(1) The RCP2 ROBO Cylinder rotary actuator uses a pulse motor with varying output torque and allowable moment of inertia based on rotational speed. (2) It can rotate 330 or 360 degrees depending on the model, with a maximum rated acceleration of 0.3G. (3) The document provides specifications, diagrams, compatible controller options and other details about the actuator.

* See page Pre-35 for an explanation of the naming convention.
(1) The output torque decreases as the rotational speed increases.
Check the output torque graph on the right to see whether the speed required for your desired motion is
supported.
(2) The allowable moment of inertia of the rotated work piece varies with the rotational speed.
Check the Allowable Moment of Inertia graph on the right to see if the moment of inertia required for your desired
motion is within the allowable range.
(3) The rated acceleration while moving is 0.3G.

■ Speed vs. Load Capacity
Due to the characteristics of the Pulse motor, the RCP2 series'
load capacity decreases at high speeds. In the table below, check
if your desired speed and load capacity are supported.

Dimensions
* The bend radius R of the cable is the same as
other models.
Note:
The position in the drawing on the left is the
home position.
When homing, the actuator rotates to the left
past the home position by 1 degree. Therefore
please watch for any interference with the
surrounding objects.
The range of motion is 330 degrees clockwise,
as viewed from above.
