6 Cable lengths diagram
Cable lengths diagram for determining the required cable cross-sections in relation to the cable length and the
sum of the drive rated currents.
6.1 Formulaforcalculatingthecablecross-section
ρ x 2 x L x I
A =
U
A = Cable cross-section, A / mm²
ρ=Specicresistanceofelectriccables,ρ=0.0175(Ω*mm²)/m
2 x L = 2 x line length, L /m (outward and return line)
I = Sum of the rated currents of the connected drives, I / A
U = Max. voltage drop, U = 2.5 V
Note: Observe permitted current outputs, see Technical data.
