Parameter identifier (PKE), first word
The parameter identifier (PKE) is always a 16-bit value.
Figure 9-50
● Bits 0 to 10 (PNU) contain the remainder of the parameter number (value range 1 to
For parameter numbers ≥ 2000, an offset must be added that is defined using the upper bits
of the IND byte.
● Bit 11 (SPM) is reserved and always = 0.
● Bits 12 to 15 (AK) contain the request or response identifier.
The significance of the request identifier for request telegrams (master → inverter) is
described in the following table.

1) The required element of the parameter description is specified in IND (second word).
2) Identifier 1 is identical to identifier 6, ID 2 is identical to 7, and 3 is identical to 8. We recommend
that you use identifiers 6, 7, and 8.
The significance of the response identifier for response telegrams (inverter → master) is
described in the following table. The request identifier determines which response identifiers
are possible.
