Parameter data transfer examples
The following example shows how parameter data is transferred
using the acyclic parameter access mechanism’s READ and
WRITE.
Note:
Only the part of the acyclic frame is presented in the
examples. The padding zeroes are not presented.
Example 1: Reading a drive parameter
To determine the parameter number and subindex for drive
parameter reading, multiply the parameter number by one
hundred and then convert it to hexadecimal. The low byte is the
subindex (IND), and the high byte is the parameter index (PNU).
For example, drive parameter number 12.04 corresponds to 12.04
× 100 = 1204 = 0x04B4.
Write request (Read parameter value):
01 01 B0 2F 0A 05 01 01 01 10 01 00 04 00 B4
