3.4 Application
3.4.1 Communication Data Frame Structure
There is a correspondence between the parameters of the drive and the object
dictionary. You can easily and directly determine the object dictionary index
corresponding to a parameter based on a calculation method. This facilitates
operations on parameters.
Correspondence between the drive parameters and CANopen object dictionary
indexes
● Calculation method
The parameter groups correspond to the indexes 0x2000 to 0x20FF in the CANopen
object dictionary. The calculation method is as follows: An object dictionary index
is the upper 16 bits of the parameter address plus 0x2000; an object dictionary
sub‑index is the lower 16 bits plus 1.
For example, for drive parameter F0‑03, the communication address is 0xF003, and
the corresponding object dictionary index and sub‑index are 0x20F0 and 0x04,
respectively.
● Correspondence list
The parameter groups of the drive include groups F0 to FF, A0 to AF, and U0 to UF.
According to the preceding calculation method, for parameter read/write
operations, the correspondence between the parameter group numbers and the
object dictionary indexes is as follows:
