Basic performance: Accuracy of continuous path operation

The precise continuity of micro interpolation is the essence of motion control!

Continuous path motion is a fundamental performance requirement for motion controllers, and in precision motion control, it is a crucial point that can be considered its essence. It can be rephrased as the accurate continuity of multi-axis interpolation. Accurate continuous interpolation means "no positional error; the trajectory is precise" and "no velocity error; the speed and time are as specified." Fine and high-precision movements consist of a series of very small vectors. In processes such as machining, polishing, and winding, it is necessary to accurately maintain a large number of small interpolations continuously. The operation (processing) time T for one interpolation is determined by the feed speed F and the interpolation length L, where T = L/F. There is a limit to how small this time can be, beyond which the motion controller's control cannot keep up. This is why the minimum time for accurately continuous processing of small interpolations serves as a performance indicator for motion controllers. Techno's motion controllers can achieve continuous interpolation with a control cycle as short as 125 μsec. Accurate speed and smooth continuity are directly linked to the precision of operations and processing, significantly impacting work quality. For more details, please contact us.
