In order to avoid electromagnetic interference, the cable adaptation with a terminal resistor of R
0
= 120 Ω is necessary.
When connecting more than one parallel signal input to an encoder output signal (e�g� linear
motors with parallel connection to position controller, speed controller or acceleration controller)
ensure that the resulting terminal resistance of these inputs is R
0res
≈ 120 Ω.
