The motion profile is changed by loading a new servo drive program into the system. The unit delivers flexible indexing and rotary positioning in welding, positioning system, medical product, automotive, aerospace, and semiconductor applications. The system combines roller pinion system technology with a bearing and gearhead. The table is supported by a cross-roller bearing rated for loads up to 1575 kN. It is capable of speeds up to 94 RPM, and can handle peak torque inputs at any time.
