QUICK DETAILS

 

Manufacturers have taken much of the guesswork out of servo tuning (motor-drive-mechanism compensation) of the closed-loop system and determining when a system needs maintenance. Automated or calculated tuning techniques and builtin diagnostic programs help simplify this requirement for the user. In addition, most servo drives can use traditional Step and Direction inputs that have been used to interface to steppers for many years. Servos utilizing this capability are in a position mode that eliminates the potential loss or addition of commanded motor steps.

 

This brings us to one of the most common issues with step motor systems when run on the edge of their capability, the loss and/or addition of motion steps relative to the number of commanded steps. The problem is most noticeable during acceleration and/or deceleration. The loss of steps typically results from too large inertia (affecting acceleration) or higherthan-desirable friction. In contrast, the addition of steps typically results from noise or to too large inertia (affecting deceleration). Due to the accumulation of the additional (+) and loss (-) motion steps, it can take hours before some manufacturing tolerance is exceeded.
