• ""Inverse with Stop"" and ""Inverse with Min.""
– ""Inverse with Stop""
In the input signal range from 0 to 80 %, the
setpoint is influenced inversely.
If the input signal is above 90 %, the motor
changes to operating mode ""Stop"".
If the input signal is reduced below 85 %, the
operating mode is changed back to ""Normal"".
See fig. 39.
– ""Inverse with Min.""
In the input signal range from 0 to 80 %, the
setpoint is influenced inversely.
If the input signal is above 90 %, the motor
changes to operating mode ""Min."".
If the input signal is reduced below 85 %, the
operating mode is changed back to ""Normal"".
See fig. 39.

Min.""
• ""Influence table""
The setpoint is influenced by a curve made out of
two to eight points. There is a straight line
between the points and a horizontal line before
the first point and after the last point.

points)
• ""Influence table with Stop at Min.""
The setpoint is influenced by a curve made out of
two to eight points. There is a straight line
between the points and a horizontal line before
the first point and after the last point. 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. 41.
