7 Machine Data
7.1 NCK machine data for ShopMill
NCU load
7-40
With the softkey "Actual=setpoint" you adjust incorrect values to the minimum
requirements of ShopMill if you confirm the following question with "OK".
If the actual value is too low, for example, the value of the machine data is set to
the lowest setpoint. For bit masks only the missing bits are set.
Note
The file SIEMENSD.RTF or SIEMENSE.RTF provides a list with the required
settings of the ShopMill machine data. You are advised to print these out. You
can then check and if necessary correct the specific values more conveniently.
Note
Please note that the machine data record also contains machine data for
configuring the memory.
An exact description of all NC machine data can be found in:
