1000 Control timer expired The SGE modification timer did not expire within
the time of the control timer (i.e. too many switching
operations in SGEs).
e.g. contact problems (loose con-
tact)
1001 Control timer initialization error The SGE modification timer did not start the control
timer.

1002 User enable timer expired Different status of user enable from drive and NCK –
1003 Reference tolerance violated The comparison of stored standstill position and
current position has a greater deviation than speci-
fied in MD 4252*: actual value tolerance (referenc-
ing) or MD 1344

1004 Plausibility violation of user
enable
The user enable has been specified for an axis
which is
– already referenced
– not yet referenced
–
1005 Pulses already deleted on test
stop selection
The ”pulses are deleted” signal is already active on
test stop selection
Test stop selection on pulse en-
able error during wiring of the
”pulses are deleted” SGE
1006 Error on SGA forced dynamic
response
An error was detected on the cyclic check of the
SGAs.
–
1007 Breakdown of the communi-
cation between PLC and drive
If the drive releases a breakdown in communica-
tion, either the PLC or the NC has broken down.
1008 Erroneous data transfer bet-
ween PLC and drive
The data transfer of the SGEs/SGAs between PLC
and drive is guaranteed by a checksum. In the
event of an error, the calculated checksum does
not coincide with the transferred checksum. If the
stop is released by the drive, either the PLC or the
NC has broken down.
Note:
If the value 12 is stored in this value, the cross–comparison has detected a difference in the MD for lower limit SE1 in the NCK
and drive monitoring channel.
