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
behavior of the application and can be displayed by the status messages with para-
meter
Controller status
275. The limit values and events which result in the inter-
vention by the corresponding controller are described in the corresponding chap-
ters.
sss
The behavior during the intervention of a controller is configured with the
parameter
Controller status message
409.
Operation mode 409 Function
0 - No message
The intervention of a controller is not reported.
The controllers influencing the operating behavior are
displayed in the
Controller status
275 parameter.
1 – Warning Status
The limitation by a controller is displayed as a warning
by the control unit.
11 – 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 14.3.7 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 fre-
quency inverter. The maximum output voltage of the compensation is set with para-
meter
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.
