Increasing the differential gain (KD) lowers the frequency at which it has more impact than the proportional factor (KP). This introduces positive phase shift in the proportional range to help offset the negative phase shift from the integration factor KI, thereby improving the phase margin and reducing the ringing. It has the undesirable effect, however, of increasing the high frequency gain, making the servo more noise sensitive and encouraging the undesirable effects of natural resonances.

Changing the integration factor (KI) has the impact shown below. Not only does it affect the low frequency gain, but it changes the frequency at which the proportional factor (KP) becomes effective. It would be most desirable to raise KI as high as possible, but the higher it gets, the more negative a phase shift is introduced in the proportional range where the servo bandwidth normally ends up. This reduces the phase margin of the servo, causing overshoots and ringing as described in an earlier column.

Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called "phases". By energizing each phase in sequence, the motor will rotate, one step at a time.
With a computer controlled stepping you can achieve very precise positioning and/or speed control. For this reason, stepper motors are the motor of choice for many precision motion control applications.
Stepper motors come in many different sizes and styles and electrical characteristics. This guide details what you need to know to pick the right motor for the job.
