The following applies when using absolute encoders:
In Slave-mode the clock signal is generated by an external process and is read in by the
SMX 100 module together with the data signal. This type of reading causes a beat which results
in a reading fault of the following magnitude:
F = (reading time of encoder by external system [ms] / 8 [ms] ) * 100 %
The size of the resulting reading fault F must be taken into account when determining the
thresholds in the applied monitoring functions, because this fault cannot be compensated!
