6.3.6 Warnings, errors, diagnosis
There are a number of diagnostic mechanisms that can be used to monitor the measuring system
functions. The table shows an overview of the various options.
The measuring system errors are divided into faults and warnings:
● An error is reported if a malfunction in the measuring system leads to an incorrect position output
● A warning indicates that one or more internal measuring system parameters have been exceeded.
Unlike error messages, warnings do not lead to an incorrect position output.
No warnings are
currently supported.

6.3.6.1 Error codes in signal G1_XIST2
If a measuring system error is present (
G1_ZSW
, bit 15 = 1), instead of the position a 16-bit error code
is transmitted in data bits 2
0
to 2
15
, also see chapter "Format Signal 12: Position value 2, Sensor 1
(G1_XIST2)" on page 113.
The measuring system remains in the error state until the cause of the error has been eliminated and
the error state has been acknowledged with the control word
G1_STW
Bit 15 = 0->1 edge.
If the error cannot be acknowledged, you can try carrying out a device RESET via PNU 972. If the
error still cannot be deleted after this measure, the measuring system must be replaced.

0x1002
Parameterization error
A general parameterization error has occurred. For
visual display and troubleshooting see chapter
"Net status LED" on page 163.
0x1003
Negative preset value
transmitted
When the preset function was executed and the
preset mode = absolute, a negative preset value was
transmitted. Negative preset values are only allowed
in preset mode = relative, see also chapter "Preset
