2. Chapter 1 Overview Pump control refers to controlling more than one pump motor by a single inverter The inverter selectively drives one of pump motors in a liquid dispatch system while switching power sources of other pump motors to commercial power lines as required In the pump control the PID controller integrated in the inverter processes the PID command such as flowrate or pressure When the inverter driven motor is no longer sustain the discharge flowrate required the inverter issues an output signal that dynamically switches the power source for individual motors between the inverter output and commercial lines or mounts a commercial power driven motor s If the discharge flowrate is low for example the inverter drives one of the motors if higher it mounts more motors driven by commercial power in order to ensure the total discharge flowrate required This pump control system further works to even the historical operation conditions of motors such as the cumulative run time The pump control system is available in two configurations one with a fixed inverter driven motor and the other with a floating inverter driven motor The details are described later in this manual Chapter 2 Specifications Item Dynamic rotation of pumps With a fixed inverter driven motor With a floating inverter driven motor Remarks Maximum number of pumps to drive Inverter driven 1 Commercial power driven 4
