Function
In addition to channel-specific diameter programming, there is also the axis-specific
diameter-programming function, which enables you to specify and display dimensions for
one or more axes as diameter values.
Dimensions can also be displayed simultaneously for several axes assigned to one channel.
After powerup of
• DIAMON[axis], the dimensions for the specified axis are given as a diameter value
• DIAM90[axis], the dimensions for the specified axis are given as a diameter value (in the
• DIAMON[axis] or DIAM90[axis], the transverse-axis actual values will always be
Machine manufacturer
By means of machine data which is configurable by the machine manufacturer, both axis-
specific modal diameter programming and action-based diameter programming can be
enabled. Please refer to the machine manufacturer's instructions.
