9.3.25 Tolerant encoder monitoring
9.3.25.1 General information
The tolerant encoder monitoring offers the following options regarding evaluating encoder
signals:
● Encoder track monitoring (Page 589)
● Zero mark tolerance (Page 590) (also for other sensor modules)
● Freezing the actual speed for dn/dt errors (Page 591)
● Adjustable hardware filter (Page 591)
● Edge evaluation of the zero mark (Page 592)
● Signal edge evaluation (1x, 4x) (Page 593)
● Setting the measuring time to evaluate speed "0" (Page 594)
● Sliding averaging of the speed actual value (Page 594)
● Rotor position adaptation (Page 595)
● Pulse number correction for faults (Page 595)
● "Tolerance band pulse number" monitoring (Page 596)
These additional functions make it possible to improve the evaluation of the motor encoder
signals. This may be necessary if in particular cases incorrect encoder signals can occur or
special properties of the signals are to be compensated.
Some of these supplementary functions can be combined with one another.
