F2: Multi-axis transformations
1.2 5-axis transformation
Assignment of direction of rotation
The sign interpretation setting for a rotary axis is stored in the sign machine data for 5-axis
transformation.
MD24520 $MC_TRAFO5_ROT_SIGN_IS_PLUS_1[n] (sign of rotary axis 1/2/3 for 5-axis
transformation 1)
MD24620 $MC_TRAFO5_ROT_SIGN_IS_PLUS_2[n] (sign of rotary axis 1/2/3 for 5-axis
transformation 2)
Transformation types
Ten transformation types per channel can be configured in the following machine data:
MD24100 $MC_TRAFO_TYPE_1 ...MD24480 $MC_TRAFO_TYPE_10 (definition of
transformation 1 in channel ... definition of transformation 10 in channel)
Of these eight types, a maximum of two may be 5-axis transformations.
Activation
Activation of the 5-axis transformation is described in the section "Activation and Application
of 3- to 5-axis Transformation".
