The National Instruments part number 778440-04 refers to the PCI-7354 Motion Controller, a sophisticated device engineered for controlling both stepper and servo motors across up to four axes. This motion controller is well-suited for complex industrial applications that demand precise and efficient motion control. It supports a variety of servo systems, including brushless and brushed DC motors, as well as piezo motor systems. The controller features a PID update range from 62.5 to 500 µs/sample and provides a maximum update rate of 62.5 µs per axis, ensuring high-performance motion control with a multi-axis update rate of less than one sample.

Connectivity is facilitated through high-density 68-pin VHDCI connectors for both motion and digital I/O, accommodating all necessary signals for closed-loop control of the four axes. The device boasts a maximum count rate of 20 MHz and supports various configuration inputs and outputs, enhancing the accuracy and flexibility of motion control tasks. Safety is prioritized through integrated systems such as a watchdog timer function for board reset and a shutdown input, which disables all axes and outputs when required.

Designed for operational versatility, the PCI-7354 functions within an ambient temperature range of 0 to 55 degrees Celsius and can be stored at temperatures from -20 to 70 degrees Celsius, with a relative humidity tolerance of 10% to 90% RH, non-condensing. It is suitable for altitudes up to 2000 meters and is classified with a pollution degree of 2. Featuring compact dimensions of 17.5 by 9.9 cm (6.9 by 3.9 in.), this device integrates seamlessly into diverse digital systems, consuming a maximum power of 18 W at voltage requirements of +3.3 Volts to -12 Volts and current specifications of -2 A to 0 mA. Additionally, it includes 8 TTL digital I/O ports and 2 PWM outputs at 50 kHz. The PCI-7354 is compatible with NI-Motion software drivers and operates with Windows Vista, XP, 2000, and LabVIEW Real-Time platforms, making it a versatile choice for industrial automation applications.
