3.5.3 Electronic gear unit with "Flying Saw"
There are two function blocks which allow control of the functions electronic gear unit ("angular
synchronisation") and the sub-function Flying Saw. In addition, various parameters must be set for the
correct execution of the two function blocks in the master and slave frequency inverters. An example of this
is shown in the following table.

{21} "Actual frequency without slip".

NOTE
The actual position of the master MUST be communicated in "Increments" (Inc) format.
