Use the Lexium P robot for ceiling mounting. For special applications with an angularly suspended robot system, contact your local Schneider Electric service representative.
oDelta-3 robots of the Lexium P reach their highest level of performance and accuracy in the center of the working space.
oPosition the robot to locate the movements to be executed as closely as possible to the center of the working space.
oWhen determining the suspension height of the robot, observe the overall height of the gripper (suction cup or other product pickups).
oFor the design of the robot frame, account for possible varying gripper heights. Design the robot suspension in a height-adjustable manner.
The precision of the robot in the application is also determined by the frame. Deformations of the frame cause imprecisions on the Tool Center Point (TCP).
General Requirements Regarding the Frame
The frame must not only withstand the constant forces and torques stated below, but also have sufficient stiffness so that the deformations and vibrations which occur do not lead to any major deviations on the TCP. Ensure a sufficient transverse bracing in the frame.
Note the forces and torques to be taken up by the frame during normal operation:
|
Parameter |
Value |
|---|---|
|
Static load |
approximately 1.2 kN (270 lbf) |
|
Dynamic load |
approximately 1.4 kN (315 lbf) in any direction |
|
Dynamic torque |
approximately 2000 Nm (17701 lbf-in) |
Fasten the robot with three screws of property class 8.8 or greater, or A2-70 or greater.
For further information, refer to the respective dimensional drawing in Mechanical and Electrical Data.
NOTE: The configuration of the robot mechanics, the TCP velocity, as well as the additional payload have an effect on the total energy, which can potentially cause damage.

CRUSHING, SHEARING, CUTTING AND IMPACT INJURY |
|
oThe robot must be operated only within an enclosure. oOpen or enter the enclosure for cleaning and maintenance purposes only. oDesign the enclosure to withstand an impact from the robot and to resist ejected parts from escaping the zone of operation. oDesign the enclosure to safely deactivate the robot as soon as a person enters the zone of operation of the robot. oAll barriers, protective doors, contact mats, light barriers, and other protective equipment, must be configured correctly and enabled whenever the robot mechanics are under power. oDefine the clearance distance to the zone of operation of the robot so the operational staff do not have access to, nor can be enclosed in, the robot mechanics zone of operation. oDesign the enclosure to account for the maximum possible travel paths of the robot; that is, the maximum path until the hardware safety system limits as well as the additional run-on paths, in case of a power interruption. |

Failure to follow these instructions can result in death, serious injury, or equipment damage. |
For further information about travel path and power loss, refer to Run-on Motions of the Robot for Risk Analysis.
Interference Contours in the Enclosure
When designing the enclosure, ensure that the upper and lower arms of the robot will have sufficient freedom of movement. Take into account the required space for the movement of the respective robot type and associated equipment.
The following table presents the type of the mounting surface and space in which the robot must be operated.

1 Interference area
VRKP••••WF / VRKP••••NF:
1 Interference area
VRKP••••WD / VRKP••••NO / VRKP••••CW:
– No interference area
NOTE: For detailed information about the interference areas caused by upper and lower arm movements, refer to the 3D-CAD data on the Schneider Electric homepage (www.schneider-electric.com) or contact your local Schneider Electric service representative.
