5.6 Friction compensation (quadrant error compensation)
Reference NC programs
In order to ease the task of the engineer in commissioning the QEC with neural networks,
NC programs containing specimen routines for learning movements and assignments of
QEC system variables (recommended values) are available.
These are the following reference NC programs:
● QECLRNP.SPF
● QECLRNC.SPF
● QECDAT.MPF
● QECSTART.MPF
These NC programs are contained on the diskette of the basic PLC program for the
SINUMERIK 840 D.
Implementing the learning process solely via NC programs has the following advantages:
● Learning can be fully automatic without operator intervention. This is advantageous for
● Learning can take place simultaneously for several axes (up to 4). This significantly
● The traverse movements can easily be adapted to special requirements.

Note
The circularity test is an integral component of HMI Advanced. The commissioning tool
must be used with HMI Embedded.
