Radius display for X axis active
The ND 530 display unit for lathes is designed for use with two HEIDENHAIN linear
encoders with sinusoidal output signals.
The linear encoders have one reference mark or several (preferably distance-coded)
reference marks. When a reference mark is crossed over, a signal is generated which
identifies that position as a reference point.
After switch-on, crossing over the reference marks restores the relationship between
axis slide positions and display values last established by datum setting. With encoders that have distance-coded reference marks, this requires a traverse of no more
than 20 mm.
Switch-On

Ent...CL
5 , 6 9 7
If you do not wish reference mark evaluation, press CL instead of ENT.
Turn on the display unit (switch located on rear panel).
• Display shows .
• REF blinks.
Switch on reference mark evaluation.
• The display shows the value last assigned to the reference
mark position.
• REF glows.
• The decimal point blinks.
Cross over the reference mark.
Move the axis until the display becomes active and the decimal
point stops blinking.
The display unit is now ready for operation.
Datum Setting
The datum setting procedure assigns a specific axis position to the associated display
value. For example, you can set the workpiece face to Z = 0 mm and a shoulder on
the workpiece to its associated X coordinate.
You can set two separate datum points.
Select datum point 1 or 2.
Enter a numerical value, such as 40.
4 0
Confirm your entry.
You can switch from one datum point to the other at any time.
Use datum point 2 if you want to display incremental dimensions.
Radius Display for the X Axis
There are two ways to switch the X axis from diameter to radius display:
• Operating parameter or
• The Rx key.
When Rx lights up the radius display is active.
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
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.
To clear error message :
When you have removed the cause of the error,
➤ press CL.
Non-linear Error Compensation
To work with the non-linear error compensation it is necessary to
• activate the function via the operating parameter P40.
• traverse the reference marks after switching on.
• enter the compensation values in the table.
For every axis compensation values can be entered over 16 compensation points. To
determine the compensation values with a comparator system from HEIDENHAIN,
such as VM 101, you must select the REF display.
Selecting the Compensation Value Table
➤ Select the operating parameter P00 and enter the code number 105 296. Use
the following keys for the entries:
Key Function
MOD Save input value and select next input parameter.
1 / 2 Save input value and select preceding input value.
R+ Select REF display.
ENT • Save entry.
• Exit compensation value table.
CL • Delete entry.
• Delete all compensation values.
➤ Enter the parameters and compensation values as follows:
Display Entry
Enter the axis to be compensated, e.g. X.
Enter the axis causing the error, e.g. X, i.e. X = F(X).
Enter the datum on the axis causing the error.
Enter the distance of the compensation points on the errorcausing axis, e.g. 14 (= 2
Minimum input value: 10 (= 1.024 mm)
Maximum input value: 23 (= 8388.608 mm)
Select compensation point No. 1. The compensation point
number can be seen while pressing the MOD key. After letting
go of the MOD key the coordinates of the selected compensation
point can be seen in the upper line. Enter the compensation value
in the lower line.
Enter all following compensation points.
Delete all compensation values:
Display Entry
Press key CL.
Press key ENT. Compensation values are deleted.

Operating Parameters
User Parameters
User parameters are operating parameters that can be changed without entering the
codes: P00 to P12
Axis assignment
Parameters which are entered separately for each axis have axis codes:
"1" signifies the X-axis, "2" the Z-axis. A point separates the axis code from the
parameter number. In the operating parameter list, these parameters are set off
with a superscript "A", the parameter for the X-axis (e.g. ) is in the list.
You select axis-specific operating parameters with the orange arrow keys.
To call the operating parameter list:
➤ Press MOD.
To go directly to a certain operating parameter:
➤ Press and hold CL, then press the first digit of the parameter number.
➤ Release both keys and enter the second digit of the parameter number.
Protected Operating Parameters
In order to change protected operating parameters, the code number 95 148 must
be entered via P00 Code: They remain accessible until the position display is
switched off.
To page through the operating parameter list:
➤ Page forward: press MOD.
➤ Page backward: press the 1 / 2 key.
Any changes are automatically activated when you resume paging.
To change a parameter setting:
➤ Change the value with the minus key, or
➤ Enter the desired value directly, e.g. for P12.
To correct an entry:
➤ Press CL.
To exit the operating parameters:
➤ Press ENT.
This activates all changes made.
