14
DL Login
The adapter has logged into a Datalink.
15
DL Reject Flt
(5)
The drive rejected an attempt to log in to a Datalink because the Datalink is not supported or is used by
another peripheral.
16
DL Time Flt
The adapter has not received a Datalink message within the specified time.
17
Control Disabled
The adapter has sent a “Soft Control Disable” command to the drive.

The adapter successfully started up.
23
NET Comm Flt
(7)
The adapter detected a communications fault on the network.
24
Flt Cfg Error
(8)
The adapter detected a 32-bit fault configuration reference when the drive supports only a 16-bit reference,
or the adapter detected a 32-bit fault configuration Datalink value when the drive supports only 16-bit
Datalinks.
25
COPN Guard Err
The node has not been guarded by an NMT master with the Guard Time x LifeTime Factor period.
(Enabled if Guard Time <> 0.)
26
COPN Operational
The adapter has received a “Start_Remote_Node” message from the bus.
27
COPN Stopped
(9)
The adapter has received a “Stop_Remote_Node” message from the bus.

Adapter Actions Upon Events:
(1)
The adapter is reset.
(2)
The adapter awaits a reconfiguration and a reset.
(3)
The adapter is locked in the state where the PORT status indicator is steady orange and waits a reset.
(4)
The adapter is locked in a fault state and awaits reset.
(5)
As many I/O connections as possible are completed. The adapter waits a reconfiguration and a reset.
(6)
An event is logged. (Client-Server is not used for control, so it does not need to be a fault.)
(7)
The communication fault action specified in Parameter 10 - [Comm Flt Action] is performed.
(8)
The drive is forced to fault and, thereafter, only “No Operation” commands are sent to the drive until the fault configuration data has been corrected.
(9)
The idle fault action specified in Parameter 11 - [Idle Flt Action] is performed.
(10)
The communication fault action specified in Parameter 10 - [Comm Flt Action] is performed and the CANopen communication parameters are set to their
default values.
