Product Overview: Nidec Control Techniques SP1401
The SP1401 is a high-performance AC variable speed drive from the acclaimed Unidrive SP series by Nidec Control Techniques. This Frame 1 drive is engineered for 200V applications, providing a rated output of 0.75kW (1.0HP). The Unidrive SP is a «Universal Drive,» meaning it provides total flexibility by supporting high-performance motor control for induction motors, servo motors, and synchronous motors within a single hardware platform. It is a critical component for precision manufacturing, printing, and textile machinery.
Advanced Universal Control Technology
The SP1401 features an advanced control core that allows the user to select the operating mode via software (Open loop, Closed loop, Rotor flux control, or Servo). This eliminates the need for multiple drive types on a single production line. The unit is designed with a high-speed internal bus and supports the installation of up to three SM-Option Modules (Solutions Modules) simultaneously. This enables seamless integration into fieldbus networks such as Profibus, DeviceNet, or EtherCAT, and allows for additional I/O or specialized motion control logic.
