Parameter matching between the CNC and the Sercos drive
6.1 Parameter matching between the CNC and the Sercos drive
Some CNC and drive parameters must be set accordingly (matching each other) to ensure proper
system performance. 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 parameters to
ensure that they match.
Understanding the parameter matching table.
The table indicates which CNC parameters are involved in parameter matching as well as a the drive
parameters that are affected. The different columns of the table have the following meanings.
CNC List of CNC machine parameters.
DRIVE List of drive parameters that are equivalent to each CNC parameter.
Feedback Indicates whether or not writing the parameter at the drive depends on the type of
axis feedback, either internal or external.
The CNC matches the parameters when the drive is an ACSD.

CNC DRIVE Feedback Remarks
FBACKDIF (P100) PP5 External If 2nd drive feedback
INPREV (P87) NP121 If INPREV, OUTPREV
and PITCHB are other than 0.
It affects all the sets.
OUTPREV (P88) NP122 If INPREV, OUTPREV and PITCHB are other than 0.
It affects all the sets.
PITCHB (P86) NP123 If INPREV, OUTPREV and PITCHB are other than 0.
It affects all the sets.
I0TYPE (P52) PP115 External It writes bits 0, 1, 3.
PV200 If 2nd drive feedback and I0TYPE =1 or 2.
It writes 0.
I0CODI2 (P69) NP165 If 2nd drive feedback and I0TYPE =1 or 2.
I0CODI1 (P68) NP166 If 2nd drive feedback and I0TYPE =1 or 2.
ABSOFF (P53) PP177
PP178
Internal
External
If 1st drive feedback.
If 2nd drive feedback.
If axis parameter DRISET(P91) is other than 0, drive parameters NP121, NP122 and NP123 are
updated with the set indicated in that axis machine parameter.
