Accuracy Gain From Linear Encoders

If the position of a machine tool’s axis is measured using a rotary encoder, then potentially the ballscrew is being asked to perform two contradictory functions. The ballscrew both drives the axis into position and indicates that position—because the ballscrew lies in between the encoder and the moving element of the machine. Control technology supplier Heidenhain calls this “semiclosed-loop” operation.
