Response (Lenze setting printed in bold) Setting: C13891/3 / C14891/3
 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
In the Controlled Node, the synchronisation cycle of the
Managing Node has failed. The Controlled Node changes
automatically to the NMT_CS_PREOPERATIONAL_1
state and waits for a new run-up by the Managing Node.
• Check wiring components (failure of Managing Node,
router).
• Restart Managing Node if required.
• Change CN monitoring thresholds via C13127 /
C14127 .

 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
Faulty Ethernet frames (CRC error) have been detected.
Possible causes:
• A device an the network is not POWERLINK-
compliant.
• EMC interference is too strong.
• Check if a non-POWERLINK-compliant device is in the
network (e.g. diagnostics PC).
• Reduce EMC interference on the network or use an
additional shield connection.
• Change monitoring thresholds:
• Managing Node: C13115/3 / C14115/3
• Controlled Node: C13131/3 / C14131/3

 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
In case of the Managing Node, an unwanted change
from the "Operational" status has occurred due to an
error. Possible causes are:
• Node failure
• Network cables have been detached.
• Servo Drive 9400 is switched off.
• Communication module is defective.
• Time-out with Controlled Nodes
• Telegram collisions due to non-compliant
POWERLINK nodes
• Check wiring.
• Plug network cable into POWERLINK terminal X211 or
X212.
• Restart Managing Node if required.
• Switch on Servo Drive 9400.
• POWERLINKCheck if a non--compliant device is in the
network (e.g. diagnostics PC).
• Check whether collisions have occurred with the
Managing Node ( C13126 / C14126 ).
• Change CN monitoring thresholds ( C13124 /
C14124 ).

description of the fault to Lenze.
Response (Lenze setting printed in bold) Setting: C13891/1 / C14891/1
 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
The Managing Node has detected that the previous cycle
has not yet been completed when the new cycle starts.
Select a larger POWERLINK cycle time via C13060 /
C14060 .
