Yaskawa W1000 Dedicated frequency converter for Water pumps
Yaskawa W1000 Dedicated frequency converter for Water pumps
By adopting energy-saving control technology, both induction motors and synchronous motors can operate efficiently
When operating at low speed or under light load, the voltage can be automatically reduced through the silent control function to achieve low-noise and energy-saving operation
The switching mode (Swing PWM) is adopted to reduce the noise generated
A water supply system using multiple pumps can be constructed through multi-pump control. By adopting long-life design, measures to deal with instantaneous power outages, and moisture-resistant and dust-resistant treatments, it can be used with confidence even in harsh environments
In case the frequency converter malfunctions, it can be quickly restored to operation through the detachable terminal block with parameter backup function
Features
Variable speed pump fixing method
One pump is subject to variable speed control, while the remaining pumps are controlled at power frequency ON and OFF through the digital output of the frequency converter.
And it has the function of constant pressure control for the pipeline. The pipeline pressure is maintained by controlling the PI function of the frequency converter of the variable speed pump
Poor continuity.
Up to 1 variable-speed pump and 3 commercial power supply constant-speed pumps can be operated.
When there is a DO-A3 purchase card:
Up to 1 variable-speed pump and 11 commercial power supply constant-speed pumps can be operated.
< Feature > It can operate based on pressure or flow rate. It can be achieved through a simple loop.
Variable speed pump circulation switching mode 1
Perform variable speed control on a certain pump and switch to commercial power supply when the pressure in the pipeline is insufficient to operate on the next pump
Variable speed control is available to achieve constant pressure control of the pipeline. Compared with the fixed method of the pump, the pump with variable speed control will be carried out
Loop switching operation. Maintain the continuity of the pipeline pressure difference by controlling the PI function of the variable frequency pump’s frequency converter.
When using this method, the DO-A3 accessory is required.
Up to five pumps with variable speed and cycle switching can be operated.
“Features
Operation can be achieved based on pressure or flow rate.
Moreover, by using the circulating pump switching function, it is possible to prevent the imbalance of operating time among pumps and achieve stable operation.
Variable speed pump circulation switching mode 2
Perform variable speed control on a certain pump and switch to commercial power supply when the pressure in the pipeline is insufficient to operate on the next pump
Variable speed control is available to achieve constant pressure control of the pipeline. Compared with the fixed method of the pump, the pump with variable speed control will be carried out
Loop switching operation. Maintain the continuity of the pipeline pressure difference by controlling the PI function of the variable frequency pump’s frequency converter.
Up to three pumps with variable speed and cycle switching can be operated.
When there is a DO-A3 purchase card:
Up to 11 pumps with variable speed and cycle switching can be operated.
“Features
Operation can be achieved based on pressure or flow rate.
Moreover, by using the circulating pump switching function, it is possible to prevent the imbalance of operating time among pumps and achieve stable operation.
