MSEL (Microstep Resolution Selection)

The MDrivePlus Microstepping features 20 microstep resolutions. This setting specifies the number of microsteps per step the motor will move.

The MDrivePlus uses a 200 step (1.8°) stepping motor which at the highest (default) resolution of 256 will yield 51,200 steps per revolution of the motor shaft.

See Table 2.3.2 for available Microstep Resolutions.
