Programming Manual, 01/2015, 6FC5398-1BP40-5BA2
Explanation
Checks whether the ge‐
ometry axes 1 to 3
specified as parame‐
ters are present in ac‐
cordance with machine
data MD20050
$MC_AXCONF_GEO‐
AX_ASSIGN_TAB
Converts spindle num‐
ber into axis identifier
Converts axis identifier
into spindle number
Calculates the remain‐
ing modulo values from
the entered axis posi‐
tion
If the specified axis is
not a modulo axis, the
axis position is returned
unchanged.
Determines whether
the position setpoint of
an axis is located in a
window at a predefined
reference position
