Inhibit Input Polarity SettingTheMID-7604/7602 has a DIP switch that gl obally sets the polarity for the
inhibit input for all axes.D IP switch 10 on the axis 1 DIP switch bank
controlsthis setting. Refer to Figures 1and 3for the location of this switch.
The factorydefault setting of DIP switch 10 is active-low. If the inhibit
inputis active, the axis is inhibited and the yellow status LED (middle row)
illuminatesfor the axis. Table 5 shows the DIP switch setting for the inhibit
inputpolarity s election.
Limit Status LED Polarity SettingTheMID-7604/7602 has a DIP switch that gl obally sets the polarity for the
Limit Status LED. DIP switch 10 on the axis 2 DIP switch bank controls
this setting. Refer to Figures 1 and 3 for the location of this switch.
The factorydefault setting is active-low. Typically,you set the switch to
match your controller’spolarity setting, so that if either the reverse or
forwardlimits for an axis are active, the green status LED (on the bottom
row)for the axis illu minates. This DIP switch alters only the polarity for
the LEDs, and not the actual limit to the motion controller.Table 6 shows
the DIPswitch setting for the Limit Status LED polarity selection.
