67.03 INTERPOLAT MODE
Selects whether the synchronisation reference selected by parameter
interpolated or not. This function can be used to smooth out short breaks in the reference.
(0) NONE
(1) INTERPOLATE
67.04 INTERPOLAT CYCLE
Interpolation cycle for synchronisation reference. Used if the drive does not receive a changing
position reference from the synchronisation reference source. During the cycle, the drive calculates
an internal synchronisation position reference according to the previous cycle reference delta. After
the cycle, the drive updates the new value to signal

Interpolation is not used. The synchronisation reference is reflected
directly by actual signal
The synchronisation reference is interpolated as shown in the diagram
below.
The synchronisation reference is sampled at intervals defined by
