When parameter AIH (No.7057#1) is set to “1”with inch input and millimeter output during AI contour
control / AI nano contour control mode, CNC does the following inch/metric conversion before executing the
acceleration/deceleration before interpolation. By this method, CNC controls the acceleration/deceleration so
that the time constant of acceleration /deceleration becomes the same as that of millimeter input.

AIH At inch input and millimeter output, the feedrate control of AI contour control / AI nano
contour control mode :
0 : Feedrate is calculated with 1 inch = 1 deg.
1 : Feedrate is calculated with 1 mm = 1 deg.
(The time constant of rotation axis becomes the same as that of linear axis.)
