Product Overview: Nidec Control Techniques SP2404
The SP2404 is the highest-capacity model in the Frame 2 Unidrive SP series from Nidec Control Techniques. This high-performance universal AC drive provides a rated output of 15kW (20HP) for 400V systems. Known as the «Solutions Platform» drive, the SP2404 offers unparalleled flexibility by supporting induction motor control, permanent magnet servo control, and regenerative modes within a single hardware platform. It is a critical component for high-torque applications such as heavy-duty conveyors, mixers, and industrial fans.
Universal Control and Maximum Frame 2 Power
The SP2404 is engineered to deliver 29 Amperes of continuous output current, maximizing the power density of the Frame 2 footprint. It features the signature Unidrive SP «Universal» motor control, allowing users to switch between Open Loop, Closed Loop Vector, and Servo modes through simple parameter adjustments. With three internal SM-Option Module slots, the SP2404 can be expanded to include advanced PLC-like functionality, high-speed fieldbus communications (like ProfiNet or EtherCAT), and additional I/O, making it a complete machine control solution.
