DiagnosCounter
849
Each index contains a counter for fault diagnostics. The
index used depends on the type of encoder in question. In
the event of a fault, the value in the fault counter is
incremented by 10. A correct value causes the value in
the fault counter to be decremented by 1. If a value of 100
is exceeded, the reaction described below occurs. The
parameter is used for early recognition of latent encoder
problems. The type of fault handling described above
does not lead to a fault message until more than 10% of
all values are incorrect!
Alarm A28 is set whenever one of the counters is greater
than 0, and it is cyclically reset when all counters are at 0
again. Display of this alarm and the faults listed below can
be suppressed with P848.
The key to the indices is as follows:
Index 1:
ALARM_NUMBER motor encoders:
SSI alarm bit or EnDat alarm bit
F51:49 in operation, otherwise A19
Index 2:
ALARM_NUMBER external encoders:
SSI alarm bit or EnDat alarm bit
F51:149 in operation, otherwise A21
Index 3:
COMM_ERROR_NUMBER motor encoders:
Protocol error or CRC error
F51:30 in operation, otherwise A19
Index 4:
COMM_ERROR_NUMBER external encoders:
Protocol error or CRC error
F51:130 in operation, otherwise A21
Index 5:
REST LEVEL ERROR_NUMBER motor encoders:
Data line SSI or EnDat has the wrong level
F51:32 in operation, otherwise A19
Index 6:
REST LEVEL ERROR_NUMBER external encoders:
Data line SSI or EnDat has the wrong level
F51:132 in operation, otherwise A21
Index 7:
ADDRESS ERROR_NUMBER moter encoders
F51:34
Index 8:
ADDRESS ERROR_NUMBER external encoders
F51:134
Index 9:
VOLTAGE_ERROR_NUMBER motor encoders:
Operating voltage overloaded
F51:28 and A18
Index 10:
VOLTAGE_ERROR_NUMBER external encoders
Operating voltage overloaded
F51:128 and A20
Index 11:
AMPL_ERROR_NUMBER motor encoders
A/B track: On zero passage of one track, the level of the
other was too low.
F51:29 in operation, otherwise A18
