Cause
The voltage monitor signals an overvoltage
fault on the module.
The number of actual value telegrams from
the power unit that have failed has ex-
ceeded the permissible number.
The measured zero mark distance does
not correspond to the parameterized zero
mark distance.
For distance-coded encoders, the zero
mark distance is determined from zero
marks detected pairs. This means that if a
zero mark is missing, depending on the
pair generation, this cannot result in a fault
and also has no effect in the system.
The 1.5 x parameterized zero mark dis-
tance was exceeded.
Serial communication protocol transfer
error between the encoder and evaluation
module.
The absolute encoder fault word supplies
fault bits that have been set.
The encoder sends a set error bit via the
serial protocol.
For a square-wave encoder (bipolar, dou-
ble ended) signals A*, B* and R* are not
inverted with respect to signals A, B and R.

Remedy
Check the 24 V power supply.
•
Replace the module if necessary.
•
Replace the module if necessary.
Check that the encoder cables are routed
•
in compliance with EMC.
Check the plug connections
•
Replace the encoder or encoder cable
•
Check that the encoder cables are routed
•
in compliance with EMC.
Check the plug connections.
•
Replace the encoder or encoder cable.
•
Check the encoder cable and shielding
•
connection.
Replace the encoder cable/encoder.
•
Check the encoder cable connection and
•
make sure the cables are routed in com-
pliance with EMC.
Check the motor temperature.
•
Replace the motor/encoder.
•
Refer to F31111.
Check the encoder and cable and the
•
connection of them.
Does the encoder supply signals and the
•
associated inverted signals?
