DOK-INDRV*-MP*-02VRS**-FK01-EN-P
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.

Fig. 7-73: "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
