Microstep Selection
The microstepping drivers in your stepper nuDrive have a DIP switch for
setting the microstep ratio. Table 5 shows the DIP switch settings for all
possible microstep configurations.
Stepper Motor Configurations
This section describes the various industry-standard winding
configurations for stepper motors and shows how to connect them to a
stepper nuDrive. The nuDrive is compatible with all configurations of
two-phase stepper motors.
Note The stepper nuDrive is not compatible with five-lead unipolar stepper motors or
five-phase stepper motors; the stepper nuDrive is only compatible with 2-phase type
stepper motors.
