Delivery performance and energy efficiency
Robot feeds electricity back into the grid
Yaskawa came to Schweissen & Schneiden with the entire spectrum of robot-based welding. This year, the focus was on turnkey systems from the company's own European system construction. One technical highlight is the current solution for regenerating robot braking energy. An eye-catcher on the stand was a Motoman GP180 handling robot, which holds a monitor on its flange - and shows in real time how much energy it is currently saving during operation.
This is made possible by a technical solution for feeding robot braking energy back into the power grid - as standard and without additional hardware. All larger Motoman robots in the series with a payload of 35 kilograms or more and with the current YRC1000 robot controller can convert kinetic energy from downward and sideways movements directly into 400 volts alternating current at 50 hertz and feed it back into the grid. This significantly reduces the robot's energy requirements depending on the movement pattern.
The Motoman GP180 is mounted on a TSL-2000SY robot track. Like a welding cell with four robots, this is representative of welding systems of all sizes that Yaskawa has been planning and implementing in Allershausen near Munich for almost four decades.
