Control Techniques SP2401 Unidrive SP Universal Motion Drive Unit

Module Feature

SP2401 belongs to Unidrive SP series universal AC variable frequency drive manufactured by Control Techniques. Rated 5.5kW heavy duty,7.5kW normal duty. It supports V/F, open-loop vector, closed-loop vector and high-performance servo control, compatible with asynchronous induction motors and Unimotor FM permanent magnet servo motors. Equipped with SM small option slots for encoder feedback, fieldbus communication and motion control modules. Widely applied in conveyors, winding machines, packaging equipment and general factory automation.

Working principle

Three-phase 50/60Hz AC mains power is rectified to DC bus voltage. IGBT power module outputs adjustable voltage and frequency AC to drive motor. The drive receives motion command from upper controller, compares command value with encoder feedback signal to realize closed-loop torque, speed and position regulation. Built-in brake transistor absorbs regenerative energy during motor deceleration.
