MID-7604/7602 Stepper Power Motor Drive User Guide 6 ni.comFront Panel SwitchesFigure 1 shows the front panel of your MID-7604/7602. The DIP switches are shown with thedetachable metal cover plate removed.Figure 1. MID-7604/7602 Front PanelNote Items followed by an asterisk (*) are available on the MID-7604 only.The two rocker switches on the MID-7604/7602 front panel are the AC POWER and ENABLE. Figure 1shows the location of these switches.The AC POWER switch energizes the motor bus (+24 V) and the logic (+5 V) power supplies. Whenswitched on, the green power LED labeled +5 V illuminates. If this LED fails to illuminate, check thepower cord and main input fuse on the front panel.The ENABLE switch enables or inhibits the stepper drivers. If the ENABLE switch is in the inhibitposition (off), the stepper drivers are inhibited, and the yellow LEDs (the middle row of the LED statusarray) and red LEDs (the top row of the LED status array) illuminate for all axes. Refer to the FrontPanel LEDs section of this guide for more information.Note In older versions of the MID-7604/7602, the red status LEDs do not illuminate when theyellow status LEDs illuminate. This behavior only occurs in newer versions of the MID-7604/7602.Both the AC POWER and ENABLE switches can inhibit the stepper drivers. However, as long as theAC POWER switch is on, only the stepper driver output stages are disabled. The remaining circuitryremains active, including the quadrature encoder circuit.Caution You must change the MID-7604/7602 main input fuse on the front panel if you change theline voltage from the factory setting.
