Motion Control Theory
Unit factor can be calculated as described below:
Example 2: Conveyor system
Assume number of pulses generated by one spin of the motor is
8192, the conveyor belt shift 5cm by one spin of the belt pulley, the
gear ratio is 1:2, and the user desired distance unit of measure is
Millimeter then the Unit factor can be calculated as:
Unit factor can be calculated as described below:
Example 3: Linear Motor system with Linear Scale
Take optical resolution at 1 micrometer and distance at millimeter
then the unit factor should be:
