-Cascade control
The cascade control is the function that controls the multiple pumps by one inverter. The pumps are controlled with combination of inverter drive and commercial drive. This can be applied in a large-scale water treatment plant. In cascade control, the signals of flow rate and pressure sensors are controlled by the PID regulator that is built in the inverter. Each pump is driven either by the inverter or commercially according to the switching signal from the inverter. The pumps are controlled only by the inverter when the discharge volume is small, and adding to the inverter drive, they are controlled using commercial drive by adding them one by one as the discharge volume gets larger in order to ensure the required discharge volume in total. There are two following methods in control: inverter drive motor fixed method and inverter drive motor fixed method.

Fuji Electric vfd Frenic-Aqua series has an Optimal Function for Usage in Water Treatment

-  Inverter drive motor fixed method (FIXED)
The system is configured by combining the motor driven by the inverter (M0), motors that are commercially driven (M1 to M8) and auxiliary motor (MA). TThe motor driven by the inverter is always fixed as motor M0. Motors commercially driven are added one by one in control when the required discharge flow rate cannot be achieved with the motor M0 only.

Fuji Frenic-Aqua inverter drive motor fixed method

- Mutual operation
The system can be configured without using a controller by connecting the inverters via communications. In this system, if a failure occurs to the master inverter, the next inverter is driven as the master inverter. Moreover, wiring can be saved with use of communications services, which eliminates the need of additional options by using the Modbus RTU communications.

Customized logic

The customized logic interface function is provided to the inverter body. This enables forming of logic circuit and arithmetic circuit to the digital and analog input and output signals, allowing simple relay sequence to be built while processing the signals freely.
Fuji Electric Frenic-Aqua customized logic interface function

Boost function

Frequency can be output forcibly at a fixed rate in preference to PID control. By setting the operation frequency, operation time, and acceleration time at starting, optimal operation for starting the pump can be achieved.
Pressurizing operation can be applied for a certain period of time at the time of start.

Password

Function codes can be read/write, displayed or hidden by setting the two passwords. This prevents erroneous operation or overwriting of function codes. In addition, if a wrong password was input exceeding the specified number of times, the inverter is restricted from operating as the user is regarded as improper.

Dry pump detection

Pump dry condition can be detected from PID deviation value by setting the output frequency, output current, and flow rate sensor value. Water leakage and pressure drop due to impeller damage can be detected as well.

Slow flowrate function (pressurized operation available before slow flowrate)

The inverter can be stopped when the discharge rate becomes low due to increase of pump discharge pressure. Facility having a bladder tank can make the stoppage period longer by applying pressure immediately before stoppage, which realizes energy-saving operation.

Initial acceleration/deceleration time

When a pump such as a deep well pump is operated at low speed over a long period of time, the pump may be damaged since the load current is large in the low-speed range. It is possible to provide acceleration/deceleration time specific to the low-speed range in order to avoid prolonged operation.
Fuji Electric frequency inverter Frenic-Aqua series initial acceleration/deceleration time

Anti-jam function

The motor is rotated in reverse when it is determined that any abnormality, such as being engaged or trapped, is occurred. If sand or dust were caught in the impeller with a submerged pump and overcurrent protection function is activated, the motor is rotated in reverse at restart so that the sand and dust are ejected from the impeller. Then, the motor resumes rotation in forward, allowing water to be supplied in a normal manner.

Deceleration time for check valve protection

If a valve is closed quickly after pump stoppage, there is a risk of damaging the check valve (piping, pump, valves, etc.) due to water hammer phenomenon. To protect the check valve from this, the pump speed is gradually slowed down when the check valve closes.
