Parameter description
CP.35 AN1 Set value selection
Description
The setpoint input 1 (AN1) can be triggered by various signal levels. In order to correctly evaluate the signal, this
parameter must be adapted to the signal source. The settings must be confirm by „ENTER".

0...±10 V DC / Ri = 56 kΩ
0...±20 mA DC / Ri = 250 Ω
4...20 mA DC / Ri = 250 Ω
At the F5-BASIC control at housing type A or B the signal source may not be re-adjusted.
Setting Description
0,2 % 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 parameter CP.36 the analog signal for the input REF can be faded
out in the 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 at
constant running are accepted only if they are larger than the adjusted
hysteresis.
