Permissible current consumption of 5 V encoders without Remote Sense depending on the cable 
length (valid for cable cross-sections of 0.5 mm

): 
 
Figure 4-8  Maximum encoder current consumption depending on the cable length 
For encoders without remote sense the permissible cable length is restricted to 100 m 
(reason: the voltage drop depends on the cable length and the encoder current).
