Product Overview: Nidec Control Techniques SP1404
The SP1404 is a high-performance, universal AC variable speed drive from the legendary Unidrive SP series by Nidec Control Techniques. Engineered for 400V industrial networks, this Frame 1 drive provides a rated output of 2.2kW (3.0HP). As a «Solutions Platform» drive, the SP1404 is designed to offer total flexibility, supporting open-loop, closed-loop, rotor flux control (RFC), and high-dynamic servo control within a single hardware module. It is the premier choice for precise speed and torque control in automated manufacturing, textile machinery, and material handling systems.
Universal Motor Control and Scalability
The core strength of the SP1404 lies in its ability to control a wide range of motor types without hardware changes. Whether driving a standard induction motor or a high-performance permanent magnet servo motor, the SP1404 maintains exceptional precision. It features three internal slots for SM-Option Modules, allowing for seamless integration with fieldbus networks (ProfiNet, EtherCAT, Ethernet/IP) or the addition of extra I/O and specialized motion controllers. Its high-speed internal bus ensures sub-millisecond response times for synchronized multi-axis applications.
