Description Required error handling
ENC_ST3
(adr. 43h)
1 EEx37 Critical
Rotor
Position
Critical p Only for capacitive encoders:
Rotor position out of specified
tolerance.
Attention! A proper and cor‐
rect mounting of the encoder
has to be ensured, otherwise
proper functionality can’t be
guaranteed!
Potential cause: mechanical
shocks, improper encoder
mounting
The drive system must be
placed in a safe condition,
because with distorted sig‐
nals no proper functionality
can be guaranteed
Action: SW reset of the
encoder.
Upon reset, the Rotor Posi‐
tion will be checked again.
If error bit is set, check
application and encoder
mounting.
If error persists even with
correctly set Rotor Position,
replacement of the
encoder is required!
0 All Critical
Tempera‐
ture
Minor np Encoder temperature was out
of the specification
No action required;
check application for poten‐
tial motor/encoder cool
down
ENC_ST4
(adr.44h)
3 All File
access
error
Minor np Error when accessing a file in
EEPROM.
Potential cause: may indicate
EMC problems or corrupted
file system due to previous
power-down during write
access or just simply incorrect
access parameters.
Check and retry command.
2 All Resource
access
error
Minor np Error when accessing an inter‐
nal resource.
Potential cause: may indicate
EMC problems, excessive
number of EEPROM write
cycles or wrong timing of
power cycle vs. EEPROM write
access or just simply incorrect
access parameters.
Check and retry command;
check resource access
sequence.
1 All Access
denied
Minor np Access to a resource was
denied.
Check and retry command;
check access user level.
0 All Invalid
access
Minor np Invalid argument/command
of a resource access.
Potential cause: drive
firmware fault or internal sig‐
nal transmission fault (due to
EMC) or just simply incorrect
access parameters.
Check and retry command;
check drive firmware.
ENC_ST7
(adr. 47h)
0-7 All User

warning
Minor np Depending on user customiza‐
tion (see chapter 9.8.5).
Depending on configura‐
tion.
P – bit is set again in slave, after every clearing by master (acknowledgement)
Np- bit is cleared in slave after clearing by master (acknowledgement)
