National Instruments SMD-7615

The National Instruments SMD-7615 is a high-performance Stepper and Servo Motor Motion Drive Device, offering reliable drive solutions for a variety of general-purpose motion control applications. Designed with four optically isolated single-ended inputs, the SMD-7615 accommodates sinking or sourcing signal configurations, enhancing its versatility. This device utilizes advanced control technology, incorporating features such as electronic damping, torque ripple smoothing, and microstep emulation to deliver quiet and smooth motor operation. The electronic or anti-resonance damping assures stable performance at high speeds, while torque ripple smoothing at lower speeds promotes seamless functionality.

The SMD-7615 supports a drive current range of 0.5 A to 5 A and requires an 18 VDC to 53 VDC power supply to operate effectively. It employs a Step/Direction ENET control interface, making it compatible with motors having an inductance rating between 1 mH and 6 mH, including two-phase configurations of eight-wire, six-wire, and four-wire bipolar motors. Installation is made simple via a standard Ethernet connector, enabling fast configuration through a CAT 5 Ethernet cable. Additionally, the SMD-7615 features four general-purpose digital outputs that can signal fault conditions or indicate motor movement. While the product has received a Mature Status announcement from National Instruments, it remains available for purchase and repair through Apex Waves. The device measures 1.775 × 3.0 × 5.0 inches and weighs 10 ounces, with a warranty period of 2 to 3 years. User and maintenance manuals are readily available for download.
