Perform an adjustment:
 Use suitable NC program.
The TNCopt software from HEIDENHAIN features the "FF_100_[axis].h" NC
programs for feedforward adjustment.
 Modify MP_axPathJerk until the following error s-diff is reduced to a few
µm (usually about 5 µm).
Step 2: Set the transition jerk (MP_axTransJerk)
Basic settings:
 Use the advanced HSC filter:
MP_shape = AdvancedHSC
 Define HSC mode (Cycle 32):
MP_hscMode = Smoothing
 Set a very low path jerk value for the measurement because the path jerk
and transition jerk overlap:
MP_axPathJerk = 5
 Set a high value for the contour tolerance:
MP_pathTolerance(Hi) = 3
 Apply the other basic settings from Step 1
Perform an adjustment:
 Observe the following error s-diff during the direction reversal
