Description
The NI-9501 stepper motor drive module, with part number 150629D-01L (779767-01), falls under the C Series Motion category. This module is designed specifically for use with 2-phase hybrid stepper motors, including the popular NEMA 17 and NEMA 23 sizes. It supports both bipolar and unipolar winding configurations, making it versatile for various application requirements.
The module operates on the CompactRIO control platform, offering a robust foundation for motion control applications. It is capable of various stepping rates including full step, half step, and microstepping (up to 256 microsteps), providing flexibility in motion precision and control.
One of the key features of the NI-9501 is its advanced PWM algorithm. This technology significantly reduces torque ripple, emissions, and power loss, while enhancing smooth motion across a wide range of speeds. However, it’s important to note that there is a presence of resonance at low speeds (50-150 RPM), which may result in vibration and reduced torque. Conversely, the advantages of microstepping are diminished at speeds beyond 150 RPM, affecting high-speed performance.
Additionally, the module includes a software-programmable feature for current reduction and delay. This enables more efficient operation by allowing adjustments to the motor’s current consumption based on the application’s specific needs.
