Status
OFF The electronics power supply is missing or lies outside the
permissible tolerance range.
Continuous The component is ready for operation and cyclic DRIVE-CLiQ
communication is taking place.
Continuous DRIVE-CLiQ communication is being established.
Continuous At least one fault is pending on this component.
Note:
LED is driven irrespective of the corresponding messages being
reconfigured.
0.5 Hz flashing light Firmware is being downloaded.
2 Hz flashing light Firmware download is complete. Wait for POWER ON.
2 Hz flashing light Detection of the components via LED is activated (p0144).
Note:
Both options depend on the LED status when module recognition is
activated via p0144 = 1.
State
OFF The electronics power supply is missing or lies outside 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 pending on this component.
Note:
LED is driven irrespective of the corresponding messages being
reconfigured.
0.5 Hz flashing light Firmware is being downloaded.
2 Hz flashing light Firmware download is complete. Waiting for POWER ON.
2 Hz flashing light Detection of the components via LED is activated (p0144).
Note: Both options depend on the LED status when module
recognition is activated via p0144 = 1.
OFF Electronic power supply missing or outside permissible tolerance
range.
Measuring system supply ≤ 5 V (only when ready for operation).
Steady light Electronic power supply for measuring system present.
Measuring system supply > 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.
