Industrial AC Drive for Induction Motors
The M608 is an industrial general-purpose drive designed for reliable motor control of induction motors and flexible interconnectivity. Available as standalone units from 0.75 to 132 kW.
Reliable control for industrial processes
| Achieve maximum machine throughput with advanced motor control algorithms Unidrive M608 supports sensorless or closed loop control of induction motors, supporting AB, Resolver & SSI feedback devices. |
| Save energy through a wide range of features Unidrive M608 has been designed to bring improved energy efficiency to all applications, delivering up to 98% efficiency, minimising losses during the conversion process. |
| Flexible interconnectivity for your system The Unidrive M608 is multi-protocol, supporting Ethernet/IP, PROFINET, and MODBUS TCP as standard, meaning no additional modules are needed. |
| Conform to safety standards by direct safety system integration All Unidrive M drives have integrated Safe Torque Off (STO) inputs, certified to SIL3 / PLe, providing an elegant and reliable safety solution. |
Integrated PLC
All Unidrive M drives feature a 64 kB integrated user program space that enable engineers to embed custom control logic directly within the drive. This allows for real-time execution of application-specific functions such as sequencing, interlocks, and adaptive control—reducing system complexity and eliminating the need for external PLCs in many cases.
Whether you're optimising performance, automating unique processes or creating intelligent maintenance schedules, this built-in flexibility delivers smarter, more efficient solutions right at the drive level.
The 64 kB user program can be expanded with up to 3 MCi210 application modules that offer an additional 1 MB of code space each. To ensure programming these devices will feel familiar, they comply to the IEC61131-3 global standard for programming languages used in industrial automation and PLCs.

Multi-protocol - network communications
A single drive that does it all...
Control Techniques’ philosophy has always been to support innovators, regardless of which communications protocol they may use. It’s for them that we’ve developed the most flexible drive platform on the market.
Having multiple protocols supported by one drive means that different systems can share one design, reducing engineering effort and complexity, and helping to rationalise inventory of parts and spares. But we didn’t stop there. Today Unidrive M series drives offer EtherNet/IP, Modbus/TCP, RTMoE and PROFINET RT as standard, on a single drive platform, simultaneously. With this, Unidrive M delivers even more performance and extends the range of supported applications and achievable topologies. Using only the standard on-board communications it is possible to connect an HMI via Modbus TCP/IP, simultaneously with a high-performance connection to a central PLC using EtherNet/IP or PROFINET RT.
RTMoE
Real-Time Motion over Ethernet (RTMoE) is included as standard on Unidrive M608 drives. It provides synchronised communication between drives at 250 μs cycle time, using the Precision Time Protocol as defined by IEEE1588 V2. Inter-axis synchronisation using RTMoE delivers the ability to implement complex, highly accurate electronic line-shaft applications without the need for a powerful PLC. Therefore, it's all at a fraction of the cost of other solutions available on the market today.
Traffic management
Every Ethernet based Unidrive incorporates dedicated network switches that allow the drives to be conveniently daisy chained together; reducing the system wiring cost and saving valuable panel space. Using these dedicated switches also means that traffic on the network is perfectly managed to prevent network overload and the inherent performance degradation that may otherwise bane similar systems.
Cost-optimised integration
The diagram below gives an illustration of the flexibility that Unidrive can bring, exploiting the cost-effective features of RTMoE simultaneously with the supervisory control offered by a traditional PLC.
