Tolerant encoder monitoring

The tolerant encoder monitoring offers the following expanded functionality regarding the
evaluation of encoder signals:
● Encoder track monitoring (Page 334)
● Zero mark tolerance (Page 335) (also for other sensor modules)
● Freeze speed raw value (Page 336)
● Adjustable hardware filter (Page 337)
● Edge evaluation of the zero mark (Page 338)
● Pole position adaptation (Page 339)
● Pulse number correction for faults (Page 339)
● Monitoring, tolerance band, pulse number (Page 340)
● Expansion of the encoder evaluation (1x, 4x) (Page 342)
● Setting the measuring time to evaluate speed "0" (Page 343)
● The number of current controller cycles can be set to generate the average value of the
These supplementary functions allow you to improve the evaluation of your encoder signals.
This may be necessary in special cases where the Control Unit receives incorrect encoder
signals or specific properties of the signals must be compensated for.
Some of these supplementary functions can be combined with one another.
