6.2.3 Write parameter
The acceleration time C0012 (parameter set 1) of the controller with address 1 is to be changed to
20 s via parameter channel 1.
• Identifier calculation
Identifier parameter channel 1 to controller = 1536 + controller address
Identifier = 1536 + 1 = 1537
• Command write request (send parameter to drive)

hex
• Index calculation
Index = 24575 - code number - 2000 (PS - 1) Index = 24575 - 12 - 2000 V 0 = 24563 = 5FF3
