10.6 Limit value setting
10.6.1 Speed range
The speed setting range required for the application can be set via the selection
of output frequencies:
l The minimum output frequency (C0010) corresponds to the speed at 0 %
speed setpoint selection.
l The maximum output frequency (C0011) corresponds to the speed at
100 % speed setpoint selection.
l The lower frequency limitation (C0239) sets the speed. Independently of the
setpoint, the value cannot fall below this speed (e.g. for fans, dancer
position control, or dry running protection for pumps).
