9.7.2.2
Addressing by means of index and subindex
A parameter (a Lenze code) is addressed as per the following formula:
Index = 24575 - (Lenze code number)
Example
parameter (motor reference speed) is to be addressed.
Calculation:
• Index:
• Decimal: 24575 - 11 = 24564
• Hexadecimal: 0x5FFF - 0xB = 0x5FF4
• Subindex: 0x00 (subindex 0 since the parameter does not have any subcodes)
