Use
The following assignment applies to the terminals:
● Ten signals can each be assigned to connectors X122 and X132:
– Six digital inputs
– Four bidirectional digital inputs/outputs
These twelve inputs and eight inputs/outputs are used for drive control.
● For the X242 connector, four inputs and four outputs are available for the NC.
● For the X252 connector, four inputs and two outputs are available for the NC.
Cable specification at X122, X132, X242 and X252
Please note the following:
● Use flexible cables with a cable cross-section of at least 0.25 mm
2
● Ferrules are not required.
● You can use ferrules without an insulating collar in accordance with DIN 46228, Form A
long version.
● You can connect two cables each with a cross section of 0.25 mm
