Changing the Default IDN Parameter Values
Introduction
This appendix provides a procedure, specific to the Kinetix 6000(SERCOS)
drive systems, for changing IDN parameter values to non-default values when
your application does not match the default configuration.
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 128 - IDN Instruction Format in the IEC Standard Document
There are default parameters in the Logix-to-Kinetix 6000 drive product
structure you can reconfigure when the default configuration does not match the
Integrated Architecture machine configuration.
Using this procedure, you can change the Additional Bus Capacitance value in
common-bus configurations.
