Detailed Description
2.1 Defining a geometry axis as transverse axis
Basic logic functions: Transverse axes (P1)
8 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
With:
• MD20100, the function G96/G961/G962 is assigned to the transverse axis during power
up.
• MD20100, the channel-specific diameter programming DIAMON, DIAMOF, DIAM90,
DIAMCYCOF is assigned to the transverse axis during power up.
This axis occupies the axis-specific basic position DIAMCHANA[AX] after power up.
• MD30460 bit2 the additional enabling of the axis-specific statements DIAMONA[AX],
DIAMOFA[AX], DIAM90A[AX], DIACYCOFA[AX], DIMCHANA[AX].
Example for defining a transverse axis in the channel
MD20100 $MC_DIAMETER_AX_DEF=”X”
;the geometry axis X is the transverse axis in the
channel
Restrictions
However, only exactly one geometry axis can be defined as transverse axis per channel.
With MD30460 $MA_BASE_FUNCTION_MASK bit2=1 is only permitted for linear axes.
Channel-specific basic position after power up, RESET
The channel-specific basic position after power up or RESET or end of parts program of the
G group 29: DIAMON, DIAM90, DIAMOF, DIAMCYCOF define the
MD20150 $MC_GCODE_RESET_VALUE
and independently of
MD20110 $MC_RESET_MODE_MASK / bit0 the 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
A reference axis for G96/G961/G962 can also be assigned without application of a
transverse axis in MD20100 via SCC[AX]. For this scenario, the constant cutting speed
cannot be activated with G96. For further information refer to
