Siemens PPU 26x.3 series Manual page 85

Use
The following assignment applies to the terminals:
● Ten signals can each be assigned to X122 and X132:
– Six digital inputs
– Four bidirectional digital inputs/outputs
The following twelve inputs and eight inputs/outputs are used for drive control:
● At terminal X242, four inputs and four outputs are available for the NC.
● At terminal X252, four inputs and two outputs are available for the NC.
Note
Terminals MEXT1 ... MEXT4 must be connected for the digital inputs/outputs to function.
● Connect the incorporated ground reference of the digital inputs.
● Connect a jumper to terminal M on plug connector X1.
P24EXT (P1, P3) must also be connected so that the outputs function. An external supply can
also be connected here, or a jumper can be connected to terminal P at X1. This removes the
galvanic isolation for these digital inputs.
An open input is interpreted as "low".
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
● 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
