  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.

• 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.
