2 0 – 10V monitored: If the minimum adjusted setpoint P402 is undershot by 10 % of the
difference value from P403 and P402, the FI output switches off.
Once the setpoint is greater than P402 - (10 % * ( P403 … P402 )), it
will deliver an output signal. Note : A function for the relevant input
must be assigned in P400 .
E.g. Setpoint 4 - 20 mA: P402 : “Adjustment 0 % “= Setting 20 %;
P403 : "Adjustment 100 %“ = Setting 100%; 10 % of the difference
between P403 and P402 corresponds to 0.8 V; i.e. 2 V...10 V
(4 ... 20 mA) = normal operating range, 0.8 V ... 2 V = Minimum
frequency setpoint less than 0.8 V (2.4 mA) causes the output to
switch off.
3 - 100 % – 100 % If a setpoint smaller than the programmed “adjustment 0 % “( P402 )
is present, this may 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 which is controlled by
the FI has not been 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.
NOTE : The function -10V – 10V is a description of the method of
function and not a reference to a physical bipolar signal (see
example above).

is activated. Even if the analogue value is
outside the limits defined in P402 and P403 , the setpoint value is
limited to 0 - 100 %.
The monitoring function only becomes active if an enable signal is
present and the analogue value has reached the valid range
(
≥
P402 or.
≤
P403 ) for the first time (e.g. pressure build-up after
switching on a pump).
Once the function has been activated, it also operates if actuation
takes place via a field bus, for example, and the analogue input is
not actuated.

See setting {4 } ("0 – 10% with error switch off 1“), however:
In this setting the monitoring function only becomes active if an
enable signal is present and the time during which the error
monitoring is suppressed has elapsed. This suppression time is set
in parameter
P216 .
