Faults and Alarms
List of Faults and Alarms
F07083 Macro: ACX file not found
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The ACX file (macro) to be executed was not able to be found in the appropriate directory.
Fault value (r0949, decimal interpretation):
Parameter number with which the execution was started.
See also: p0015, p0700, p1000, p1500
Remedy: - check whether the file is saved in the appropriate directory on the memory card.
F07084 Macro: Condition for WaitUntil not fulfilled
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The WaitUntil condition set in the macro was not fulfilled in a certain number of attempts.
Fault value (r0949, decimal interpretation):
Parameter number for which the condition was set.
Remedy: Check and correct the conditions for the WaitUntil loop.
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 representation (cause: e.g. the steady-state
minimum/maximum limit or that defined in the application was violated). The values of the parameters were set to
the corresponding violated minimum/maximum limit or to the factory setting.
Fault value (r0949, parameter):
Diagnostics parameter r9450 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.
F07088 Units changeover: Parameter limit violation due to units changeover
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: A changeover of units was initiated.
Possible causes for the violation of a parameter limit are:
- when rounding off a parameter corresponding to its decimal places, the steady-state minimum 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, decimal interpretation):
Diagnostics parameter r9451 to display all parameters whose value had to be adapted.
See also: p0100 (IEC/NEMA mot stds), p0505 (Selecting the system of units), p0595 (Selecting technological units)
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 mot stds), p0505 (Selecting the system of units)
Remedy: Restore units that have been changed over to the factory setting.
