The NNC25X37IB2 is a general purpose, three phase AC motor drive empowered with advanced features such as over-voltage, over-current, over-heat, and speed monitoring. It is widely used in various industries including food processing, automotive, textiles, electronics, and power tools. The NNC25X37IB2 is capable of providing precise and accurate control of speed, torque, and current in a wide range of applications.

The NNC25X37IB2 is a digital AC motor drive that utilizes digital Input-Output (I/O) signals, pulse-width modulation (PWM) technology, and field-programmable gate-arrays (FPGAs) to enable precise and accurate motor control. It supports multi-functional I/O signals such as, pulse train output (PTO), 4-20 mA analogue input, 0-10 V analogue input, incremental encoder, start/stop/reset, brake signal, and SPD signal. The NNC25X37IB2 also supports CAN2.0B bus communication for remote control and monitoring of the motor drive.

The NNC25X37IB2 adopts a field-oriented control (FOC) technique to achieve high-performance AC motor control. FOC helps to achieve a smoother motor response, increased torque, and higher efficiency. In addition, the NNC25X37IB2 incorporates an adjustable speed compensation algorithm that eliminates the need for external sensors to achieve stable control over a wide speed range. This feature makes the NNC25X37IB2 suitable for controlling motors with varying speeds, such as pumps and conveyor belts.

The NNC25X37IB2 has a wide range of application fields which include conveyor belt systems, pumps, fans, mixers, conveyance equipment, transport systems, winding systems and machine tools. Its flexible configuration allows users to select between the standard control modes, such as torque control, speed control, and current control, or to customize the control mode to meet a specific application requirement. It can also be incorporated in multi-motor systems to control multiple motors simultaneously, which is highly useful for applications such as synchronous control of multiple conveyors.

The NNC25X37IB2 is also capable of providing speed or torque matching within the same module. This makes it ideal for applications in which multiple motors are required to run at the same speed or torque, such as material handling systems, printing machinery, and automated production lines. The NNC25X37IB2 is also equipped with safety features such as over-voltage, over-current, and over-heat protection to ensure reliable operation of the motor drive.

The working principle of the NNC25X37IB2 is as follows: the device first acquires a reference signal from the processor, which is then sent to the FPGA; The FPGA then processes the signal and generates a pulse-width modulation signal according to the reference signal; The pulse-width modulation signal is then sent to the motor drive, which in turn regulates the speed, torque and current of the motor drive as needed.

In conclusion, the NNC25X37IB2 is a powerful and versatile general purpose AC motor drive equipped with advanced features such as over-voltage, over-current, over-heat, and speed monitoring. Its wide range of application fields and customizable control options make it a popular choice for OEMs and operators in various industries. In addition, its FOC control technique and adjustable speed compensation algorithm provides precise and accurate motor control.
