Positioning IP 240
Numerical representation and ranges for input and output values
The table below provides an overview of the digit positions actually used and of the ranges for all
input and output values.
The table also shows, once again, in which cases you need binary and in which cases BCD
representation for numerical values. In the column headed ”Configuring parameter” you will find
the allocation of the data item to configuring parameter BCD/x or BCD/y.

10.4 Axis Types
The IP 240 can be used in conjunction with a linear or a rotary axis.
10.4.1 Linear Axis
When a linear axis is used, the traverse path is delimited by two end points. The maximum traver-
sing range results from the permissible actual value range of - 9,999,999 to +9,999,999
increments.
