This helps ensure that working environments stay safe for humans without compromising productivity. Safety Motion uses two optical sensors, one at the top and one at the bottom of the cell, to detect an approaching operator and control the speed of the robot accordingly. The sensors create virtual safe zones that trigger an incremental reduction in the speed of the robot to safe levels depending on the distance of the operator. When the operator reaches the closest zone, the robot reduces its motor torque and slows down sufficiently to allow the operator to safely interact with it, or stops entirely. As soon as the operator leaves, the robot automatically starts running at normal speed again, minimizing stoppage time. The controller’s footprint is 12.5 x 14 inches with a height of 3.69 inches, which makes it quite small for a unit in the 3 kW output class, and helps save space on the factory floor. Optional accessories include a teaching pendant with a large, 7.5-inch color touchscreen, a mini pendant with a 128 x 64 pixel LCD display, up to two additional axes and conveyor tracking. The company’s Wincaps III 3-D simulation software allows offline programming and remote monitoring of robot operation.
