Description
The NI SMD-7621 Stepper and Servo Motor Motion Drive Device, with part number 783014-01, is designed to operate on a universal 230 VAC power supply. This device utilizes a Step/Direction ENET control interface and is compatible with stepper motors that have an inductance rating ranging from 20 mH to 60 mH. It can be configured via an Ethernet connection from a PC, making it user-friendly and easily adaptable to existing network configurations.
To facilitate IP address configuration, the device is equipped with a 16-position rotary switch, with each position corresponding to a factory-default IP address. The device can also be set to acquire an IP address automatically from a DHCP server when the rotary switch is set to the “F” position.
For protection against current overload, the SMD-7621 includes a fast-acting, 3.5 A fuse. While it can be used with various third-party motors, National Instruments recommends pairing it with their proprietary NEMA 34 stepper motors for optimal performance. The device’s operation can be monitored through a drive status LED indicator, which alerts users to the current operational status and any faults that may arise.
Despite its Mature Status announcement by National Instruments, the SMD-7621 remains available for purchase and repairs through Apex Waves, ensuring long-term support for users of this sophisticated motion drive device.
