Control Techniques

Control Techniques, a Nidec brand, is a global manufacturer of AC, servo, and DC drives, and motor control solutions, including the Unidrive, Commander, Digitax, Mentor MP, and Powerdrive platforms. Control Techniques technologies are engineered for precision motor control, high-performance motion applications, and energy-efficient industrial drive systems across manufacturing, material handling, packaging, process industries, and heavy industrial environments. PLC Direct supplies Control Techniques drive hardware, servo systems, and motor control components supporting installed Control Techniques automation environments. Our Control Techniques collection serves customers sourcing replacement drives, motion modules, and control hardware to maintain operational continuity within existing industrial systems. 

Why Choose Control Techniques: Drive-Centric Automation and Motion Performance

Control Techniques specializes in drive-centric automation, delivering AC, DC, and servo drive platforms designed for precise speed regulation, torque control, and synchronized motion. Rather than functioning as a traditional PLC manufacturer, Control Techniques integrates advanced motor control algorithms and motion intelligence directly into its drive systems.

Control Techniques drive and motion systems are commonly deployed in:

• Packaging and converting machinery
• Material handling and conveyor systems
• Cranes and hoisting equipment
• Printing and web processing lines
• Food and beverage production
• Metals and heavy industrial applications
• Automation environments requiring synchronized multi-axis motion
• Industrial systems requiring regulated motor speed and torque control 

This broad deployment reflects Control Techniques’ specialization in motor drive engineering, servo motion performance, and industrial motor control integration. 

Control Techniques Products and Solutions

Control Techniques’ industrial drive portfolio includes:

• Unidrive M Series (M200 / M300 / M400 / M700): The Unidrive M is Control Techniques' current-generation modular AC drive platform. The M200 and M300 address general-purpose speed control for pumps, fans, and conveyors. The M400 adds onboard PLC functionality for complex machine automation. The M700 integrates an advanced motion controller with real-time Ethernet for synchronized multi-axis applications. Unidrive M supports induction, permanent magnet, and servo motor control.
• Unidrive M750 / Digitax HD: The M750, marketed as the Digitax HD, extends the Unidrive M platform with high-performance servo control in a compact footprint. Designed for packaging, converting, robotics, and synchronized multi-axis positioning applications.
• Unidrive SP (Legacy Platform): The Unidrive SP is a legacy high-performance AC and servo drive platform that remains widely installed in industrial environments. Compatible UD-series and SI-series option modules continue to support installed Unidrive SP systems. PLC Direct carries both SP drive units and compatible option modules.
• Commander C Series (C200 / C300): Commander C general-purpose AC drives are designed for reliable motor speed regulation in pumps, fans, compressors, conveyors, and standard industrial applications. The Commander C200 is a frequently sourced model available through PLC Direct.
• Commander SK (Legacy General-Purpose Drives): The Commander SK is a legacy general-purpose AC drive that remains widely installed in industrial motor control environments. PLC Direct carries Commander SK units for replacement and lifecycle support of installed systems.
• Digitax ST Servo Drives (Legacy Platform): Digitax ST servo drives remain widely deployed across packaging, converting, and material-handling systems requiring precision axis control. PLC Direct supplies Digitax ST replacement units to support installed automation environments.
• Mentor MP DC Drives: Mentor MP DC drive systems provide precise torque and speed control in heavy industrial applications, including metals processing, cranes, winding, and high-inertia load environments requiring accurate DC motor control.
• Powerdrive F300 and High-Power Modular Drive Systems: Powerdrive F300 and related modular platforms are designed for high-power motor control applications in large industrial facilities.
• Drive Option Modules and Communication Interfaces (UD / SI Series): Legacy UD-series option modules (UD70 PROFIBUS, UD71 DeviceNet, UD73 Interbus-S) for Unidrive SP, and SI-series modules for Unidrive M, supporting integration within industrial control architectures.
• Servo Motors and Matched Motion Components: Servo motor systems engineered to operate with Digitax and Unidrive drive platforms in synchronized automation environments.
