Possible counter measures:
•
increasing the filter time constant
•
reducing the changes in the additive position command value
•
increasing the limit values for velocity and acceleration
In the "register controller" synchronization mode all further changes of the
additive position command value are smoothed by a 1
st
order filter. The
time constant of the filter is set in parameter
P-0-0060, Filter time
constant additional pos. command
.
Note:
The status bit "synchronization completed" is set when the
absolute synchronization has been reached and won’t be
cleared even with further changes in
S-0-0048, Position
command value additional
.

"Register controller" synchronization mode
During synchronization in the "register controller" mode the command
values are monitored with regard to
S-0-0091, Bipolar velocity limit
value
and
S-0-0138, Bipolar acceleration limit value
. If the command
values exceed the limit values, the error messages
F2037 Excessive
position command difference
or
F2039 Maximum acceleration
exceeded
are generated.
Possible counter measures:
•
increasing the filter time constant
•
reducing the changes in the additive position command value
•
increasing the limit values for velocity and acceleration
