Error
Critical
p
The position drift was not
properly compensated.
Will lead to a VPOS-error.
The drive system must be
placed in a safe condition.
Action: SW reset of the
encoder.

Available only for safety
encoders.
Indicates that a diagnostic
test has been requested by
application.
Action required as detailed

Accelera‐
tion Over‐
flow Error
Minor
np
Two subsequent fast position
values were too far apart for
valid DSL transmission; too
high shaft acceleration or
shaft was turned while the
link was not active.
No action required.
Fault is not permanent and
encoder recovers automati‐
cally. This error will likely
will lead to other errors.
Possible causes: mechani‐
cal shocks or hardware
faults.
If the error persists, there
is probably a general hard‐
ware or mechanical failure.
Inform customer service.

Reset
Indication
Minor
np
Indicates that the DSL proto‐
col has been reset and a new
connection was established.
Serves a base indication for
the start of the communica‐
tion (like LINK). If not set after
an encoder reset, no status
registers can be relied upon!
Action: successful clearing
is required.
If this indication persists
(bit is set), it is likely that
the encoder was again
resetted. Check connection
or supply of the encoder.
Before the successful
clearing of this indication,
no other ENC_ST informa‐
tion can be relied upon!
