AN1 Interface selection
AN1 Zero point hysteresis
The set value input 1 (AN1) at the F5-GENERAL control can be triggered
by various signal levels. In order to correctly evaluate the signal, this
parameter must be adapted to the signal source. At the F5-BASIC control
the signal source may not be re-adjusted.
Value Reference signal
0 0...±10 V DC / Ri = 56 kOhm
1 0...+20 mA DC / Ri = 250 Ohm
2 4...20 mA DC / Ri = 250 Ohm

Note:
Through capacitive as well as inductive coupling on the input lines or
voltage fluctuations of the signal source, the motor connected to the
inverter may start to drift inspite of the analog input filters. It is the function
of the zero point hysteresis to suppress this drifting.
With parameter CP.36 the analog signal for the input REF can be faded
out in the range of 0...±10%. The adjusted value is valid for both directions
of rotation.
If a negative percentage value is adjusted then the hysteresis is not only
effective on the zero point but also around the actual set value. Set value
changes during constant operation are accepted only when they are
larger than the adjusted hysteresis.
