BA1403 - Drive - CONTROL TECHNIQUES

CONTROL TECHNIQUES BA1403 frequency drive, Unidrive SP

The reference frequency drive BA1403 belongs to the Unidrive SP series from CONTROL TECHNIQUES. This series is designed for precise speed and torque control of three-phase induction motors, with advanced vector control capabilities and a servo mode for applications requiring strong low-speed dynamics. The BA1403 model is intended for industrial environments where process stability, repeatability and availability are priorities, notably on conveyor lines, pumping systems and auxiliary drive shafts. The control architecture supports V/f open-loop control, sensorless vector control and closed-loop vector control, allowing up to 175% torque at 0 rpm with appropriate feedback. The three-phase 380 to 480 V supply and the 1.5 to 2.2 kW power range provide suitable sizing for common 400 V motors, with optimized operational efficiency. For integration, configuration is performed via the local keypad and the manufacturer's software tools, simplifying commissioning, parameter duplication and proactive maintenance. This reference meets B2B requirements of operators and integrators seeking a reliable, configurable drive backed by a large installed base.

Overview of the Unidrive SP range

The Unidrive SP series comprises performance-oriented AC drives designed to provide stable speed and torque regulation across a wide operating range, with advanced servo options when low-speed precision is critical. Its large installed base in industry ensures longevity of existing equipment and simplifies replacements through exchange units or refurbished supply.

• Vector control : intended for drives with high torque and speed stability requirements, including low-speed operation, with or without a sensor depending on the expected dynamics.
• Servo mode : usable when responsiveness and instantaneous torque holding are decisive for process quality, provided appropriate sizing and feedback are in place.

The BA1403 model integrates naturally into existing automation architectures, offering a controlled transition when replacing a drive on a running line. Its 1.5 to 2.2 kW power envelope covers a wide range of 400 V motors commonly found in conveyor and pumping applications.

Industrial applications

This CONTROL TECHNIQUES frequency drive meets the needs of production workshops, utilities and assembly lines requiring reliable speed modulation, controlled energy consumption and robust torque holding. It is suitable for both continuous process control and cyclic operation, with measured acceleration profiles to limit mechanical stress.

• Conveyors and intralogistics : speed regulation, soft starts, maintaining material throughput.
• Pumping and fluid processes : adapting operating point, reducing water hammer and consumption.
• Industrial ventilation : airflow adjustment and noise reduction.
• Material handling and auxiliary axes : transient torque demands and low-speed stability.
• Winding and tension-controlled drives : torque holding at very low speed in closed-loop.

Integration and communication

The BA1403 is configured via the drive's operator keypad and the manufacturer's software tools, speeding up commissioning, backup and duplication of parameter sets. Acceleration and deceleration ramp functions, current limiting and control laws V/f, open or closed-loop vector are adjusted to meet the mechanical and thermal constraints of the driven motor. The ability to deliver up to 175% torque at 0 rpm in closed-loop facilitates starting under load or position holding at low speed, subject to appropriate feedback and tuning.

In an automation architecture, integration with a programmable logic controller or a numerical controller is achieved via the drive I/O and, depending on range modules, optional communication interfaces. This approach enables setpoint control, status feedback and alarm reporting to supervision systems. Motor cabling and EMC filter adaptation follow Unidrive SP common practice, facilitating compatibility with existing cabinets and reducing downtime during replacement.
