The NI MID-760x provides stepper motor control from the NI 7330, 7340, and 7350 controllers. The MID-7650 MID-7650 provides DC-brush servo motor control from NI 7340 and 7350 controllers. Because the MID-760x and the MID 7650 have all the required motion drive and motion I/O signals, they offer all the features of a universal motion interface wiring module with the enhancements of a powered motor drive in a single product. The NI MID power drives connect to motion controller boards through a single-shielded cable that transfers all motor commands, as well as motion I/O control and feedback signals. The MID-7604 MID-7604 and MID-7602 MID-7602 are 4-axis and 2-axis stepper motor drive units, respectively. The MID-7654 MID-7654 and MID-7652 MID-7652 are 4-axis and 2-axis DC-brush servo motor drive units, respectively.

This optimized system wiring design simplifies motion component selection. High-Efficiency Architecture The MID-760x power drives incorporate an efficient bipolar chopper architecture that converts step and direction control signals into winding currents for 2-phase stepper motors. The MID-765x power drives incorporate an efficient servo amplifier architecture that converts analog control signals into winding currents for DC-brush motors. The pulse width modulation driver technology in the MID-765x accurately controls motor winding current, while reducing motor heating, lowering ripple current, and improving overall motor performance. Active fan cooling provides optimal motion power drive operation. Motor Drive (A) 0.2 to 1.4 0.2 to 1.4 0.8 to 5 continous 10 peak 0.8 to 5 continous 10 peak Figure 1.

Please refer to your controller specifications to determine overall system specifications. General (All MID 76xx drives) Some signals define compatibility as pass-through. This means the MID 76xx may have passive filtering on these signals, but the signals do not affect the voltage range. Consult your motion controller specifications to determine allowable voltage range and logic level compatibility of the signal. Inputs. Differential input threshold. Single-ended input threshold.
