Allowed encoder cable lengths
Selecting wire cross sections
Note: The current consumption of the connected encoder systems
generates a voltage drop due to the resistively ( dependent
upon the wire cross sections and lengths) of the wire. This
reduces the signal at the encoder input.
To compensate the voltage drop, the DKC can inuence the
encoder power source. Using a voltage sensor, the available
voltage at the encoder is known.
 For a given wire length and encoder current consumption, a minimum
cross section becomes necessary. This relationship is illustrated
below.
