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.
