Configuration of
the nominal
position value
filters as of NCK
software version
597 110-05
As of NCK software version 597 110-05 (milestone 5), the MANUALplus 620
provides new machine parameters for configuring the nominal position value
filters:
Global setting of the nominal position value filters via System / CfgFilter
Two filters are located before the position control loop to prevent the machine
from oscillating:
 MP_defaultPosition is effective for linear axes, without TCPM also for
rotary axes.
 MP_defaultManualOrder defines the order of the mean-value filter for the
Manual operating modes.
Use MP_shape to specify the form of nominal position value filter and enter
the filter's limit frequency in MP_frequency. The MANUALplus 620 calculates
the filter order automatically.
The MP_hscMode parameter affects only HSC filters (not advanced HSC
filters) and specifies the HSC mode (roughing or finishing).
The parameters are globally effective for all axes unless you overwrite the
defined default value with the axis-specific filter parameter MP_axisPosition:
Axis-specific setting of the nominal position value filters:
 MP_axisPosition is effective for specific linear axes, and for rotary axes if
TCPM is deactivated.
 MP_manualFilterOrder defines the order of the mean-value filter for
specific axes in the Manual operating modes.
When you define an axis-specific filter, the global setting from System /
CfgFilter is overwritten for the specified axis.
The smoothing function of the nominal position value filters causes contour
errors. The velocity profile is adjusted by the look-ahead function so that the
contour error does not exceed the given tolerance (see "Look-ahead" on page
825).
