Overview of the UNIDRIVE SP range

The UNIDRIVE SP series is designed to deliver precise speed and torque control across a wide variety of industrial applications. Known for its integration flexibility and modular architecture, it simplifies deployment both in new installations and as a replacement for existing equipment. The range offers, depending on configuration, V/Hz and vector control functions to optimise drive dynamics and process stability. This approach allows fine adjustment of motor speed according to load, resulting in measurable energy savings and better control of cycle times. Thanks to its hardware and software options, UNIDRIVE SP adapts to the needs of production workshops, utilities and packaging lines, while remaining consistent with preventive and corrective maintenance practices.

• General applications : high-efficiency speed control for pumps, fans, conveyors and compressors, with simple and reproducible tuning.
• Dynamic applications : demanding drive control for web tension, axis synchronization and positioning where control accuracy is a priority.

Positioned in this series, the BA1405 model covers the 380-480 V range for a power of 3 to 4 kW with a rated current of 8.8 A. This combination makes it a relevant choice for small to medium power drives where stability, consistent regulation and service continuity are decisive for process quality and equipment availability.

Industrial applications

The BA1405 drive integrates into many environments, from continuous processes to discrete production machines, both for new installations and retrofits. It meets the needs of utilities and production lines that require stable and repeatable control while simplifying diagnostics and maintenance. Typical sectors include handling, processing and site utilities.

• Conveying and handling : speed control of drive motors on belt conveyors, roller conveyors or elevators.
• Pumping and water treatment : control of centrifugal pumps with speed adaptation for flow and pressure.
• Industrial ventilation and HVAC : optimisation of fan and extractor operating points.
• Packaging : synchronization of drive sections and control of web tension.
• Textile and printing : consistent speed control on winders, unwinders and rewinders.
• Food industry : dosing, mixing and transfer, with controlled throughput and soft starts.
• Special machines : assembly machining, semi-automated lines, control of auxiliary axes.

Integration and communication

Integration of the BA1405 into an automation architecture is straightforward via standard I/O and optional modules in the range, enabling connection to programmable logic controllers and CNC systems. Depending on configuration, the UNIDRIVE SP range accepts major industrial fieldbuses via dedicated cards, facilitating the exchange of setpoints and diagnostics at the line level. Configuration can be carried out via a local operator panel and the manufacturer's software tools, with a clear structure for basic parameters, acceleration, braking and motor protections. This approach supports rapid commissioning, reproducible settings and traceability of changes, essential points for maintenance and quality audits.

In contexts requiring finer control, the series offers advanced control functions, typical of a servo-drive when enabled within the range, to improve dynamics and precision. Compatibility with multi-vendor automation environments is strengthened by standardized communication options, contributing to seamless integration into existing installations.
