*
Short-circuit of the encoder supply to ground and/or of the input signal to the encoder supply of a channel can have a
temporary effect on other channels (duration < 0.5 s). This means the short-circuit diagnostics can also be reported for
unaffected channels and/or the measured value can be affected temporarily.
** In case of activated smoothing the module calculates the measured values across several module cycles. The module
only generates the wire break diagnosis if the smoothed measured value is stable. After the wire break has been elimi-
nated, the module supplies stable measured values again depending on the set smoothing level.
