MK_EPSILONMM

This machine constant is used for tolerance analysis [mm] when specifying
translatory positions. It is currently taken into account during circle center
point programming only, where it determines exactly how the circle’s radius
and center are to be programmed.

During the interpretation of a circle, the control reports a fault if the
programmed radius of a circle is less than this MC or if the difference
between the starting radius and the target radius is bigger than this MC. The
starting radius is the distance between the programmed center and the
starting point, and the end radius the distance between the target point and
the programmed center of the circle.

4.3.12

MK_EPSILONGRAD

This machine constant is used for tolerance analysis [grad] when specifying
rotative positions. It only affects the programming of direction−dependent
modulo 360

°

axes (see MK_ACHSENART). This is where it defines whether

the programmed traversing movement is executed or suppressed.

Example:

A rotation axis is to be positioned to +90

°

. The sign defines the direction.

Depending on whether the axis was previously at 89.5 or 90.5, it would now
have to be traversed either by half a degree or by 359.5 degrees.

MK_EPSILONGRAD intervenes by suppressing the traversing movement if
the traverse path is larger than 360

°

−MK_EPSILONGRAD in the absolute

dimension system.

4.3.13

MK_OVERRIDEMAX

This machine constant limits the override specification to this value (input
in 0.1 %).

4.3.14

MK_FEHLERRESTART

This machine constant activates the function "Wiederanlauf nach Fehler"
("Restart after error"), which allows you to restart at the point of
interruption or at a point previously defined in the program after a global
minor error (error class 3) in the program. After an error of this kind, the
program goes into standby mode which can be exited via Start (possibly
Start after G10) for restart or Stop.

Value

Meaning

0

No restart possible, global minor error leads to program termination (default).

1

Restart after error possible.

106).
