation

During high thrust pressing operations in high temperature environments,

Please use within the limits shown in the graph.

Adaptive Controller

(Note) The EC series has a built-in controller. For details on the built-in controller, see page 2-769 .

International Standards

Selection considerations

(1) If the stroke is long, the maximum speed will decrease due to the dangerous rotation speed of the ball screw. Check the maximum speed of the desired stroke in "Stroke and Maximum Speed".
(2) The maximum load capacity in "Main Specifications" is shown. For details, refer
　to "Table of Load Capacity by Speed and Acceleration".
(3) The radial cylinder has a built-in guide.
　For details about the radial load acting on the rod, refer to page 2-91
. (4) The horizontal load capacity is when used in conjunction with an external guide.
(5) When performing a pressing operation, refer to "Correlation diagram between pressing force and current limit value". The pressing force is a guideline value.
(6) Caution is required depending on the installation posture. For details, refer to page 1-307
. (7) When connecting the RCON-EC connection specification (ACR) to the EC connection unit (RCON-EC-4), there is a limit to the number of units that can be connected. For details, refer to page 2-798 .

Dimensions

ST: Stroke

ME: Mechanical end

SE: Stroke end

(Note) When performing a return to origin, the rod moves to the ME, so be careful not to let it interfere with the surroundings.

(Note) Pay attention to the length of the mounting bolts. When using mounting screws on the back of the base, if the bolts are long, they may interfere with the internal parts, causing abnormal sliding or damage to the parts.

(Note) The direction of the width across flats cannot be changed.
