Behavior during handwheel travel
Behavior during handwheel travel (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
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 / reset or the end of the parts program of
G function group 29 (DIAMON, DIAM90, DIAMOF, DIAMCYCOF) is defined through machine
data:
● MD20150 $MC_GCODE_RESET_VALUE
Or (for MD20110 $MC_RESET_MODE_MASK bit 0 = 1):
● MD20152 $MC_GCODE_RESET_MODE
The user can set the respective desired status via an event-controlled program call (prog-
event).
If G96/G961/G962 is the basic position after power up, a transverse axis must be defined using
MD20100 $MC_DIAMETER_AX_DEF, otherwise the alarm message 10870 is output.
Reference axis for G96/G961/G962 retained:
MD20110 $MC_RESET_MODE_MASK, bit 18=1 for reset or end of parts program
MD20112 $MC_START_MODE_MASK, bit 18=1 for start of parts program

Value Meaning
1 Display of remaining path in WCS always as a radius
For all transverse axes, with MD11346 $MN_HANDWH_TRUE_DISTANCE==1
0
● half of the path of the specified handwheel increment is traveled, if channel-
specific or axis-specific diameter programming is active for this axis.
1
● half of the path of the specified handwheel increment is always traveled.
1 When jogging around circles, the circle center point coordinate is always a radius
value, see SD42690 $SC_JOG_CIRCLE_CENTRE
1 For cycle masks, the absolute values of the transverse axis are in the radius.
Value Meaning
0 Only the half path of the specified increment is traveled.
1 The specified increment is traveled completely.
