Position
Cross-
check
Error
Critical p Only for safety encoders and
HF2DSL coupler.
Internal cross-check of safe
absolute position has failed.
In case of non-safe encoders,
this bit is always ‘0’.
Potential cause(s): hardware
faults; for linear encoders:
alignment fault read-head/
measure.
The drive system must be
placed in a safe condition.
Action: SW-reset of the
encoder.
EEx37 Not

mented.
Always ‘0’

3 All Multi-turn
Vector
Length
Error
Critical p Encoder has detected an
invalid multi-turn sensor sig‐
nal vector length.
Potential cause(s): excessive
mechanical stress
The drive system must be
placed in a safe condition.
Action: SW-reset of the
encoder
2 All Multi-turn
Sync
Error
Critical p Multi-turn sensor synchroniza‐
tion was erroneous.
Potential cause(s): encoder
reached end of lifetime, hard‐
ware faults, magnet (clip)
faults or gear wear-out.
NOTE: A multi-turn synchro‐
nization diagnostic cannot
reliably detect gear synchro‐
nization faults over extended
time. After first indication of
this fault gear synchronization
can wear out even more and
result in undetected false
position output.
The drive system must be
placed in a safe condition.
Action: immediate replace‐
ment of encoder
1 All Multi-turn
Ampli‐
tude
Error
Critical p Invalid multi-turn sensor sig‐
nal amplitude.
Potential cause(s): magnetic
disturbances, multi-turn sen‐
sor defects, loss of multi-turn
magnets or errors in multi
turn parameters.
The drive system must be
placed in a safe condition.
Action: immediate replace‐
ment of encoder
0 All Single-
turn Error
Critical p Initialization of single-turn
sensor was erroneous, or the
encoder could not measure
absolute single-turn position.
This results in an overall
invalid encoder position.
Potential causes: hardware
failures or external shocks.
The drive system must be
placed in a safe condition.
Action: SW-reset of the
encoder
