Encoder cable length

Allowed encoder cable length for
5 V encoder systems without
Sense function
Allowed encoder cable length for
5 V encoder systems with Sense
function
Allowed encoder cable length for
12 V encoder systems
Use lines with the same line cross section for encoder supply.
If the encoder system used does not support the Sense function, the maxi‐
mum possible cable length results from the diagram below.
I [mA] Encoder current consumption
l [m] Cable length
Line cross sections
0.5 mm 2 ; 1.0 mm 2
Fig. 7-14: Maximum allowed encoder cable lengths for 5 V encoder systems
without Sense connection depending on line cross section
75 m at most; (exception: 40 m at most for IndraDyn S MSM motors)
(Besides, the maximum allowed cable lengths depend on the motor size. See
documentation of motor used.)
The cross section of the supply voltage lines has to be at least 0.5 mm
Requirements:
● The cross section of the supply voltage lines is at least 0.5 mm
● The minimum allowed supply voltage at the encoder is 10 V
