The machine parameters for HEIDENHAIN TNC 415 include:

1. MP7440, Bit 2 – Allows program to run continuously without waiting for M function acknowledgment, useful for laser cutting machines. Must not be used on milling or boring machines. No PLC positioning, datum shift, spindle orientation, or limit switch during M function output.

2. MP1070 – Controls radial acceleration; effective for operation with lag and feedforward control. Entry range: 0.001 to 5.000 m/s².

3. MP7460 – Defines the angle for constant surface speed in corners. Effective with or without radius compensation. Entry range: 0.0001 to 179.9999°. Typical values: 5° to 15°.

These parameters affect servo positioning, lag, feedforward control, and are important for accurate and smooth machine operation.
