6.2.6 Zero Point Hyste-
resis (An.4;
An.14; An.24)
Through capacitive as well as inductive coupling on the input lines or voltage fluctuations
of the signal source, the motor connected to the inverter can still drift (tremble) during
standstill in spite of the analog input filter. It is the task of the zero point hysteresis to
suppress this.
With the parameters An.4 / 14 / 24 the respective analog signals can be faded out
within a range of 0...10% . The adjusted value is applicable for both directions of
rotation.
If a negative percent value is adjusted the hysteresis acts in addition to the zero point
around the current setpoint. Setpoint changes are accepted only if they are larger than
the adjusted hysteresis.
