Axis interchange for leading axes (gantry)

A closed gantry grouping is treated regarding its axes always as a unit regarding axis

interchange. This is the reason why for an axis interchange of the leading axis, an axis

interchange is simultaneously made for all synchronous axes of the gantry grouping. In

addition to the preconditions for the leading axis described in the previous chapters, the

appropriate preconditions must also be fulfilled for all synchronous axes of the gantry

Axial machine data

For an axis interchange, the following axial machine data must be set the same for all axes

of a closed gantry group:

● MD30460 $MA_BASE_FUNCTION_MASK, Bit 4 (control executing components)

● MD30460 $MA_BASE_FUNCTION_MASK, Bit 5 (assignment to components)

Axial NC/PLC interface signals

Within the scope of the axis interchange function, the following axial NC/PLC interface

signals always have the same values for all axes of a closed gantry grouping:

● DB31, ... DBX63.0 (reset executed)

● DB31, ... DBX63.1 (PLC controlled axis)

● DB31, ... DBX63.2 (axis stop active)

Axial system variable

Within the scope of the axis interchange function, the following axial system variables always

have the same values for all axes of a closed gantry group:

● $AA_AXCHANGE_TYP (axis type regarding axis interchange)

● $AA_AXCHANGE_STAT (axis status regarding axis interchange)

● $AA_SNGLAX_STAT (axis type of the individual axis)

Up to 10 mode groups are available for SINUMERIK 840D sl.

Only 1 mode group is available for SINUMERIK 828D.
