1 What are machine parameters?
A contouring control must have access to specific data (e.g., paths of traverse, acceleration) before
it can execute its programmed instructions.
The machine tool builder provides these data in so-called machine parameters. In addition, machine
parameters can be used to activate functions that are possible with HEIDENHAIN contouring
controls but are required only on certain types of machines (such as automatic tool changers).
The machine parameters are grouped according to function:
Machine parameters Functional group
0 to 999 Measuring systems and machines
1000 to 1399 Positioning
1700 to 1999 Operation with servo lag
2000 to 2999 Eroding
4000 to 4999 Integrate PLC
5000 to 5999 Setting the data interface
6000 to 6199 Probing
7200 to 7399 Display and programming
7400 to 7599 Machining and program run
7600 to 7699 Hardware
If there is more than one input value for a single function (e.g., a separate input for each axis), the
parameter number is provided with indices.
Example:
MP330 Grating period
MP330.0 Grating period for axis X
MP330.1 Grating period for axis Y
MP330.2 Grating period for axis Z
MP330.3 Grating period for axis 4
MP330.4 Grating period for axis 5
The indices are assigned to the corresponding axes according to a fixed pattern. For example, if
entry is only possible in axis 4, then only index 3 will appear.
1.1 User parameters
The MOD function "User Parameters" permits the control operator to easily access and change
certain machine parameters. The machine tool builder can define up to 16 different machine
parameters as user parameters with MP7330 (see Chapter "Machine Adjustment", Section "Display
and operation").
