hysteresis
Noise coupled capacitively or inductively into the analog signal wires can
cause the motor to drift in spite of the filtering of the analog input. The zero
point hysteresis can be used to suppress this noise and therefore prevent
the motor from drifting.
With parameter CP.36 the analog signal AN1 (X2.1,X2.2) can be masked
in the range of 0...±10.0% (0...±1.00V). The adjusted value is valid for both
directions of rotation.
If a negative percentage value is adjusted then the hysteresis is not only
effective at the zero point but also around the actual set value. This means
changes to the set value during constant operation are accepted only when
the change is larger than the adjusted hysteresis.
