Limit Status LED Polarity Setting
The MID-7604/7602 has a DIP switch that globally 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 factory default setting is active low. Typically, you set the switch to
match your controller’s polarity setting, so that if either the reverse or
forward limits for an axis are active, the green status LED (on the bottom
row) for the axis illuminates. This DIP switch alters only the polarity for
the LEDs, and not the actual limit to the motion controller. Table 6 shows
the DIP switch setting for the Limit Status LED polarity selection.
Back Panel Connector Wiring
Motor Power Terminal Blocks
Each axis on the MID-7604/7602 has a separate 5-position removable
screw terminal block for motor power 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 is active low.
