System of Units
Selecting a unit
In the parameter assignment user interface of the cam controller, you can select a
specific unit for inputting and outputting data (default: mm).
You can also select the following units:
•
Millimeters, inches, degrees and pulses.
Note
If you change the unit in the parameter assignment user interface, the values are
calculated in the new system. This can lead to rounding errors.
If you change the unit using the machine data, the values are not recalculated
automatically.
If the unit is changed from or to “pulses”, the cam processing is deactivated and
the axis is no longer synchronized.
