External setpoint function
You can influence the setpoint with an external signal via
• one of the analog inputs
• one of the Pt100/1000 inputs if an advanced functional module
(FM 300) is fitted,
Before you can enable the function, you must set one of
the analog inputs or Pt100/1000 inputs to External
setpoint function.
See sections Analog inputs and Pt100/1000 inputs.
Example with constant pressure with linear influence
Actual setpoint: actual input signal × (setpoint - sensor min.) +
sensor min.
At a sensor min. of 0 bar, a setpoint of 2 bar and an external
setpoint of 60 %, the actual setpoint is 0.6 × (2 - 0) + 0 = 1.2 bar.

Example with constant curve with linear influence
Actual setpoint: actual input signal × (setpoint - user-set minimum
speed) + user-set minimum speed.
At a user-set minimum speed of 25 %, and a setpoint of 85 % and
an external setpoint of 60 %, the actual setpoint is 0.60 × (85 - 25) +
25 = 61 %.
