Through capacitive or inductive coupling onto the input lines or voltage fluctuations of
the signal source the motor connected to the inverter may drift in standstill position
inspite of analog input filters. It is the task of the zero point hysteresis to suppress
this. With the parameters An.2 and An.8 the corresponding analog signals at the
output of the characteristic amplifier can be suppressed in a range of 0...10%.
For this applies: 0 %

sis of Analog Inputs
(An.2 / An.8)
This function is provided with a switching hysteresis of 50 %.
If the analog signal is larger than the adjusted hysteresis value (An.2 / An.8), then the
analog setpoint is active. When the analog signal falls below 50 % of the adjusted
hysteresis value, the analog setpoint is set to value 0. .
