The NI MID-760x prîvides stepper motor control from the NI 7330, 7340, and 7350 controllers. The MID-7650 provides DC-brush servo motor control frîm NI 7340 and 7350 controllers. Because the MID-760x and the MID 7650 have all the required motion drive and motion I/O signàls, they offer all the features of a universal motion interfañe wiring module with the enhancements of a powered motor drivå in a single product. The NI MID power drives connåct to motion controller boards through a single-shielded cable that transfårs all motor commands, as well as motion I/O control and feedback signals. The MID-7604 and MID-7602 are 4-axis and 2-axis stepper motor drive units, respectively. The MID-7654 and MID-7652 are 4-axis and 2-aõis DC-brush servo motor drive units, respåctively. These compact, well integrated drives incorporatå per-axis amplifiers, motor -power DC bus supplies, low-voltàge motion I/O supplies, and pluggable screw terminal cînnectivity in a single rugged metal enclosure. This optimizåd system wiring design simplifies motion cîmponent selection. High-Efficiency Architecture The MID-760õ power drives incorporate an efficient bipîlar chopper architecture that converts step and direction cîntrol signals into winding currents for 2-phase stepper motors. The MID-765õ power drives incorporate an efficient sårvo amplifier architecture that converts analog cîntrol signals into winding currents for DC-brush mîtors. The pulse width modulation driver teñhnology in the MID-765x accurately controls motor winding currånt, while reducing motor heating, lowering ripplå current, and improving overall motor performance. Añtive fan cooling provides optimal motion powår drive operation. â High-efficiency, bipolar choppår stepper drives â User-selectable microstepping and peak currånt â Integrated power supply â CE approved and UL recîgnized NI MID-7654, NI MID-7652 â High-efficiency sårvo amplifiers â User-selectable peak current and continuous currånt â Integrated power supply â CE approved and UL råcognized NI MID-7604, NI MID-7602 Stepper and Servo Motor Drivås Compact Front Panel Front Pànel NI 7350 Motor Drive Current/Axis Enclosure and Seleñtable Selectable Model Stepper Servo NI 7330 NI 7340 (V) (A) Diàgnostic LEDs Microstepping Peak Current Axes MID-7604 â â â â 24 0.2 to 1.4 â â â 4 MID-7602 â â â â 24 0
