Description
The i550 series is the latest simple, yet powerful range of frequency inverters manufactured by Lenze. These frequency inverters are designed for applications such as pumps, fans, and conveyors, traction, winding, forming, tool and hoist drives. They function within the power range of 0.25 to 132 kW.
Built with simplicity in mind, the i550 series of frequency inverters feature slim designs measuring from 60mm x 130mm. They are designed to fit into control cabinets easily. System installers can expect a hassle-free installation process and the potential of expansion as various plug-on modules can be added for enhanced functionality.
Lenze has built the i550 series with the future in mind. It complies with the EN 50598-2 a standard of energy efficiency factor on power drive systems and motor starter that takes effect in 2020. The frequency inverter features the VFC-ECO energy-saving function to minimize power consumption.
Besides the basic functions of a frequency inverter, units from the i550 series are built to work with a wide range of communication interfaces. This includes CANopen, EtherCAT, EtherNet/IP, Modbus RTU, Modbus TCP, PROFIBUS, PROFINET, POWERLINK, and IO-Link. These communications can be activated by installing the relevant plug-on module.
The i550 series of frequency inverters are versatile in setup and parameter configurations. Technicians can utilize the keypad or smartphone app to access the setup menu to configure various motor and application functions on the frequency inverter.
