Min motor frequency
This parameter prevents motor operation below a certain frequency, thus avoiding damage to the thrust bearing of the submersible motors.
Min motor frequency ramp
Motor can accelerate from 0 to the minimum motor frequency following a very fast ramp and then go through a slower ramp.
MIDA allows to choose between two different methods of torque control (voltage) versus pumps speed (frequency):
For centrifugal pumps, energy savings can be obtained by selecting squared V/f control.
It is possible to program automatic periodic autorun after a certain time of pump inactivity.
If MIDA controls a submersible pump with long cables, it is possible to decrease the carrier frequency value to ensure longer motor life.
