Microstepping Selection
The MID-7604/7602 uses bipolar chopper, two-phase microstepping drivers with a broad range of
microstep rates. The factory default setting is 10-times microstepping (2,000 steps/rev with standard
1.8º stepper motors). Table 2 shows the DIP switch settings for all possible microstep settings. DIP
switches 6 through 9 control the microstep rate on a per-axis basis.
