4 Machine Parameters
4.1 What Is a Machine Parameter?
A contouring control must have access to specific data (e.g., traverse distances, acceleration) before
it can execute its programmed instructions. You define these data in so-called machine parameters.
In addition, machine parameters can be used to activated certain functions, which are
possible with HEIDENHAIN contouring controls, but are required only on certain types of machines
(e.g. automatic tool changing). The list of machine parameters is not numbered in sequence but is
divided into groups according to function.
Machine parameter Functional Group
10 to 999 Encoders and Machines
1000 to 1399 Positioning
1400 to 1699 Operation with Velocity Feedforward
1700 to 1999 Operation with Servo Lag
2000 to 2999 Integrated Closed-Loop Speed and Current Control
3000 to 3999 Spindle
4000 to 4999 Integral PLC
5000 to 5999 Data Interface
6000 to 6199 3-D Touch Probe
6200 to 6299 Digitizing with Triggering Touch Probe
6500 to 6599 Tool Measurement with Touch Trigger Probe
7100 to 7199 Tapping
7200 to 7349 Display and Operation
7350 to 7399 Colors
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 that are permanently assigned to the corresponding
axes: Index zero is always axis X, index one is always axis Y, etc.
Example:
MP1010.0-3 Rapid traverse
MP1010.0 Rapid traverse for axis X
MP1010.1 Rapid traverse for axis Y
MP1010.2 Rapid traverse for axis Z
MP1010.3 Rapid traverse for axis 4
Other machine parameters function as on/off switches for specific functions. These machine
parameters are bit-coded. Each bit is assigned to either an axis or a function.
