Meaning
Modal axis-specific diameter programming
DIAMONA:
DIAM90A:
DIAMOFA:
DIACYCOFA:
<axis>:
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.

Programming Manual, 12/2019, 6FC5398-2EP40-0BA0
Command for the activation of the independent axis-specific diameter programming
The effect of DIAMONA is independent of the programmed dimensions mode
(G90/G91 or AC/IC):
Dimensions in the diameter
● For G90, AC:
Dimensions in the diameter
● For G91, IC:
Command for the activation of the dependent axis-specific diameter programming
The effect of DIAM90A depends on the programmed dimensions mode:
Dimensions in the diameter
● For G90, AC:
Dimensions in the radius
● For G91, IC:
Command for the deactivation of the axis-specific diameter programming
Axis-specific radius programming takes effect when diameter programming is de‐
activated. The effect of DIAMOFA is independent of the programmed dimensions
mode:
● For G90, AC: Dimensions in the radius
Dimensions in the radius
● For G91, IC:
Command for the deactivation of axis-specific diameter programming during cycle
processing.
In this way, computations in the cycle can always be made in the radius. The last
G command active in this group remains active for the position indicator and the
basic block indicator.
Axis identifier of the axis for which the axis-specific diameter programming is to be
activated.
Permitted axis identifiers are as follows:
● Geometry/channel axis name
or
● Machine axis name
Range of values: The axis specified must be a known axis in the channel.
Other conditions:
● The axis must be permitted for the axis-specific diameter
programming via MD30460 $MA_BASE_FUNC‐
TION_MASK.
● Rotary axes are not permitted to serve as transverse axes.
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.
