The definitions of the terms are given. Guess these terms.
| The measure of a load's resistance to changes in velocity or speed. It is a function of the load's mass and shape. |
| The difference in the absolute position of the load for a commanded input when motion is from opposite directions. |
| The difference between the actual result of an input command and the ideal or theoretical result. |
| The instantaneous difference between the actual position as reported by the position feedback loop and the ideal position, as commanded by the controller. |
| The difference between the actual and commanded position after all corrections have been applied by the controller. |
| The maximum magnitude of an input that produces no measurable output when the direction of motion is reversed. |
| The maximum expected difference between the actual and the intended position of an object or load for a given input. |
| The motion control system output compared with the commanded input. |
| The change in velocity per unit time. |
| overshoot | the amount of overcorrection in an underdamped control system. |
| play | the uncontrolled movement due to the looseness of mechanical parts. |
| repeatability | the ability of a motion control system to return repeatedly to the commanded position. It is influenced by the presence of backlash and hysteresis. |
| resolution | the smallest position increment that the motion control system can detect. |
| runout | the deviation between ideal linear (straight-line) motion and the actual measured motion. |
| sensitivity | the minimum input capable of producing output motion. It is also the ratio of the output motion to the input drive |
| settling time | the time elapsed between the entry of a command to a system and the instant the system first reaches the commanded position and maintains that position within the specified error value. |
| velocity | the change in distance per unit time. |
