Customized Measurement Units
You can choose your own measurement units, with the Length field allowing a maximum of 5 characters to be entered. For example, degrees.
You must, however, choose the position unit to be such that the resolution value (Distance / No. of points) is between 0.5 and 1,000. The speed unit is calculated using the formula:
Speed unit = Position unit * 1000 / min
NOTE: You cannot choose the speed unit which results from the formula. You can however modify the text. For example,
Either an incremental encoder capable of 500 points per turn. The distance corresponding to 1 turn is 2mm, or 2000 microm. The resolution is expressed by the ratio of 2000 / 500 (thus in microm). The resulting speed unit will be mm/min (see table below).
