High power modular drives

Unidrive M’s modular offering gives you never before seen flexibility in building compact, reliable high-power solutions. Paralleled together, Unidrive M can control asynchronous and synchronous motors up to 2.8 MW (4,200 hp). At the top of the modular drives range, the Frame 12 is a 500 kW (700 hp) single module that delivers unmatched power density, while keeping both footprint and system costs to a minimum. The Unidrive M modules can be paralleled together into a wide range of flexible solutions to solve all system needs, including Active Front End and multi-pulse rectifier configurations.

Efficient system build

Designing and building a high power drive cubicle takes immense engineering knowhow. Most people don’t have that expertise in-house, but we do. And we’ve put it all into our DFS freestanding drives. The cubicle system is designed to make the most of our high power modular drives, benefiting the applications that need them the most. The results are maximum energy efficiency in an ingress protected package. Our cubicle drives come pre-assembled, easy to set up, with all necessary system components included. Furthermore, we can ship your Freestanding drive to you with a very short lead time, saving weeks on typical industry standards.

 

Multi-Protocol

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 high performance 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 rationalize 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 M700 and M702 drives. It provides synchronized communication between drives at 250 μs cycle time, using the Precision Time Protocol as defined by IEEE1588 V2. Inter-axis synchronization using RTMoE delivers the ability to implement complex, highly accurate electronic line-shaft applications without the need for a powerful PLC. All this functionality is 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-optimized integration

The diagram below gives an illustration of the flexibility that Unidrive can bring, exploiting the high performance, cost effective features of RTMoE simultaneously with the supervisory control offered by a traditional PLC.

Functional Safety

All Unidrive M drives have integrated dual Safe Torque Off (STO) inputs, certified to SIL3 / PLe, providing an elegant and reliable safety solution. 
The addition of an MiS210 safety option extends the built-in STO with the ability to safely monitor and/or restrict the scope of motion. 
Safety functions include: STO, SBC, SOS, SS1, SS2, SLS, SSM, SLA, SDI, SLP & SES
For maximum flexibility in the safety system architecture, the modules support both wired and network safety connections: CIP-Safety on EtherNet/IP and Safety over EtherCAT (FSoE).

Features

Feedback

The built-in, ultra-flexible speed and position feedback interface supports a wide range of feedback technologies from robust resolvers to high resolution encoders, including SinCos, EnDat, SSI, HIPERFACE and BiSS.

Sensorless

Unidrive supports sensorless control of induction, permanent-magnet, and hybrid PM motors, reducing system cost and improving robustness.

High performance and high power

With Unidrive there is no compromise between power and control performance. Unidrive supports high output switching frequencies throughout the power range, making it the drive of choice when your application demands uncompromised high performance control at high powers.

Control

High bandwidth motor control supporting switching frequencies up to 16 kHz, for open and closed loop induction, servo and hybrid PM motors, giving up to 3,000 Hz current loop bandwidth and 250 Hz speed loop bandwidth. Unidrive, with its high speed variants, is suitable for applications where output frequencies above 600 Hz are needed, such as spindles and centrifuges.

Universally applicable

Having one universal drive in control of multiple parts of the application radically simplifies machine design. Your engineering team only have one product to learn, allowing them to spend more time on other tasks. It also means a single, universal replacement for any maintenance, repair or operational need.

On-board PLC

All Unidrive M series drives incorporate an easy to use, onboard PLC which can execute programs for logic and IEC 61131-3 motion and sequencing with real-time tasks.

Advanced Motor Controller

The Unidrive M700 series integrates a 1.5 axes Advanced Motion Controller, allowing motion functions to be synchronously carried out on the drive at 250 μs cycle time, minimising system latencies and maximising performance. By implementing motion control on the drive, the system design can be liberated from being tied to specific PLC vendors, at the same time reducing the computational load on the external PLC or even replacing it altogether.

Key features of the Advanced Motion Controller include:

• 250 μs cycle time
• Motion profile generator
• Electronic gearbox
• Simple cam profiles with point-to-point selectable interpolation
• Homing functions
• High speed position freeze (Touch probe)

MCi integrated machine controllers

Second processor for PLC programs and multi-axis control MCi modules add a powerful second processor to Unidrive M, extending the drive’s system and machine control capabilities to run application programs up to four times faster than a standard PLC. MCi programs can access and manage Unidrive M’s embedded Advanced Motion Controller across a wide range of networks, providing perfectly synchronised multi-axis machine performance.

The modules are powered from the drives internal power supply, which means less wiring and less physical space is required. They work seamlessly with external components such as I/O, HMIs and other networked drives through Unidrive M’s native communication ports and System Integration modules.

The MCi210 also provides two additional Ethernet ports with an internal network switch.

Integrated Safety

Modernising system design, replacing traditional electro-mechanical safety components with the capabilities of the latest generation of variable speed drives, is the new standard across industries to increase efficiency and availability.

Unidrive offers integrated single or dual Safe Torque Off (STO) inputs, certified to SIL3 / PLe, providing an elegant and more reliable solution over traditional motor contactors.
