Detailed Description
2.2 Dimensional information for transverse axes
The following axis-specific modal statements can be programmed several times in a parts
program block:
• DIAMONA[Axis]: Diameter programming for G90, G91 AC and IC ON
• DIAMOFA[Axis]: Diameter programming OFF, in other words, radius programming ON
• DIAM90A[axis]: Diameter or radius programming depending on the reference mode:
– Diameter programming ON in connection with absolute dimensioning G90 and AC
– Radius programming ON in connection with incremental dimensioning G91 and IC
• DIACYCOFA[axis]: Radius programming for G90 and G91 ON , for the HMI, the last
active G code of this group remains active
• DIAMCHANA[axis]: Acceptance of diameter programming channel status
• DIAMCHAN: all axes with MD30460, bit2=1 accept the diameter programming channel
status
Axis-specific modal statements have priority over the channel setting.
Acceptance of the additional transverse axis in the channel
Due to a GET request from the parts program, the diameter programming status for an
additional transverse axis is accepted in the new channel during axis replacement using
RELEASE[axis].
Axis replacement in synchronized actions
For axis replacement in synchronized actions, a transverse axis takes the status of the axis-
specific diameter programming with it into the new channel if the following applies to the
transverse axis:
• with MD30460, bit2=1 axis-specific diameter programming is permitted.
• it is not subordinated to the channel-specific diameter programming in the releasing
The active dimension can be queried via the system variable $AA_DIAM_STAT[AX].
Axis replacement via axis container rotation
By rotating the axis container, the assignment of a channel axis can change to assignment of
a machine axis. The current diameter programming status is retained however for the
channel axis after the rotation. This also applies to the current channel status and axis
status, because the status is the same for all axes of the axis container at the time of the
machine data "putting into effect" the status from MD30460 $MA_BASE_FUNCTION_MASK.
Initial setting
The following machine data is used to parameterize the initial setting:
MD20150 $MC_GCODE_RESET_VALUES [28] (initial setting of the G groups)
and independently of MD20110 $MC_RESET_MODE_MASK for bit0 the
MD20152 $MC_GCODE_RESET_MODE
10
channel.
