68.02 SYNC GEAR MUL
Defines the numerator for the synchron gear function. The gear function modifies the position
alterations of the synchron position reference value in order to obtain a certain ratio between the
master and follower motion. See also parameter

68.03 SYNC GEAR DIV
Defines the denominator for the synchron gear function. See parameter

68.05 SYNC REF FTIME
Defines the synchron reference filter time. The filter filters synchron reference disturbances, for
example those caused by encoder pulse changes. This parameter is used together with parameter

0...1000 ms
68.06 SYNCFILT DLY LIM
Defines the maximum position difference between the unfiltered and filtered synchron reference. If the
maximum difference is exceeded, the filter output is forced to follow the filter input.
This parameter is used together with parameter
reference disturbances.
The unit depends on parameter

68.07 SYNCHRON MODE
Selects the synchronisation of the follower drive in synchron mode.
