Auxiliary frequency values
Definition of up to 3 frequency points, which define the monitoring range for load monitoring. The
auxiliary frequency values do not need to be entered in order of size. Prefixes are not taken into
account, only the integer values are processed (motor / generator torque, right/left rotation). The
array elements [-01], [-02] and [-03] of parameters (P525) … (P527), or the entries which are
made there always belong together.

Parameter (P528) defines the delay time for which an error message ("E12.5") is suppressed on
infringement of the defined monitoring range ((P525) … (P527)). A warning ("C12.5") is triggered
after half of this time has elapsed.
According to the selected monitoring mode (P529) an error message can also be generally
suppressed.

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").

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.
