Example with constant curve with linear
influence/function
Actual setpoint: actual input signal x (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 x (85 - 25) + 25 = 61 %. See fig. 35.

constant curve
10.13.1 "Setpoint influence" functions
You can select these functions:
• ""Not active""
When set to ""Not active"", the setpoint is not
influenced from any external function.
• ""Linear function""
The setpoint is influenced linearly from 0 to 100
%. See fig. 36.
Fig. 36 ""Linear function""
• ""Linear with Stop"" and ""Inverse with Min.""
– ""Inverse with Stop""
In the input signal range from 20 to 100 %, the
setpoint is influenced linearly.
If the input signal is below 10 %, the motor
changes to operating mode ""Stop"".
If the input signal is increased above 15 %, the
operating mode is changed back to ""Normal"".
See fig. 37.
– ""Inverse with Min.""
In the input signal range from 20 to 100 %, the
setpoint is influenced linearly.
If the input signal is below 10 %, the motor
changes to operating mode ""Min."".
If the input signal is increased above 15 %, the
operating mode is changed back to ""Normal"".
See fig. 37.
Fig. 37 ""Linear with Stop"" and ""Inverse with
Min.""
• ""Inverse function""
The setpoint is influenced inversely from 0 to 100
%. See fig. 38.
