The figure below gives a rough overview of when to use the nominal position
value filters.
The nominal position value filters (MP1200) function in all operating modes
(even in rapid traverse). For RIGID TAPPING (Cycle 17), the nominal position
value filter is automatically switched off.
If the machine dynamics are adapted via a nominal position value filter, the
iTNC always maintains
 the tolerance
• from MP1202.0 (at the machining feed rate)
• from MP1202.1 (at rapid traverse)
• from the tolerance given in Cycle 32 – mode 0 (HSC finishing filter)
• from the tolerance given in Cycle 32 – mode 1 (HSC roughing filter).
Here the limit frequency is automatically lowered so that faster
machining results for larger tolerances.
 the axis-specific jerk at corners (MP1230.x, MP1231.x, MP1232.x and
MP1233.x, MP1250.x factor from MP123x.x for rapid traverse) depending
on the filter type used
 the axis-specific jerk at curvature transitions (MP1240.x, MP1241.x,
MP1242.x and MP1243.x) depending on the filter type used
 the axis-specific acceleration (MP1060.x)
 the path acceleration (MP1061)
 the radial acceleration (MP1070.x)
 the tolerance at curvature changes.
