The E4 offers a new level of capability for a wide range of industrial and commercial applications. It features integrated diagnostics, a built-in flight recorder, dual-channel SIL3 Safe Torque Off (STO), USB-C and Bluetooth connectivity, and industrial Ethernet communications for real-time integration into connected systems.
In addition to the E3 VFD
The E3 remains a VFD for general-purpose drives, while the E4 offers additional capabilities.
The E4 is designed to accommodate both induction motors and permanent magnet hybrid motors (PMRLs), ensuring future-proof compatibility with emerging high-efficiency motor technologies. This is made possible by Invertek's latest precision current control algorithms, guaranteeing optimal torque output, superior thermal management, reduced electromagnetic interference (EMI), and an integrated C1 EMC filter.
The drive's communication architecture has also been modernized. With industrial Ethernet interfaces such as PROFINET, EtherCAT, and Modbus TCP, the E4 enables real-time data exchange for precise control and diagnostics. This allows for predictive maintenance strategies and seamless integration with Industry 4.0 and IIoT systems.
Regarding service and support, the drive incorporates a QR code system linked directly to Invertek's online resources, allowing immediate access to configuration data, manuals, and troubleshooting tools.
Digital passport
Each Optidrive E4 includes a unique QR code that acts as the product's digital passport. Scanning it with a mobile device opens Invertek's dedicated app. This provides instant access to detailed information about that specific drive, including its exact manufacturing data, specifications, and configuration history.
This feature allows engineers, original equipment manufacturers, and installers to view a complete digital record of the unit, simplifying commissioning, traceability, and support throughout the lifecycle.
The flight recorder continuously records operating parameters, facilitating rapid analysis of events and reducing troubleshooting time in case of a system problem.
E4 Size 1 Left
The Optidrive E4 will initially be available in IP20 enclosures in rack sizes 1 and 2 starting in the third quarter of 2026, and subsequently in larger rack sizes. The Optidrive E3 remains in full production and is the company's main range of general-purpose drives.
Adrian Ellam, Managing Director of Invertek Drives, commented: “The Optidrive E4 demonstrates how Invertek continues to combine ease of use with cutting-edge innovation. It is the most connected and diagnostically advanced drive we have ever manufactured, ready for today’s automation challenges and tomorrow’s efficiency standards.”.
The Optidrive E4 is manufactured at Invertek's global headquarters in Wales, UK, as part of the company's ongoing investment in sustainable manufacturing and R&D for advanced motor control solutions.
