Parameter matching between the CNC and the Sercos drive.

Some parameters of the CNC and of the drive must be set equivalently to ensure proper
system operation. While initializing the Sercos ring, on CNC power-up and when validating
the machine parameters of the axes and spindles, the CNC updates at the drives the value
of the parameters necessary to ensure that they are equivalent.

The CNC does not match the parameters when the drive is an ACSD.
Parameter matching and speed ranges (gears).
The number of parameter sets to define the speed ranges (gears) may be different at the
CNC and at the drive. If there is a parameter set at the CNC, the parameter matching updates
parameters NP121, NP122, NP131 and NP133 of each set of the drive with the values
defined at the CNC. The parameter matching will save the CNC's default set values in the
rest of the sets of the drive.
Understanding the parameter matching table.
The table indicates which CNC parameters are involved in parameter matching as well as
the drive parameters that are affected. The different columns of the table have the following
meaning.
