Description
The NI-9501 stepper motion module, carrying the part number 150629B-02L (779767-01), falls under the C Series Motion category. This module is specifically designed to be compatible with 2-phase hybrid stepper motors, including both NEMA 17 and NEMA 23 sizes. These motors can be configured in either bipolar or unipolar setups, providing flexibility in various applications.
It is engineered for use with the CompactRIO platform, enhancing its motion capabilities significantly. The NI-9501 features an advanced PWM (Pulse Width Modulation) algorithm. This algorithm is pivotal in minimizing torque ripple and reducing emissions, which in turn lowers power loss and facilitates smoother motion, ensuring an efficient operation.
One of the key features of the NI-9501 is its software-programmable microstepping rates. Users can select from full step, half step, and up to 256 microsteps, allowing for precise motion control. This fine control is beneficial in applications requiring delicate adjustments and smooth motion profiles.
The module operates within a resonance speed range of 50 to 150 RPM when set to full-stepping, which is essential for optimizing the performance and minimizing vibration at critical speeds. Additionally, it integrates a feature for enable current reduction, which is also software-programmable. This functionality reduces the phase current after the motor has been inactive for a predetermined period, contributing to energy savings and prolonging the motor’s life.
The primary application of the NI-9501 is to add integrated stepper motion capabilities to a CompactRIO system. This addition enables users to leverage the modular, embedded system for advanced motion control projects, expanding the possibilities in automation and robotics.
