Active power monitoring
Operating principle
The active power P is influenced by the loading status of the motor. Depending on the limit
that is exceeded, a warning or an error is signaled.
● Load monitoring for over-dimensioned motors
● If pumps are running in no-load operation, the pump wheels can be damaged.
● To avoid load peaks
● To derive production quality data from energy data
The active power monitoring is deactivated during starting and stopping.
