ACS310 Pump & Fan AC Drive

The ACS310 drive is designed for extremely fast installation and commissioning, particularly for pump & fan applications. The addition to the AC Drive family ranges from 0.5 HP to 30 HP (0.37 kW to 22 kW). Built-in PID controllers are used to vary the drive’s performance, in response to changes in pressure, flow, or other external data, which modifies drives’ performance according to the needs of the application. The controllers can eliminate the need for an external PLC, and helps to save energy and up-front costs. A pump and fan control (PFC) feature modulates the speed of the main pump or fan, and brings any auxiliary pumps or fans on line as necessary. The drive even can manage switching between pumps or fans to ensure they all are used to the same extent (working hours) over time. In addition, the drive includes soft pump and fan control (SPFC), which further reduces unwanted pressure peaks in pumps and pipelines. The control panel is needed only for commissioning or troubleshooting, so no panel is included with the drive as standard. Users who require a panel can select between two types: basic and advanced. A short parameter menu view means only the most-used drive parameters are shown on the drive’s parameter view. A complete parameter view can be changed by setting one parameter. The drive also has pre-programmed application macros for common tasks. The user is helped by an intuitive user interface with several assistant screens, including: a start-up assistant to guide the user through all essential settings; a maintenance assistant that helps to set criteria for preventative maintenance; and a diagnostic assistant that finds the root cause of a problem. A timer assistant offers help for setting timed functions, while the PID assistant helps in setting up sensor feedback. The drive has embedded Modbus RTU interface as standard (RS-485/RS-232). Well-known Modbus protocol, integrated and compact design simplifies the commissioning of the drive.
