11.5.2 Factors
Position factor
The position factor is the relation between the user unit and the internal position unit
(steps).
The position factor is automatically calculated when the feed constant (Object 6092h)
and gear ratio (Object 6091h) are set.
Example:
A MIS232 Motor with a 3.5:1 gear box is connected to a belt drive. The diameter of the
drive wheel is 12.4 cm.
The unit of position is required to be in millimetres.
The perimeter of the drive wheel is 389.56mm (124mm*pi)
The parameters should be set as follows:
