0 = 0
– 10V limited: An analog setpoint smaller than the programmed adjustment 0%
(P402), does not result in an undershooting of the programmed minimum frequency
(P104), i.e. does not result in a reversal of the direction of rotation.
1 = 0
– 10V: If there is a setpoint value which is smaller than the programmed adjustment
0% (P402), this may result in a change in the direction of rotation. Because of this, a
reversal of the direction of rotation may be implemented with a simple voltage source
and a potentiometer.
e.g. internal setpoint with change of direction of rotation: P402 = 5V, P104 = 0Hz,
potentiometer 0
–10V change of direction of rotation at 5V in the middle setting of the
potentiometer.
At the moment of reversal (Hysteresis =
P505), the drive unit is at a standstill, if the
minimum frequency (P104) is less than the absolute minimum frequency (P505). A
brake controlled by the FI is applied within the hysteresis range.
If the minimum frequency (P104) is larger than the absolute minimum frequency
(P505), the drive reverses when the minimum frequency is reached. Within the
hysteresis range
P104 provides the FI with the minimum frequency (P104), a brake
controlled by the FI is not applied.

l
ed: If the minimum
adjusted setpoint value (P402) is
undershot by 10% of the difference
between (P403) and (P402), the FI
output switches off. As soon as the
setpoint value is larger than
[P402 - (10% * (P403 - P402))], it
once again provides an output signal.

E.g.: Setpoint value 4-20mA: P402: Adjustment 0% = 1V; P403: Adjustment 100% = 5V;
-10% corresponds to -0.4V; i.e. 1...5V (4...20mA) normal operating range, 0.6...1V =
minimum frequency setpoint value, below 0.6V (2.4mA) the output is switched off.
