{ 0 } The reaction of the frequency inverter to an infringement of the defined monitoring range ((P525)
… (P527)) after the elapse of the delay time (P528) is specified by parameter (P529).
0 = Fault and warning , After the elapse of the time defined in (P528), an infringement of the
monitoring range produces a fault ("E12.5"). A warning ("C12.5") is given after the elapse
of half of this time.
1 = Warning , After the elapse of half of the time defined in (P528) and infringement of the
monitoring range produces a warning ("C12.5").
2 = Error and warning, constant travel , " Error and warning during constant travel ", as for
setting "0" however monitoring is inactive during acceleration phases.
3 = Warning constant travel , " Only warning during constant travel ", as for setting "1",
however monitoring is inactive during acceleration phases.
P525 … P529 Load monitoring
With the load monitoring, a range can be specified within which the load torque may change
depending on the output frequency. There are three auxiliary values for the maximum permissible
torque and three auxiliary values for the minimum permissible torque. A frequency is assigned to
each of these auxiliary values. No monitoring is carried out below the first and above the third
frequency. In addition, the monitoring can be deactivated for minimum and maximum values. As
standard, monitoring is deactivated.
The time after which a fault is triggered can be set with parameter (P528). If the permissible
range is exceeded (Example diagram: Infringement of the area marked in yellow or gree n ), the
error message
E12.5
is generated unless parameter (P529) does not suppress the triggering of
an error.
