Free objects

Introduction
In the object directory you have the possibility of using "free objects" for process data in the
range from 5800 hex to 5FFF hex (also refer to Chapter "CANopen object directory").
Free objects
For each drive object (max. 16), the following objects that can be freely interconnected are
available in the objects directory:
Table 1- 1
OD index (hex)
5800 to 580F
5810 to 581F
5820 to 5827
5828 to 582F
5830 to 5837
5838 to 5879
28
objects contain the data values for these parameters.
can be read or written.
If, for example, parameter r0062 of the setpoint velocity is to be read out from drive object
1, then:
– The switch must be set to "3" in parameter p8630 [0] (see previous diagram),
– The parameter r0062is converted to a hexadecimal value and 2000 hex is added. With
this hexadecimal number 203E hex, which corresponds to the object number, the
parameter r0062 can be accessed via an SDO request.
Note
The switch in parameter p8630 [0] determines the structure of the drive line-up. If an
Active Line Module (ALM) is not installed, the count for the first drive object starts with
"2". This number represents the drive ID.
The drive ID for each drive can be displayed with the parameter p8743[0...7] . The
drive ID for the first drive is in the index "0".
