Changing the Default IDN Parameter Values
This appendix provides a procedure, specific to the Kinetix 6200 (sercos) drive
systems, for changing IDN parameter values to non-default values when your
application does not match the default configuration. The procedure also applies
when one or more Kinetix 6000M IDM systems are present.
Before You Begin The Logix processor contains a motion planner that sends real-time and non real-
time data to the drive. This drive communication is performed via a set of sercos
interface telegrams. Each telegram has an identification or Ident (IDN) number.
All parametric data, such as scaling and loop gains, and real-time loop closure
information is configured this way.
Table 115 - IDN Instruction Format in the IEC Standard Document
There are default parameters in the Logix-to-Kinetix 6200 drive product
structure you can reconfigure when the default configuration does not match the
Integrated Architecture™ machine configuration.
The drive functions you can change by using this procedure include:
• Additional bus capacitance in common-bus configurations
– With RSLogix 5000 software, version 20.00 or greater, you can
configure bus capacitance values from I/O configuration>Sercos
module>Drive module properties>Power tab (refer to
Chapter 6 )
• Digital input assignments for I/O configurations

IMPORTANT IDN values return to default settings whenever the sercos ring phases up. If
your program includes a message instruction to change default IDN values, you
must re-execute that instruction during phase-up to maintain those values.
