The assignment of the area of the parameter field, in which the internal data
of the NC computer is stored, is specified in the following. The specified digits
correspond to the parameter numbers under which the variables are
addressed. Axis−related values are always entered in the sequence in which
they are defined in the machine constant MK_APPLACHSIDX.
Meaning of the units in the following tables:
Unit Meaning
Inc Increments
°
Degree
Unit Translative path input unit, machine constant−dependent (default = mm)
mm Millimeter
m Meter
h Hour
min Minute
s Second
ms Millisecond
GIT Coarse interpolation cycle
MC Unit is dependent on the machine constants
% The parameter is specified in percent
−−− The parameter has no unit
With some parameters, the unit is dependent on whether the parameter
belongs to a linear axis or a rotation axis. In the case of linear axes, the input
unit is also dependent on the value in the machine constants
MK_METRISCH, MK_CONST_REL_MM and MK_CONST_REL_INCH. The
following enhanced table applies to these parameters.
Unit Meaning with linear axes Meaning with rotation axes
mm * Input unit Degree
mm/min * Input units/minute Revolutions/minute
m/s 2 * Meter/second 2 Revolutions/second 2
Inc/mm * Increments/input unit Increments/degree
A cross in field "Sync" indicates that the access to the corresponding
parameter is time synchronized, i.e. that the contents of the parameter in a
NC program is only read when the block was executed before. The further
interpretation of the NC program is also stopped until this has happened.
Index Meaning Sync Unit
0 ... 15 NC actual position of the axes in reference to the
current coordinate system x mm *
16 ... 31 Total of modal actual position and NC actual position of
the axes (P160ff+P0ff) x mm *
32 ... 47 NC target position of the axes in reference to the
current coordinate system x mm *
64 ... 79 Zero point offset of coordinate system S0 x mm *
80 ... 95 Zero point offset of coordinate system Sn (−> P586) from
channel N x mm *
96 ... 111 Zero point offset of coordinate system Sn (−> P554) from
channel 0 x mm *
