LED state
Description
READY
DC LINK
Off Off The electronics power supply is missing or outside the permissible tolerance
range.
Green
Off The component is ready for operation and cyclic DRIVE-CLiQ communication is
taking place.
Orange The component is ready for operation and cyclic DRIVE-CLiQ communication is
taking place. The DC-link voltage is present.
Red The component is ready for operation and cyclic DRIVE-CLiQ communication is
taking place. The DC-link voltage is too high.
Orange
Orange
DRIVE-CLiQ communication is being established.
Red --- At least one fault is present in this component.
Note:
The LED is activated regardless of whether the corresponding messages have
been reconfigured.
Green/Red
(0.5 Hz)
–-- Firmware is being downloaded.
Green/Red
(2 Hz)
--- Firmware download is complete. Wait for POWER ON.
Green/orange
or
red/orange
--- Recognition of the component via LED is activated (see SINAMICS S120/S150
List Manual)
Note:
Both options depend on the LED status when component recognition is activated
using the parameter.
WARNING
Danger of death when live parts of the DC link are touched
Irrespective of the state of the LED "DC LINK", hazardous DC-link voltages can be present.
This means the touching of live parts can result in death or serious injury.
• Observe the warning information on the component.
