Signal connection

Design of the signal connector
The signal connector of the 1FK2 is an M17 round connector.
The connector pin assignment is as follows.
The signal connectors can be rotated within a certain range.

Connecting to a converter

8.3.4.1

Selecting and connecting the cables

● Use prefabricated MOTION-CONNECT cables from SIEMENS or shielded connecting
cables.
● The prefabricated MOTION-CONNECT cables reduce installation costs and increase the
operational reliability
Note
The cable shielding, made up of as many strands as possible, must have a high electrical
conductivity. Braided shields made of copper or aluminum are well suited.
When connecting, comply with the following:
● Connect the shield to the converter.
● Keep the unshielded cable ends as short as possible.
● To ensure good discharging of high-frequency currents, provide contacting over a large
surface area.
