Ack. Fault: The unit considered has been stopped due to an error. By pressing
Ack. Fault, the reason for the fault will be displayed and an attempt will be made
to clear the fault. When doing this, the complete inverter system will be shut
down. If the fault could be cleared, the unit status will become ‘Ready’. If the fault
could not be cleared, the unit status will remain ‘Ack. Fault’. In the fault clearing
process, the complete inverter system will be shut down. The inverter can be
restarted after the fault clearing process has ended.
−
Not present: The unit considered has been excluded of the normal inverter
operation due to either:
•
The unit is physically not present
•
The unit is physically present but the control board power is not present
7.10.2 The ‘Inverter load’ menu
The inverter load menu shows bar graphs expressed in % indicating the inverter load
with respect to the nominal rating of the following parameters:
−
Inverter DC bus voltage: ‘Udc’ graph
−
Peak current of the IGBT-modules: ‘Ipeak’ graph
−
RMS current of the IGBT-modules: ‘Irms’ graph
−
IGBT-temperature: ‘Temp’ graph
For multi-unit inverters, this data can be obtained for each individual unit.
