Error code Meaning
6 Impedance of encoder circuit too
H
high
Wire break between the module
and sensor
Channel not connected (open)
7 Value is above overrange.
H
Value is below underrange.

faulty
16 At least one hardware interrupt
H
could not be signaled because
too many hardware interrupts are
pending.
Remedy
Use a different encoder type or
modify the wiring, for example,
using cables with larger cross-
section
Connect the cable
