National Instruments PXI-7330 Stepper Motor Controller

The NI PXI-7330 (Part Numbers: 779035-02 and 778444-01) Stepper Motor Controller utilizes the NI-Motion driver. The benefit of this is if the user’s application needs changes later, they can undoubtedly update their equipment without changing the code. The user can also exploit any firmware refreshes with the field-upgradable firmware. Like other NI Motion controllers, the NI PXI-7330 controller offers intense capacities with its two data protection and machine vision functions. This model is a standout amongst the most effective, offering an RTSI bus or PXI trigger that the user can utilize straightforwardly without additional wiring and without bandwidth on the host bus. A NI PXI-7330 is perfect when utilizing stepper engines for applications where just basic movement is required.

Multi-stepping is incorporated in this model like dynamic smoothing. This is similar to dynamic smoothing, with the exception of being a significantly more aggressive utilization of the channel. Ordinarily, it results in a filter that starts to roll off two octaves underneath the resounding frequency. This is expected for use with coarse resolution (full/half-step input pulses) to smooth large steps into a continuous train of micro-steps and may give smoother movement, relying upon the motion application. The user can disable multi-stepping if they are not utilizing full or half digital resolution.

Dissimilar to other low-cost motion controllers, the PXI 7330 controller has an assortment of effective highlights including:

• Linear interpolation for coordinating multiple axes.

• Real-time framework integration for directly communicating with data acquisition or image acquisition boards

• High-execution stepper generation for guaranteeing smooth-motion at high speeds

• Up to 4 axes of stepper motion
