No.
Description
6A hex
Request not included / task is not supported
(the valid request identifications can be found
in table "Request identifications controller → inverter")
6B hex
No change access for a controller that is enabled
(operating status of the inverter prevents
a parameter change)
86 hex
Write access only for commissioning (p0010 = 15)
(operating status of the inverter
prevents a parameter change)
87 hex
Know-how protection active, access locked
C8 hex
Change request below the currently valid limit
(change request to a value that lies within
the "absolute" limits, but is however below the currently valid lower limit)
C9 hex
Change request above the currently valid limit
(example: a parameter value is too large for
the inverter power)
CC hex
Change request not permitted
(change is not permitted as the access code is not
available)
Parameter number
Parameter numbers < 2000
PNU = parameter number.
Write the parameter number into the PNU (PKE bit 10 ... 0).
Parameter numbers
≥ 2000
PNU = parameter number
- offset.
Write the parameter number minus the offset into the PNU
(PKE bit
10 … 0).
Write the offset in the page index (IND bit 15 … 8).

Indexed parameters
For indexed parameters, you must write the index as hex value into the subindex
(IND bit 7 … 0).
