The SGE modification timer did not expire within
the time of the control timer (i.e. too many switching
operations in SGEs).

Different status of user enable from drive and NCK
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
The user enable has been specified for an axis
which is
– already referenced
– not yet referenced
The "pulses are deleted" signal is already active on
test stop selection
An error was detected on the cyclic check of the
SGAs.
If the drive releases a breakdown in communica-
tion, either the PLC or the NC has broken down.
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.
