This document provides specifications for the RCP2 ROBO Cylinder rotary actuator. It includes: 1) Graphs showing how output torque and allowable moment of inertia decrease as rotational speed increases. 2) Details that the rated acceleration is 0.2G and deceleration ratios of 1/30 and 1/45 are available. 3) A list of compatible controllers that can operate the actuator, including easy to use solenoid valve types and more advanced positioning and programmable controllers.

RCP2-RTCS/RTCSL ROBO Cylinder Rotary Small Flat Type 72mm Width Pulse Motor
* 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 0.2G.

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.

Note:
* In the 2D drawing on the left,
the shaded area indicates the
rotating part.
Note:
The position in the 2D 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.
