The Flow Rate Maximization algorithm maintain required pressure by increasing/decreasing number of strokes per minute (CPM).

At the same time, controller will adjust CPM to avoid motor overheating and insulation failure.

VSD can work in automatic mode with ability to restart automatically after tripping or in manual mode.
