Transformation type
● MD24100 $MC_TRAFO_TYPE_1 = 256 (transformation TRANSMIT with a rotary or linear
axis)
Offset relative to the zero position of the rotary axis
● MD24900 $MC_TRANSMIT_ROT_AX_OFFSET_1 = 0
Sign of rotary axis
● MD24910 $MC_TRANSMIT_ROT_SIGN_IS_PLUS_1 = 0
Basic offset of the tool zero relative to the geometry axes while TRANSMIT is active
● MD24920 $MC_TRANSMIT_BASE_TOOL_1 [ 0 ] = 0.0 (offset relative to 1st TrafoGeoAxis)
● MD24920 $MC_TRANSMIT_BASE_TOOL_1 [ 1 ] = 0.0 (offset relative to 2nd TrafoGeoAxis)
● MD24920 $MC_TRANSMIT_BASE_TOOL_1 [ 2 ] = 0.0 (offset relative to 3rd TrafoGeoAxis)
TRANSMIT input axes
● MD24110 $MC_TRAFO_AXES_IN_1[ 0 ] = 1 (1st channel axis XC, perpendicular to the
rotary axis)
● MD24110 $MC_TRAFO_AXES_IN_1[ 1 ] = 3 (3rd channel axis CC, rotary axis)
● MD24110 $MC_TRAFO_AXES_IN_1[ 2 ] = 2 (2nd channel axis ZC, parallel to the rotary
axis)
Modulo conversion for rotary axis
● MD30300 $MA_ROT_IS_MODULO[ 0 ] = 0 (1st machine axis: spindle/rotary axis)
● MD30300 $MA_ROT_IS_MODULO[ 1 ] = 0 (2nd machine axis: linear axis)
● MD30300 $MA_ROT_IS_MODULO[ 2 ] = 0 (3rd machine axis: linear axis)
● MD30300 $MA_ROT_IS_MODULO[ 3 ] = 1 (4th machine axis: spindle)
