12.3 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 be-
havior of the application and can be displayed by the status messages with parame-
ter
Controller status 275
. The limit values and events which result in the intervention
by the corresponding controller are described in the corresponding chapters.

Warning status and
LED
The limitation by a controller is displayed as a warning
by the control unit and the LED's.
Refer to chapter 14.3.8 Warning Mask and 20.3 Controller Status for a list of control-
lers and further possibilities to evaluate the controller states.
12.4 IDC Compensation Limit
At the output of the frequency inverter a DC component can occur in the output cur-
rent due to unbalances. This DC voltage component can be compensated by the
frequency inverter. The maximum output voltage of the compensation is set with pa-
rameter
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 COMPENSA-
TION“ 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 compensa-
tion is deactivated.
