National Instruments NI-9946 4-Position NI 9505 Plugs

The National Instruments NI-9946 (Part Number: 779571-01) 4-POS NI-9505 Plugs are made to interface directly to the CompactRIO platform's NI 9505 servo motor drive module. With the NI LabVIEW graphical system design platform, this module is necessary to create intelligent, energy-efficient control systems, which makes it perfect for a range of automation and prototyping applications.

Plugging the NI-9946 into the NI-9505 allows it to function as a full H-bridge servo motor drive, producing continuous current up to 5 A at 40°C (or 1 A at 70°C) at 30 V. If a user needs more output power, the NI-9505 may give up to 7.3 A at 40°C by using the optional NI-9931 screw-terminal attachment. Because of its integration with the NI-9505 module, the NI-9946 is an essential tool for engineers working on rapid prototyping in the fields of automotive, industrial control, and electronics.

This module has an integrated encoder interface that can accept differential and single-ended inputs and can receive accurate position data from a quadrature encoder. Furthermore, real-time current monitoring via the motor or actuator is made possible via a current sensor, which is read by the CompactRIO chassis's FPGA. With its variable sample intervals and motor current filtering, this real-time data is essential for control loop optimization.

Engineers may create a comprehensive, reconfigurable motion control system within the CompactRIO platform by using the NI SoftMotion Development Module for LabVIEW. Accurate control over torque, velocity, and position is made possible by the FPGA logic on CompactRIO. This facilitates the application of sophisticated control strategies like gain scheduling and notch filtering, which prevent system resonance and adapt to shifting load inertia. By providing supervisory control, trajectory development, and multiaxis coordination for smooth motion profiles, the real-time embedded CPU on CompactRIO further improves capabilities.

When used in conjunction with the NI-9505, the NI-9946 module is a very useful tool for developing control systems for consumer appliances like as copiers, scanners, and printers. Because of its versatility and resilience, it can also be used in robotics, industrial control systems, automated test equipment, and automotive subsystems including engine and transmission control.
