Warnings - IFM Electronic RNX-13 Bit Handbuch

3.4.9 Warnings

Warnings indicate that tolerances for certain internal parameters of the encoders have been exceeded.
Contrary to alarms no faulty position values are expected in case of warnings.
Octets 20 and 21 of the diagnostic function indicate the status of the warnings. If a warning is set, the
Ext_Diag bit in the diagnostic function is logically set to 1 until the warning is reset. All warnings are
deleted when the diagnostic message of the encoder has been read. If the tolerances are however still
exceeded, the warning is activated again. The warning "Maximum operating time exceeded" (bit 4) is not
activated before the system is switched on again.
Not every encoder supports every warning. We refer to the diagnostic information "3.4.10 Unterstützte
Warnungen" (see: 0) for information on the supported warnings.
