The National Instruments SMD-7621 is a versatile Stepper and Servo Motor Motion Drive Device designed for operation with a universal 230 VAC power supply. This device utilizes a Step/Direction ENET control interface, making it suitable for larger motors with inductance ratings between 20 mH and 60 mH. The SMD-7621 can be configured and controlled via a standard PC over an Ethernet connection, provided both devices are connected to the same local area network. To simplify IP address configuration, a 16-position rotary switch is included, with each position pre-assigned a default IP address. Users can enable automatic IP address assignment from a DHCP server by setting the switch to position "F." Alternatively, the SMD-7621 can connect directly to a desktop or laptop PC using a standard Ethernet cable. The device incorporates a fast-acting, 3.5 A fuse for enhanced protection and is compatible with various third-party motors, although National Instruments recommends its proprietary NEMA 34 stepper motors for optimal performance. A status LED provides real-time updates on drive status and any faults. Although the SMD-7621 has been designated as a mature product, it remains available for purchase and repair services through Apex Waves. For complete details, including user and maintenance manuals, refer to the manufacturer's documentation.
