Product Overview: Nidec Control Techniques SP2401
The SP2401 is a high-performance, universal AC variable speed drive from the renowned Unidrive SP series by Nidec Control Techniques. As a Frame 2 model designed for 400V systems, it provides a robust rated output of 5.5kW (7.5HP) for heavy-duty applications. The Unidrive SP is celebrated as the industry’s premier «Universal Drive,» offering a single hardware platform capable of high-precision control for induction, servo, and permanent magnet motors. It is a critical asset for complex automation, industrial mixing, and specialized material handling.
Advanced Universal Control Logic
The core of the SP2401 is its sophisticated control processor, which allows for multiple operating modes including Open Loop, Closed Loop Vector, Rotor Flux Control (RFC), and high-dynamic Servo mode. This versatility allows facilities to standardize on one drive type for various motor technologies. The SP2401 features three integrated slots for SM-Option Modules, facilitating easy expansion for fieldbus communications (ProfiNet, EtherCAT, Modbus TCP/IP) or advanced PLC-like functionality with onboard motion control. Its 13A continuous output current ensures stable power delivery even under fluctuating load conditions.
