Encoder emulation following error
No.

Encoder emulation following error
configurable
Cause
The critical frequency for encoder emulation was exceeded (see
manual) and the emulated angle at [X11] was no longer able to
follow. Can occur if very high numbers of lines are programmed for
[X11] and the drive reaches high speeds.
Measure
Check whether the parameterised number of lines may be too
high for the speed being represented.
Reduce the number of lines if necessary.

No synchronisation via field bus
configurable
Cause
When activating the interpolated position mode, the controller
could not be synchronised to the fieldbus.
–
The synchronisation messages from the master may have failed
or
–
the IPO interval is not correctly set to the synchronisation inter
val of the fieldbus.
Measure
Check the settings for the controller cycle times.

Field bus synchronisation error
configurable
Cause
–
Synchronisation via fieldbus messages during ongoing opera
tion (interpolated position mode) has failed.
–
Synchronisation messages from master failed?
–
Synchronisation interval (IPO interval) parameterised too
small/too large?
Measure
Check the settings for the controller cycle times.
