Industrial Motor Control Solution – Control Techniques UNI1405 | Unidrive Series
Where This Product Is Used
The Control Techniques UNI1405 Unidrive variable speed drive is engineered for demanding industrial motor control applications where precise speed regulation, energy efficiency, and robust performance are non-negotiable. Typical deployment environments include:
- CNC Machining Centers & Spindle Drives – Delivers smooth, high-bandwidth torque response for precision spindle speed control in milling, turning, and grinding operations.
- Pump & Fan Systems – Enables variable-flow control in HVAC, water treatment, and process cooling loops, reducing energy consumption by up to 50% vs. fixed-speed operation.
- Conveyor & Material Handling Lines – Provides controlled acceleration/deceleration profiles to protect product integrity and reduce mechanical wear on belts and gearboxes.
- Compressor Drives – Maintains stable pressure setpoints in pneumatic and refrigeration compressor systems through closed-loop PID control.
- Extruder & Mixer Drives – Supports high-inertia load starting and precise speed holding in plastics extrusion and chemical mixing processes.
- Winding & Unwinding Machines – Tension control applications in paper, film, and textile manufacturing benefit from the drive’s torque regulation capability.

Why Engineers Specify This Model
- Multi-mode control architecture – A single drive handles open-loop induction motor control, closed-loop flux vector, and brushless servo motor control, reducing spare-parts inventory.
- High dynamic response – Speed loop bandwidth up to 250 Hz enables tight servo-class positioning without a dedicated servo amplifier.
- Modular I/O & fieldbus expansion – Snap-in Solutions Modules (SM) allow seamless integration into PROFIBUS, DeviceNet, EtherNet/IP, and encoder feedback networks.
- Onboard PLC functionality – Built-in programmable logic via UD70 or SM-Applications module eliminates the need for an external PLC in simple standalone applications.
- Proven field reliability – The Unidrive Classic platform has accumulated millions of operating hours across global installations in automotive, food & beverage, and oil & gas sectors.
- Regenerative braking capability – Supports dynamic braking with external resistor, reducing mechanical brake wear in hoisting and crane applications.
Complete System Bill of Materials
For a fully operational UNI1405 installation, engineers typically specify the following complementary components:
- Line reactor / EMC filter (e.g., CT part: 4200-6205) – upstream harmonic mitigation
- Dynamic braking resistor (e.g., CT part: 1760-0002) – for high-inertia or frequent-stop applications
- SM-Resolver / SM-Encoder Plus module – for closed-loop feedback
- SM-PROFIBUS / SM-DeviceNet / SM-CANopen – fieldbus communication
- CT Keypad (UD70 or standard LED keypad) – local parameter programming
- Shielded motor cable (≤ 50 m recommended for EMC compliance)
- Fuses / MCB rated per CT installation guide (IEC 60364-5-52)
Compliance & Industry Standards
- CE Marking – Compliant with EU Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU
- UL 508C – Power Conversion Equipment (North American market)

Application-Specific FAQ
Q: Can the UNI1405 control a permanent magnet (PM) motor?
A: The standard UNI1405 supports induction motors in open/closed-loop vector modes. PM motor control requires the SM-Applications Plus module with appropriate firmware. Consult CT application note AN-PMAC-0001.
Q: What is the maximum cable length between the UNI1405 and the motor?
A: CT recommends ≤ 50 m of shielded cable without an output filter. For runs up to 150 m, install a CT dV/dt output filter to protect motor insulation.
Q: Is the UNI1405 compatible with Modbus TCP/IP?
A: The base unit supports Modbus RTU over RS485. Modbus TCP/IP requires the SM-Ethernet module (sold separately).
Q: Can I use the UNI1405 in a single-phase input application?
A: No. The UNI1405 requires a 3-phase 380–480V AC supply. Single-phase operation will damage the input rectifier and void the warranty.
Q: How do I obtain the original CT parameter manual?
A: The Unidrive Classic User Guide (UD50 / UD70) is available from the Control Techniques documentation portal. Konmask can provide a copy upon request.
