– Setting Minimum Speed in Pump Applications
In the case of pump applications, it is normally required to limit the minimum speed that the pump will operate
regardless of the input speed command. The pump minimum speed is usually specified either by the pump
manufacturer or the application. Once this value has been established, the minimum output frequency of the
inverter and thus the minimum motor (pump) speed can be set by parameter
Cn-19.
This parameter sets the
minimum inverter frequency output, and thus a minimum motor (pump) speed to a
percentage
of the maximum
output command frequency.
The following is an example of setting the minimum motor (pump) speed to
1800 RPM,
which is
50%
of the
maximum pump speed,
3600 RPM
.
