P1: Transverse axes
4.2 Parameterization
MD20360 $MC_TOOL_PARAMETER_DEF_MASK
Bit

1) The function is dependent upon the settings in MD20100 $MC_DIAMETER_AX_DEF and MD30460
$MA_BASE_FUNCTION_MASK, bit 2
Behavior during manual handwheel traversing
The behavior during manual handwheel traversing (MD11346
$MN_HANDWH_TRUE_DISTANCE == 1 or 3) of a transverse axis while diameter
programming is active can be adjusted with the following machine data:
MD20624 $MC_HANDWH_CHAN_STOP_COND.Bit 15 = <value>
Bit

Displaying position values in the diameter
Position values of transverse axes are always displayed as diameter values, if:
MD27100 $MC_ABSBLOCK_FUNCTION_MASK, bit 0 = 1
Channel-specific basic position after power up, reset
The channel-specific basic position after power up or channel reset or the part program end of
G group 29 (DIAMON, DIAM90, DIAMOF, DIAMCYCOF) is defined by the machine data
MD20110 $MC_RESET_MODE_MASK.
MD20110 $MC_RESET_MODE_MASK, bit 0 = 0:
● Power-up: Basic position according to MD20150 $MC_GCODE_RESET_VALUE
● Channel reset or part program end: Basic position according to MD20150
$MC_GCODE_RESET_VALUES
MD20110 $MC_RESET_MODE_MASK, bit 0 = 1:
● After power-up: Basic position according to MD20150 $MC_GCODE_RESET_VALUE
● After channel reset or part program end: Basic position according to MD20152
$MC_GCODE_RESET_MODE
The user can set the respective desired status via an event-driven program call (ProgEvent).
If the basic position after the power-up is G96 / G961 / G962, a transverse axis must be defined
with MD20100 $MC_DIAMETER_AX_DEF, otherwise the alarm 10870 is displayed.

Value Meaning
1 When jogging around circles, the circle center point coordinate is always a radius
1)
value, see SD42690 $SC_JOG_CIRCLE_CENTRE
1 For cycle masks, the absolute values of the transverse axis are always meant as the
1)
radius.
1 Incremental values of the transverse axis for cycle masks as diameters
Value Meaning
0 Only the half path of the specified increment is traveled.
1 The specified increment is traveled completely.
