Error Meaning
value 1
73 hex Change request possible only during commissioning of the safety functions (p0010 = 95).
74 hex Change request is only possible when a technological application/unit is being commissioned (p0010 = 5).
75 hex Change request is only possible in a commissioning state (p0010 ≠ 0).
76 hex Change request is not possible for internal reasons (p0010 = 29).
77 hex Change request is not possible during download.
81 hex Change request is not possible during download.
82 hex Accepting the master control is inhibited via BI: p0806.
83 hex Desired interconnection is not possible(the connector output does not supply a float value although the con-
nector input requires a float value)
84 hex Inverter does not accept a change request (inverter is busy with internal calculations. See parameter r3996 in
the inverter List Manual.
Manuals for your inverter (Page 272))
85 hex No access methods defined.
86 hex Write access only during commissioning of the data records (p0010 = 15) (operating status of the inverter pre-
vents 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)
