National Instruments 778540-02 PXI Motion Control Module.

The part number 778540-02 from National Instruments is the identifying part number for the PXI-7352 PXI Motion Control Module. This PXI module is engineered to administer both stepper and servo motors in complex applications and is equipped with two axes, making it ideal for a variety of industrial and laboratory tasks that require precise and efficient motion control. The 778540-02 supports linear, circular, spherical, and helical interpolation, delivering smooth motion and high velocities for demanding motion control tasks. The device has PID update rate ranges of 62.5 to 500 µs/sample, and it has 8 axes per 250 µs PID update rate.

This 778540-02 PXI Motion Control Module is designed to operate at an ambient temperature of 0 degrees Celsius to 55 degrees Celsius and storage temperature of –20 to 70 degrees Celsius with a relative humidity of 10% to 90% RH, non-condensing. It requires to be mounted at a maximum altitude of 2000 meters with a pollution degree of 2.

This module features a 68-pin female high-density VHDCI-type motion I/O connector and a digital I/O connector. The motion I/O connectors contain all the necessary signals required for closed-loop motion control of up to eight axes, while the digital I/O connectors contain 64 bits of digital I/O and 12 inputs for four Hall effect sensors. Motion I/O Connector 0 deals with Axes 1-4, and Motion I/O Connector 1 provides access to Axes 5-8. This device has a maximum step frequency of 4 MHz, accommodating full, half, and micro steps. It has 8 inputs and outputs with a 16-bit resolution, enhancing the accuracy of the motion control applications.

This 778540-02 has physical dimensions of 16 cm by 10 cm (6.3 by 3.9 in.) making it compact. It has a power consumption of 18 Watts maximum with power requirements of 2 A at +3.3 Volts, 2 A at +5 V, 30 mA at +12 V, and 0 mA at -12 V. Additionally, this device also features configurable 8 digital TTL I/O ports with 8 bits each and 2 PWM Outputs at 50 kHz. This Motion Control Module is supported by a software driver NI-Motion and recommended NI software LabVIEW, NI Motion Assistant, and Measurement Studio.
