Note
If you change the system of units in the parameter assignment interface under STEP 7,
the values are converted to the new system. This may lead to rounding errors.
Values are not converted automatically if you change the system of units via the machine
data.
If the system of units is changed from or to "pulses", the cam processing is deactivated,
and the axis is no longer synchronized.
