PCI-7342 -NI Motion Controller Device

Description

Featured with a real-time embedded OS and multiaxis interpolation, the National Instruments PCI-7342 (Part Number: 778916-02) is a 2-axis Motion Controller Device for servo/stepper motors.   This model offers fully coordinated gearing, linear, and circular control.  For complex moves, it can also provide a contouring capability.  The integrated CPU uses an embedded operating system with event-oriented multitasking control.  With this configuration, multiple motion control programs can be operated by the Controller efficiently without any lags and with zero outside interaction unless initiated by the user or host program.  The device has a PID update rate of 62.5 to 500 µs/sample, and a maximum step frequency of 4 MHz.  It has an encoder input rate of 20 MHz, and has a power consumption of 5.7 W. The NI PCI-7342 has 32 digital I/O channels.  Each of these general purpose I/O lines can be accessed through a separate, dedicated digital I/O connector (68-pin).  The 32-bit digital I/O port is configured as four 8-bit digital I/O ports.  All digital I/O lines on this Motion Controller have programmable polarity and direction.  Each output circuit can source and sink up to 24 mA.  This model offers two PWM (pulse width modulation) outputs through its digital I/O connector.  These PWM outputs are used to generate software controller periodic waveforms, and have a frequency of 32 kHz each. Though the RTSI connector provided, quick synchronization with other PCI based compatible devices can be achieved quickly.  The PCI-7342 and various other RTSI-capable devices can be connected by means of a ribbon cable.  This Controller allows users to implement a maximum of eight RTSI trigger lines as breakpoint outputs or as trigger inputs.  The NI device operates using the NI-Motion driver software.  It weighs around 170 g, measures 6.9 x 3.9 in.  in dimensions, and consumes 5.7 Watts of power while operating in the standard configuration.

Analog input module is a device used to collect and process analog signals, which is usually composed of analog input circuit, analog-to-digital converter (ADC), filter and interface circuit. The analog input circuit is responsible for converting the external analog signal into a voltage or current signal, and then converting the analog signal into a digital signal through an analog-to-digital converter, and finally filtering and enhancing the signal through a filter, and finally output to a computer or other control equipment for processing and analysis. Working principle 1. Analog input circuit: The analog input circuit is a key part of the analog input module, which is mainly responsible for converting the external analog signal into a voltage or current signal. Common analog input circuits include resistance divider circuit, current voltage circuit and so on. The resistance divider circuit realizes the signal conversion through the series parallel combination of resistors, and the current voltage circuit realizes the signal conversion through the product of current and resistance. 2. Analog-to-digital converter (ADC) : The analog-to-digital converter is the core component in the analog input module, which is responsible for converting analog signals to digital signals. The analog-to-digital converter discretizes the input voltage or current into a series of digital values according to its magnitude, and converts the continuous analog signal into a discrete digital signal through a process of sampling and quantization. Common analog-to-digital converters include successive approximation analog-to-digital converters and integral analog-to-digital converters. 3. Filter: The filter is an important part of the analog input module, which is mainly used to filter and enhance the signal. The filter can improve the quality and stability of the signal by removing high-frequency noise and interference signals, thus improving the accuracy and reliability of subsequent processing. 4. Interface circuit: The interface circuit is the connection bridge between the analog input module and the computer or other control equipment, which is responsible for converting the digital signal into a form that the computer or other control equipment can recognize and process. Interface circuit usually adopts serial communication interface or parallel communication interface, and realizes data exchange and communication with computer or other control equipment through data line and control line.
