• The cyclic correction function calculates correction value of 0.458 revolution
and corresponding superimposed movement is activated with the given profile
• After correction, the drive receives another latch at 22.7 seconds which requires
only a small correction.

Transfer of latching data over drive-to-drive (D2D) link
With the cyclic correction function, you can transfer master latch 1 data (parameter
Latch1 position) along the D2D to follower drive. This helps to reduce wiring as
each drive needs only its own latch connection.
You can activate the function through parameter 86.57 . Parameter 61.1 or 61.2 or
61.3 needs to be set to D2D velocity . Latch 1 rising edge is transferred from master
to follower as a pulse marker as part of D2D velocity data instead of actual data.
This is performed whenever it is necessary and when D2D velocity is selected as
transferred data.
The status of this function is shown by parameter 86.1 Axis status, Bit 8.
