MSEL (Microstep Resolution Selection)
The Microstepping MForce PowerDrive features 20 microstep resolutions. This setting specifies the number of
microsteps per step the motor will move.
The MForce PowerDrive 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.
