Description "
Analog input mode
". This parameter determines how the frequency inverter is to
respond to an analogue signal which is less than the 0 % adjustment ( P402 ).
Setting values
Value Function Description
0 limited to 0-100%: An analogue setpoint smaller than the programmed adjustment
0 % (
P402 ) does not result in undershooting of the programmed
minimum frequency P104 , i.e. it does not result in a change of the
direction of rotation.
1 0 – 100 % If a setpoint smaller than the programmed adjustment 0 % ( P402 )
is present, this can cause a change in direction rotation. This
allows rotation direction reversal using a simple voltage source and
potentiometer.
E.g. internal setpoint with reversal of direction of rotation:
P402 = 50 % , P104 = 0 Hz , Potentiometer 0 – 10 V

Rotation
direction change at 5 V in mid-range setting of the potentiometer.
At the moment of reversing ( hysteresis = ± P505 ) the drive is at a
standstill if the minimum frequency P104 is smaller than the
absolute minimum frequency P505 . A brake that is controlled by
the FI will be applied in the hysteresis range.
If the minimum frequency P104 is greater than the absolute
minimum frequency P505 , the drive reverses when the minimum
frequency is reached. In the hysteresis range ± P104 , the FI
supplies the minimum frequency P104 ; the brake controlled by the
FI is not applied.
