Control Techniques’ Unidrive M600 variable speed AC drive (VFD) delivers increased machine performance with sensorless induction and sensorless permanent magnet motor control for dynamic and efficient machine operation. An optional encoder port can be used for precise closed loop velocity applications and digital lock/frequency following for induction motors.

Additional I/O, encoder feedback options, industry standard fieldbuses and Ethernet communications maximize system connectivity and flexibility

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.

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

Enhanced throughput with high performance open-loop control of induction and permanent magnet motors

• Advanced Rotor Flux Control (RFC) algorithm gives maximum stability and control of induction and permanent magnet motors.
• High bandwidth motor control algorithm with 62.5µs current loop update rates for accurate motor control.
• 200% motor overload suitable for heavy industrial machinery applications.

Reduce system costs by directly integrating with applications

• Unidrive M600 incorporates an onboard PLC which can execute Machine Control Studio programs for logic control, sequencing, speed following and digital lock - removing the need for additional PLCs.
• Complete IEC 61131-3 programming environment. Structured text (ST), function block (FBD), sequential function chart (SFC), ladder diagram (LD), instruction list (IL), and continuous function chart (CFC)
• Fit up to three SI modules to add safe motion, speed feedback, additional I/O, fieldbus, and Ethernet communications.

Conform to safety standards, maximize uptime and reduce costs by integrating directly with safety systems

Unidrive M600 has an integrated Safe Torque Off (STO) input and can accommodate an SI-Safety module for safe motion functions.
