Meaning Cause
OFF OFF No power

Unit switched off

Cable disconnected
ON ON
No connection to another
device
Criteria: no data exchange

Bus disconnected

Master not available or
switched off
ON
Blinking
at 1 Hz
Parametrization fault, no
data exchange
Criteria: data exchange is
correct but the encoder
does not switch to the
data exchange mode

Slave not configured yet
or wrong configuration

A wrong address has
been assigned to the unit

Actual configuration of
the slave differs from the
nominal configuration
OFF ON System failure
Diagnostic data exists,
slave in data exchange
mode
ON OFF
Data exchange, the
encoder is working
properly
Correct operation
