Appendix F Enhanced Peak Performance
Change the Drive Parameter
Before the drive is capable of accepting a command for the new peak current
ratings, you need to change a drive parameter. This needs to be done only once,
and there are two methods to perform the task.
Sercos IDN Write Instruction
The Sercos IDN write instruction is accomplished by using the Logix Designer
application. Refer to Appendix
E on page 253 for more information on changing
IDN parameter values by using this method.
1. On initialization of the drive, read the INT value of the configuration of
the drive at Sercos IDN P:0:7.
2. If the value of bit zero is zero, latch it and write the new value back to the
drive at the same address, again as type INT.
The Sercos IDN method that uses the Logix Designer application supports
automatic drive replacement (ADR).
