System manual CECX / Incremental encoder interface module CECX-C-2G2
CECX-II 27-18
The application has to provide the actual values, which are then read out
via the standard interface.
This way application tests can be conducted without the incremental en-
coder being connected.
27.7 Operating behavior
27.7.1 Response to sensor failure
This monitor checks the signal level of transducers with 5 V diff. interface.
Both, the open signal lines as well as the short-circuited transducer lines
are identified.
27.7.2 Behavior at transducer error
If the Zero pulse monitor is activated through configuration of the number of
increments per rotation, the CECX-C-2G2 will internally monitor the number
of pulses between two Zero pulses. If the number deviates, an error will be
triggered.
27.7.3 Behavior at short circuit of transducer supply
Both outputs for the transducer supply are sustained short-circuit proof and
protected against overload.
27.7.4 Monitoring track errors
If the maximum input frequency is exceeded, or if the edges of the incre-
mental encoders are too close to one another (e.g. if there is no 90° phase
difference between the tracks), this will be identified as error and output as
such.
