9.6 List of fault codes and alarm codes
F07086
Units changeover: Parameter limit violation due to reference value change
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
A reference parameter was changed in the system. This resulted in the fact that for the parameters involved, the selected
value was not able to be written in the per unit notation.
The values of the parameters were set to the corresponding violated minimum limit/maximum limit or to the factory setting.
Possible causes:
- the steady-state minimum limit/maximum limit or that defined in the application was violated.
Fault value (r0949, parameter):
Diagnostics parameter to display the parameters that were not able to be re-calculated.
See also: p0304, p0305, p0310, p0596, p2000, p2001, p2002, p2003, r2004
Remedy:
Check the adapted parameter value and if required correct.
See also: r9450 (Reference value change parameter with unsuccessful calculation)
F07088
Units changeover: Parameter limit violation due to units changeover
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
A changeover of units was initiated. This resulted in a violation of a parameter limit
Possible causes for the violation of a parameter limit:
- When rounding off a parameter corresponding to its decimal places, the steady-state minimum limit or maximum limit was
violated.
- inaccuracies for the data type "FloatingPoint".
In these cases, when the minimum limit is violated then the parameter value is rounded up and when the maximum limited
is violated the parameter value is rounded down.
Fault value (r0949, interpret decimal):
Diagnostics parameter r9451 to display all parameters whose value had to be adapted.
See also: p0100 (IEC/NEMA Standards), p0505 (Selecting the system of units), p0595 (Technological unit selection)
Remedy:
Check the adapted parameter values and if required correct.
See also: r9451 (Units changeover adapted parameters)
A07089
Changing over units: Function module activation is blocked because the units have been changed
over
Reaction:
NONE
Acknowledge:
NONE
Cause:
An attempt was made to activate a function module. This is not permissible if the units have already been changed over.
See also: p0100 (IEC/NEMA Standards), p0505 (Selecting the system of units)
Remedy:
Restore units that have been changed over to the factory setting.
A07094
General parameter limit violation
Reaction:
NONE
Acknowledge:
NONE
Cause:
As a result of the violation of a parameter limit, the parameter value was automatically corrected.
Minimum limit violated --> parameter is set to the minimum value.
Maximum limit violated --> parameter is set to the maximum value.
Alarm value (r2124, interpret decimal):
Parameter number, whose value had to be adapted.
Remedy:
Check the adapted parameter values and if required correct.
A07200
Drive: Master control ON command present
Reaction:
NONE
