Status Description
Off The electronics power supply is missing or outside the permissible tolerance
range.
Steady light The component is ready for operation and cyclic DRIVE-CLiQ
communication is taking place.
Steady light DRIVE-CLiQ communication is being established.
Steady light At least one fault is present in this component.
Note:
The LED is activated regardless of whether the corresponding messages
have been reconfigured.
Flashing Firmware is being downloaded.
0.5 Hz
Flashing Firmware download is being completed.
2 Hz Waiting for POWER ON.
Flashing Component recognition via LED is activated (p0144).
Note:
Both options depend on the LED status when component recognition is
activated via p0144 = 1.
Off The electronics power supply is missing or outside the permissible tolerance
range.
Power supply ≤ 5 V.
Steady light The electronics power supply for the measuring system is available.
Measuring system supply > 5 V
Notice:
You must ensure that the connected encoder can be operated with a 24 V
power supply.
If an encoder that is designed for a 5 V supply is operated with a 24 V
supply, this can destroy the encoder electronics.
