Smart, efficient, and decentralised drive technology for the digital era

(See Lenze at MachineBuilding.Live, 15 October 2025, on stand 130)

Building on the robust foundation of the i550 motec, the i650 motec introduces a suite of enhanced features. These include an integrated Logic PLC, advanced positioning functionality, and scalable safety capabilities. Together, they transform the inverter from a drive component into a complete, intelligent solution capable of operating stand-alone applications - reducing the need for centralised PLCs, lowering integration costs, and simplifying machine architecture.

The i650 motec exemplifies Lenze's commitment to sustainable innovation. Thanks to its regenerative feedback capability, energy otherwise lost is now efficiently recovered and fed back into the system. Combined with intelligent dimensioning via the EASY System Designer and compatibility with Lenze's high-efficiency m550 motor and g500 gearbox, the solution enables energy savings of up to 30%.

Built for the Smart Factory

Digitalisation is seamlessly embedded into the i650 motec's DNA. The integrated IO-Link master eliminates the need for additional hardware, while the drive's real-time data capabilities - via the Drive Datahub - support predictive maintenance and process transparency. With its digital nameplate, essential product data is always available, even before commissioning.

The i650 motec simplifies installation and connection through intuitive M12 push-pull connectors. It also has an integrated single-cable solution for the 400V power and the 24V controls supply. Its sensorless control for synchronous motors enhances performance across demanding applications such as airport logistics, conveyor systems, and energy-efficient pump operations.

Additionally, the i650 motec supports a broad range of safety functions - from STO via CIP Safety to optional advanced features like Safe Brake Control and Safe Limited Speed. These are available across major industrial communication protocols, including Profinet-Profisafe, EtherCAT-FSoE, and Ethernet-IP with CIP Safety.

Mark Turner, Application Manager at Lenze UK, explains: "The i650 motec isn't just a drive - it's a key enabler for building the machines of tomorrow. With its modular intelligence, energy-efficient design, and digital capabilities, it empowers our customers to optimise operations while stepping confidently into Industry 4.0."
