© National Instruments Corporation 13 MID-7604/7602 Stepper Power Motor Drive User GuideLimit Status LED Polarity SettingThe MID-7604/7602 has a DIP switch that globally sets the polarity for the Limit Status LED. DIPswitch 10 on the axis 2 DIP switch bank controls this setting. Refer to Figures 1 and 3 for the locationof this switch.The factory default setting is active low. Typically, you set the switch to match your controller’s polaritysetting, so that if either the reverse or forward limits for an axis are active, the green status LED (on thebottom row) for the axis illuminates. This DIP switch alters only the polarity for the LEDs, and not theactual limit to the motion controller. Table 6 shows the DIP switch setting for the Limit Status LEDpolarity selection.Back Panel Connector WiringMotor Power Terminal BlocksEach axis on the MID-7604/7602 has a separate 5-position removable screw terminal block for motorpower wiring. Figure 4 shows a typical stepper motor configuration pin assignment.Note The dotted loop indicates a shielded cable. A line above a signal indicates that the signal isactive low.Figure 4. Typical Full-Coil Stepper Motor (2-Phase Type) Terminal Block Pin AssignmentCaution The stepper motor connectors on this drive are energized when the unit is powered on.Disconnect the MID-7604/7602 unit from the power outlet before connecting wires to ordisconnecting wires from the stepper connectors. Strip back the insulation of the stepper wires to thestepper connectors no more than 7 mm. Failure to do so could result in electric shock leading toserious bodily injury or death.Table 6.
