Current-Loop Gains: Ixx61, Ixx62, Ixx76
The current-loop tuning can be performed as in any Turbo PMAC digital current loop setup. The
PMACTuningPro2 automatic or interactive utility can be used to fine-tune the current loop gains.
Ixx61=0.005, Ixx62=0, and Ixx76=0.05 is a good/safe starting point for interactive current-loop
tuning. Typically, an acceptable current-loop step response would look like the following:

Number Of Counts Per Revolution (Stepper Motors)
With a count equal to a micro-step, and 512 micro-steps per 1.8-degree full step (2048 per
cycle), you should expect to see 360*512/1.8= 102,400 counts per revolution of the motor.

Note
Some stepper motors have unconventional specifications making
top speeds unattainable with the basic micro-stepping technique.
Adjusting the direct current on the fly might be necessary (i.e.
using open servo).
