Maximum Payload

Description

The rated payload of the Robot Arm depends on the center of gravity offset of the payload, see Figure Mechanical Interface

The center of gravity offset is defined as the distance from the center of the tool flange to the center of gravity of the attached payload.

When computing the payload mass in a pick and place application, for example, consider both the gripper and object handled by the gripper.

 

UR10e10 kg / 12.5kg

You can verify the payload capacity of the robot by checking the label on the robot arm, as illustrated below.

  • The robot may have reduced acceleration capability if the payload center of gravity is exceeding the workspace of 1300mm with payloads above 10kg.

  • The robot may have reduced acceleration capability if a payload larger than 10kg is extended horizontally away from the elbow joint.

  • The robot can accommodate a long center of gravity offset, if the payload is placed below the tool flange, as is often the case in palletizing applications.

Payload Inertia

The robot can be used with high inertia payloads. The control software automatically adjusts accelerations, if you correctly enter the following in PolyScope (see:Set Payload ):

  • Payload mass
  • Center of gravity
  • Inertia

You can use the URSim to evaluate the accelerations and cycle times of the robot motions with a specific payload.
