For the LMS10x the outside diameter of the common cable must be a maximum of 9 mm
due to the PG7 cable entry.
Important If you use flexible connecting cables with stranded wire to connect to the terminals on the
LMS10x/LMS12x/LMS173, you must not use any ferrules.
6.3.3 Boundary conditions for the data interfaces
The table below shows the recommended maximum length of cable as a function of the
data transmission rate selected.
Important Use screened cable (twisted-pair) with at least 0.25 mm².
To prevent interference, do not lay data cable in parallel with power supply and motor
cables over a long run, e.g. in cable ducts.
