7.2.5 Zero clamp (An.04, 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.04 / An.14 / An.24 the respective analog signals can be faded out within a range of
0...±10%. The adjusted value is valid for positive and negative input signals.
If a negative percent value is adjusted the hysteresis acts in addition to the zero point around the current set-
point. Setpoint changes are accepted only if they are larger than the adjusted hysteresis.
