14.3 Controller Status
The intervention of a controller can be indicated via the control unit or LED's. The selected control
methods and the matching monitoring functions prevent a switch-off of the frequency inverter. The
intervention of the function changes the operating behavior of the application and can be displayed
by the status messages with parameter Controller Status 275. The limit values and events which
result in the intervention by the corresponding controller are described in the corresponding
chapters. The behavior during the intervention of a controller is configured with parameter
Controller-Status Message 409.
Controller-Status
Message 409
The intervention of a controller is not reported.
The controllers influencing the operating behavior are displayed in the
Controller status 275 parameter.
The limitation by a controller is displayed as a warning by the control
unit.
The limitation by a controller is displayed as a warning by the control
unit and the LED's.
Refer to Chapter 16.3.8 "16.3.8" and Chapter 16.3.8 "16.3.8" for a list of controllers and additional
controller status evaluation options.
14.4 IDC Compensation Limit
At the output of the frequency inverter a DC component can occur in the output current due to
unbalances. This DC voltage component can be compensated by the frequency inverter. The
maximum output voltage of the compensation is set with parameter IDC Compensation Limit 415.
If a higher voltage than the set limit is needed for the compensation of a DC voltage component,
error “F1301 IDC COMPENSATION“ is triggered.
If this fault occurs, it should be checked whether the load is defective. The voltage limit may have to
be increased.
If the parameter IDC Compensation Limit 415 is reduced to zero, the DC compensation is
deactivated.
The factory setting of parameter IDC Compensation Limit 415 depends on the setting of parameter
