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

C011

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)
