NI-9505
Product introduction
The National Instruments NI-9505 is a remarkable C series motor drive module. It is engineered to offer users a high degree of customization and flexibility in their automation setups. This module is designed to interface directly with actuators, making it an essential component in various motion control systems.
When paired with the LabVIEW FPGA module, the NI-9505 truly shines. Together, they enable the creation of a highly adaptable actuator amplifier or motor drive. The LabVIEW FPGA module generates a PWM (Pulse – Width Modulation) signal, which is proportional to the desired torque or current. This signal is then fed to the NI-9505, allowing for precise control of the motor’s operation. The module also plays a crucial role in system health monitoring, as it returns actuator or motor current data to the software. Additionally, it provides status information such as emergency stop status, Vsup presence, and drive fault status.
Core advantages and technical highlights
High – performance power delivery
The NI-9505 can deliver a continuous current of up to 8 A at 40 degrees Celsius (or 2 A at 70 degrees Celsius), with a peak current of 12 A at 30 V. This high – power output, combined with its 98 percent power efficiency, makes it suitable for power – hungry applications. Whether it’s driving fractional – horsepower brushed DC servo motors or other high – load actuators, the module can handle the task with ease.
Encoder interface flexibility
Featuring 3 differential or single – ended input lines for index, phase A, and phase B signals, the NI-9505 supports a wide range of encoder configurations. These signals are used for velocity and position feedback, ensuring accurate motion control. The module allows quadrature encoder signals to pass through, which are then processed in the LabVIEW FPGA module for use in position and velocity loops.
Low – power sleep mode
This module offers a low – power sleep mode, which is dependent on the chassis it is connected to. In sleep mode, communication with the module is disabled, and power consumption is significantly reduced. This not only helps in conserving energy but also extends the lifespan of the module, making it an ideal choice for applications where power management is crucial.
Typical application scenarios
In industrial control applications, the NI-9505 is invaluable for controlling small – to – medium – sized machines. For example, in a manufacturing plant, it can be used to precisely control the movement of conveyor belts. The module’s ability to handle high – current loads and provide accurate position and velocity control ensures smooth and efficient operation.
Automotive engineers also find the NI-9505 useful in rapid prototyping applications. When developing new automotive components that require motor control, such as electric windows or adjustable seats, the module can be easily integrated into the prototype setup. Its compatibility with the LabVIEW graphical system design platform allows for quick and easy programming of the motor control functions.
In consumer appliance design, the NI-9505 can be used to control motors in devices like robotic vacuum cleaners. The module’s low – power sleep mode is particularly beneficial in such applications, as it helps to extend the battery life of the appliance. The precise control capabilities also ensure that the vacuum cleaner moves smoothly and efficiently across different surfaces.
