To execute a linear interpolated move, specify the endpoint coordinates and the desired linear interpolation operation. The endpoint is specified as an incremental number of pulses from the current position on each axis, or the desired absolute position coordinates. Commander automatically identifies the axis with the larger feed distance as the main axis, and the other axes as the secondary axes. The main axis is supplied a pulse rate tied to the specified feed rate, while the secondary axes are supplied with a reduced pulse rate based on the interpolation calculations. 

Precision of linear interpolation

As shown in the figure on the right, linear interpolation executes an interpolation from the current coordinates to the end coordinates provided. The positional precision of a specified line during linear interpolation will be ±0.5 LSB throughout the interpolation range. 

"LSB" refers to the minimum feed unit for the system. It corresponds to the resolution of the mechanical system. (Size of the cells in the figure on the right.)

See the PCL6045BL manual, section 9.8.5 for more information.
