Description: The distances between two reference marks are defined variably, so that the position
of the crossed reference marks can be determined accurately in linear measuring
systems with distance-coded reference marks.
The difference between two reference mark distances is entered in MD34310
$MA_ENC_MARKER_INC.
MD irrelevant for:
Incremental measuring systems
Special cases:
On linear measuring systems with distance-coded reference marks supplied by
Heidenhain,
the interval
between two reference marks is always equal to one graduation
cycle.

Description: ● Distance-coded measuring system:
REFP_STOP_AT_ABS_MARKER = 0:
At the end of the reference cycle, the position entered in MD34100 $MA_REFP_SET_POS is
approached (normal case for phase 2).
REFP_STOP_AT_ABS_MARKER = 1:
The axis is braked after detection of the second reference mark (shortening of phase
2)
● Absolute encoder:
MD34330 $MA_REFP_STOP_AT_ABS_MARKER defines the response of an axis with a valid
calibration
identifier (MD34210
$MA_ENC_REFP_STATE = 2) with G74 or when a traversing
key is actuated in JOG-REF:
REFP_STOP_AT_ABS_MARKER = 0:
Axis traverses to the position entered in MD34100 $MA_REFP_SET_POS
REFP_STOP_AT_ABS_MARKER = 1:
Axis does not traverse.
MD irrelevant for:
Incremental encoders with zero mark (standard encoders)

- 1 0.0, 0.0 0.0 0.5 3/3
Description: Using low-resolution encoders, a more continuous motion of coupled path or axis
motions can be achieved with smoothed actual values. The bigger the time constant, the
better the smoothing of actual values and the larger the overtravel.
Smoothed actual values are used for:
