6 All Internal
Monitor‐
ing Error
Minor np During monitoring of an inter‐
nal electronic, an error was
identified.
No action required.
Encoder might recover
automatically.
If error persists even after
clearing, potential hard‐
ware failures are present
and immediate replace‐
ment of the encoder is
required!
5 All Counter
Overflow
Minor np User counter has overrun. Depending on counter use
case.
4 All Critical
Accelera‐
tion
Minor np Acceleration was out of speci‐
fication.
No action required; check
application, reduce acceler‐
ation or check for shock.
3 All Critical
Rotation
Speed
Minor np Rotation speed was out of
specification.
No action required.
Check application for
higher speeds than speci‐
fied. Possibly reduce
speed.
2 All Critical
Supply
Voltage
Minor np Supply voltage was out of
specification.
No action required.
Check encoder power sup‐
ply conditions .
If error persists after ensur‐
ing the input power supply,
potential hardware failures
are present and immediate
replacement of the
encoder is required.

Critical
LED Cur‐
rent
Minor p Monitored sensor behavior or
code disc position out of
specification. Potential cause:
encoder sensor near end of
lifetime, sensor is polluted,
encoder was used outside of
its specification.
Action: SW-reset of the
encoder
Check application for
potential pollution (dust/
brake dust).
If error persists even with
correctly set rotor position,
replacement of the
encoder is required.
