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 PN 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
Cyclic communication is not (yet) running.
Note:
Off
The PROFINET is ready for communication when the Control Unit is
ready for operation (see RDY LED).
Steady light
Cyclic communication is running.
Cyclic communication is not yet running fully.
Possible reasons:
Flashing light
The master is not transmitting setpoints.
0.5 Hz
•
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.
