Unidrive M700 Universal AC/Servo Drives

1.0 - 4,200 HP (0.75 kW – 2.8 MW)
208-240 V | 380-480 V | 575 V | 690 V

A key competence of Control Techniques is honing our unique motor control algorithms, taking pride in our craft as any good craftsman would. This ensures that our Unidrive M series drives offer the highest control stability and bandwidth for every industrial motor type.

Unidrive M enables maximum machine throughput in every application and with every motor, from standard AC induction motors to dynamic linear motors and from energy saving hybrid permanent-magnet motors to high performance servo motors.

To meet the needs of any application Unidrive M700 series is available in three variants:

Unidrive M700: Onboard Ethernet and single STO input
Unidrive M701: Onboard RS485 to upgrade from Unidrive SP, single STO input
Unidrive M702: Onboard Ethernet, dual STO inputs

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).
