State Description
Off Electronics power supply outside permissible tolerance range
Steady light The component is ready for operation and cyclic DRIVE-CLiQ
communication is taking place.
Flashing light Writing to CompactFlash card
2 Hz
Steady light At least one fault is present in this component.
Flashing light CompactFlash card has not been inserted.
0.5 Hz Boot error (e.g. firmware cannot be loaded to the RAM).
Flashing light Control Unit 310 DP is ready for operation.
0.5 Hz No software licenses for device.
Steady light DRIVE-CLiQ communication is being established.
Flashing light Unable to load firmware to RAM
0.5 Hz
Flashing light Firmware CRC error
2 Hz
Off Cyclic communication is not (yet) running.
Note:
The PROFIBUS is ready for communication when the Control Unit is
ready for operation (see RDY LED).
Steady light Cyclic communication is running.
Flashing light Cyclic communication is not yet running fully.
0.5 Hz Possible reasons:
The master is not transmitting setpoints.
•
No global control (GC) or master sign-of-life is transmitted during
•
isochronous operation.
Steady light Cyclic communication has been interrupted.
Off Electronics power supply is missing or outside permissible tolerance
range.
Power supply ≤5 V.
Electronics power supply for measuring system available.
Power supply >5 V.
Notice
Steady light
You must ensure that the connected encoder can be operated with a
24 V 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.
