4.1 Electrical Installation of Controller
4.1.1 Overview
The Rev6 standalone
controllers have signal processor controlled power converters with four switched
inverters for the drive and the bearing windings of the motor. The signal processor allows precise
control of pump speed and impeller position. Figure 21 shows the interfaces of the standalone
controller with standalone and minimal PLC functions.
