State
Description
READY --- OFF The electronic power supply is missing or lies outside the permissible
tolerance range.
Green Continuous light The component is ready for operation and cyclic DRIVE-CLiQ communi-
cation is taking place.
Orange
Continuous light
DRIVE-CLiQ communication is being established.
Red Continuous light This component has at least one fault.
Remark:
The LED is activated irrespective of whether the corresponding messag-
es have been reconfigured.
Green/red 0.5 Hz flashing
light
Firmware is being downloaded.
2 Hz flashing
light
Firmware download is complete. Waiting for POWER ON.
Green / orange
or
red / orange
Flashing light Detection of the components via LED is activated (p0144).
Remark:
Both options depend on the LED status when module recognition is acti-
vated via p0144 = 1.
OUT>5 V --- OFF The electronic power supply is missing or lies outside the permissible
tolerance range.
Power supply ≤ 5 V.
Orange Continuous light Electronic power supply for measuring system present.
Supply voltage > 5 V.
Notice:
You must ensure that the connected encoder can be operated with a 24
V supply.
Operating an encoder designed for a 5 V supply with a 24 V supply can
damage the encoder electronics beyond repair.
