Siemens SINUMERIK 828D Commissioning Manual page 457

Normally, assign the following frames for a zero offset:
MD10616 $MN_MAPPED_FRAME_MASK
Bit 0 = 1
Bit 12 = 1
Bit 13 = 1
With the following machine data, specify the connection of the axes that should have the same
value in the zero offset over all channels:
MD32075 $MA_MAPPED_FRAME[AXn]
Example:
Axis AX2 = Z1 (Z-axis in the first channel)
Axis AX6 = Z3 (motion axis of the counterspindle)
Axis AX11 = Z2 (Z-axis in the second channel)
MD32075 $MA_MAPPED_FRAME[AX6] = "AX6"
MD32075 $MA_MAPPED_FRAME[AX11] = "AX2"
The motion axis of the counterspindle is connected with itself (Z3 = Z3). The two Z-axes of the
channels are connected (Z2 = Z1). You only need to create the connection of the axes in one
direction.
