7.4 Limit value setting
7.4.1 Speed range
Description
The speed setting range required for the application can be set via the selection of output
frequencies:
The minimum output frequency (C0010) corresponds to the speed at 0 % speed setpoint
selection.
The maximum output frequency (C0011) corresponds to the speed at 100 % speed setpoint
selection.
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).
