ABB drive software for pump control

Flow calculation which provides the drive with a flow meter routine which very accurately determines the flow rate within a process. This function avoids the need for costly external flow meters and is suitable for applications where the flow data is not needed for invoicing purposes. Accurate on-board flow measurement can help with leak management. Soft pipe filling which provides a pump with soft-start enabling a smooth build-up of flow in pipes while increasing the life time of the pipe work and pumping system. This drastically reduces leaks induced by flow surges. Sleep & boost which is suitable for pumping systems, during night time when demand falls. This function detects slow rotation and runs the pump to boost pressure prior to shutdown. The pressure is continuously monitored and pumping restarts when the pressure falls below the minimum level. Pump cleaning which is used in wastewater pumping stations to prevent pump and pipes clogging by initiating a sequence of forward and reverse runs of the pump to clean the impeller. Multi-pump control which is for applications where several parallel pumps are operated together and the required flow rate is variable. The function provides the most energy efficient way to operate parallel pumps, as all the pumps are controlled by VSDs. Redundancy which provides system redundancy, so should one or more pumps fail or require maintenance, the remaining pumps continue operating. Overall maintenance time and cost are decreased. Shared information - shares data between drives connected in parallel for multi-pump systems. This function makes IO cabling connections easier and faster, helping to reduce installation cost. Level control which is used to control the filling or emptying of storage tanks. The function prevents sediment build-up on the tank walls by randomly varying the surface level within a range preset by the user. Pump auto change which balances the operating time of all the pumps in the parallel pumping system over the long term. This helps to increase the mean time between repairs and reduce service costs. The master pump also automatically transfers in the case of a problem. Pump priority which is intended for systems where the consumption rate varies based on demand. This allows for better maintenance planning and can boost energy efficiency by operating pumps closer to their best efficiency point. Pump specific protections which help to maintain disturbance-free operating time in a process. The software also incorporates ABB's adaptive programming utility, enabling users to customise drives for specific applications. www.abb.co.uk/energy
