LEDs and other status indicators

This section instructs how to interpret the status indications of the ACS880-207 IGBT
supply unit.
Warnings and faults reported by the control program are displayed on the control panel on
the cabinet door. For further information, see the firmware manual delivered with the IGBT
supply unit.
The ACS-AP-W control panel has a status LED. The control panel mounting platform has
two LEDs - a red and a green one. The IGBT supply module has three LEDs. For their
indications, see the following table.
