Data Output and Display Freeze by Output Signal
The effect of a signal for measured value output is defined in operating parameter
P55.
➤ Concurrent display: No output value freeze. The output describes the current
measured value ( ).
➤ Frozen display: The output value is frozen and is updated with each signal for
measured value output ( ).
➤ Frozen/concurrent display: The output value freezes only as long as the signal is
present ( ).
P23 defines whether the display shows the current measured value ( ) or the
value at the data output ( ).

Message Cause and Effect
Last measured value not yet latched 1)
Attempt to reset to zero or preset not permissible.
The display is not reset or preset.
Incorrect input value
Overflow caused by external preset
Value entered cannot be displayed
Overflow, trigger limit 1
Overflow, trigger limit 2
Overflow, lower sorting limit
Overflow, upper sorting limit
Encoder signal too weak 1) (encoder may be contaminated)
Input frequency too high for encoder input 1)
(will occur for example when traverse speed too high)
Internal counter overflow 1)
Error while crossing over reference marks 1)
To clear the error message: Switch off the display unit.
Should any of these error codes recur, contact your HEIDENHAIN
service agency.
Erase the operating parameters.
If all decimal points light up, the measured value is too large or too small.
In this case, set a new datum or retract.
If all sorting indicators light up, this means that the upper sorting limit is less than
the lower limit.
1) These errors are significant for a connected device. The error signal (pin 19) at the
D-sub connection EXT is active.
