Acceptance of the channel-specific diameter/radius programming
DIAMCHANA:
DIAMCHAN:
Non-modal axis-specific diameter/radius programming
The non-modal axis-specific diameter/radius programming specifies the dimension type as
a diameter or radius value in the part program and synchronized actions. The modal status
of diameter/radius programming remains unchanged.
DAC:
DIC:
RAC:
RIC:
Note
With DIAMONA[<axis>] or DIAM90A[<axis>], the transverse-axis actual values are
always displayed as a diameter. This also applies to reading of actual values in the
workpiece coordinate system with MEAS, MEAW, $P_EP[x] and $AA_IW[x].
Note
During the replacement of an additional transverse axis because of a GET request, the status
of the diameter/radius programming in the other channel is accepted with
RELEASE[<axis>].
Fundamentals
Programming Manual, 09/2011, 6FC5398-1BP40-2BA0
With the DIAMCHANA[<axis>] command, the specified axis accepts the
channel status of the diameter/radius programming and is then assigned
to the channel-specific diameter/radius programming.
With the DIAMCHAN command, all axes permitted for the axis-specific
diameter programming accept the channel status of the diameter/radius
programming and are then assigned to the channel-specific diameter/
radius programming.
The DAC command sets the following dimensions to non-modal for the
specified axis:
Diameter in absolute dimensions
The DIC command sets the following dimensions to non-modal for the
specified axis:
Diameter in incremental dimensions
The RAC command sets the following dimensions to non-modal for the
specified axis:
Radius in absolute dimensions
The RIC command sets the following dimensions to non-modal for the
specified axis:
Radius in incremental dimensions
