HEIDENHAIN ND 520 - Manual (Page 4)

Datum Setting with a Tool
It is also possible to probe the workpiece with a tool instead of the edge finder. The
functions for datum setting then differ as follows:
•
The tool diameter is automatically taken into account during probing
• The position of the probed workpiece edge is not automatically stored.
Tool diameter:
➤ Enter the tool diameter in operating parameter P25.
To store the position of the workpiece edge when the tool is touching the edge:
➤ Press ENT.
Working with Scaling Factors
The ND 510 and the ND 550 can display the axis traverse lengthened or shortened
by a scaling factor. You enter a scaling factor separately for each axis in the user
parameter P12, then activate the scaling factor function with the user parameter
P11. SCL is highlighted.
Error Messages
Message Cause and effect
Traverse distance with datum setting function (SPEC FCT) is
too short
Incorrect input value
Encoder signal too weak (encoder may be contaminated)
Input frequency too high for encoder input
(will occur for example when traverse speed too high)
Encoder signal to strong
Internal counter overflow
Error while crossing over reference marks
To clear the error message: Switch off the display unit.
Should any of these error codes recur,
contact your HEIDENHAIN service agency.
Offset compensation values for encoder signals have been
erased: contact your service agency.
Compensation values for nonlinear axis error compensation have
been erased
Datums have been erased
Erase the operating parameters.
If all decimal points light up, the measured value is too large or too small.
Set a new datum.
