Operating Instructions, 12/2014, A5E32923362A
No. Description
6B hex No change access for a closed-loop controller that is enabled (operating state of the in-
verter prevents a parameter change)
86 hex Write access only for commissioning (p0010 = 15) (operating state 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 availa-
ble)
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).
