3.4.5.1 Example: Write a parameter
The acceleration time C0012 of the drive controller with the device address 1 is to be altered from
1 to 20 sec through parameter channel 1.
Calculation of identifier:
Identifier from parameter channel 1 to drive controller = 1536 + device address = 1536 + 1 = 1537
Command code = Write Request (transmit parameter to drive)= 23
hex
Calculation of the index
Index = 24575 - code no. = 24575 - 12 = 24563 = 5FF3
hex
Subindex for C0012 = 0
Calculation of the value for the acceleration time
20 sec ⋅ 10.000 = 200.000 = 00030D40
hex
