Power supply

1.6.1 Max. load capacity in dependence of voltage supply

Max. load capacity at +5 V:
The specified current is reduced by the current taken from the second interface (see application
manual Chapter 6.10).

1.6.2 Line length

The maximum line length results from the voltage drop of the supply line. The value is
calculated as follows:
KEB encoder cable resistance R: 0,072 Ω/m
