The National Instruments SMD-7616 Stepper and Servo Motor Motion Drive Device (Part Number: 783598-01) is engineered for high-performance motion control applications, offering encoder feedback and full compatibility with NI LabVIEW. Operable with power supply voltages ranging from 24 VDC to 70 VDC, it delivers a maximum drive current of 10 A per phase. The SMD-7616 features multiple input options, including 12 V to 24 V digital logic inputs, 5.5 V logic inputs for direction and step commands, as well as various analog inputs for generating velocity or position commands. Users can configure the device to inhibit motion in specified directions by utilizing clockwise (CW) and counterclockwise (CCW) limits. For enhanced functionality, it includes eight digital inputs, with four software-programmable inputs that can be employed for purposes such as alarm reset, motor enable, or jogging, and are compatible with switches and sensors. High-speed DIR and STEP inputs accept signals up to 2 MHz, typically interfacing with a dedicated external controller for step and direction commands. Additionally, it incorporates four optically isolated inputs suitable for sensors, relays, mechanical switches, and PLCs. With integrated safety features designed to protect both the device and the drive, the SMD-7616 is an ideal choice for critical applications. Although National Instruments has announced that the SMD-7616 will become obsolete, it will remain available for purchase and repair through Apex Waves.
