Cooling circuit connections
The electronics power supply is missing or lies outside permissible tolerance range.
The component is ready for operation and cyclic DRIVE-CLiQ communication is taking place.
The component is ready for operation and cyclic DRIVE-CLiQ communication is taking place.
The DC link voltage is present.
The component is ready for operation and cyclic DRIVE-CLiQ communication is taking place.
The DC link voltage is too high.
DRIVE-CLiQ communication is being established.
At least one fault is present in this component.
Note:
The LED is triggered independently from re-configuring the corresponding messages.
Firmware is being downloaded.
Firmware download is concluded. Wait for POWER ON.
Component detection using LED is activated (p0124).
Note:
Both options depend on the LED status when component recognition is activated via
p0124 = 1.
