9. DeviceNet error codes
The following faults can occur if the DeviceNet module is used:
DeviceNet:

The duplicate MAC-ID check has
found two nodes with the same
MAC-ID.
Change the MAC-ID of one of the
nodes to a value which is not
already used.
DeviceNet:

supplied with 24 V DC.
In addition to the motor controller
the DeviceNet module must be
connected to 24 V DC.
DeviceNet:
RX queue overrun
Too many messages received within
a short period.
DeviceNet:
TX queue overrun
Not sufficient free space on the
CAN bus for sending messages.
Increase the baud rate, reduce the
number of nodes or reduce the scan

Check that the network is connected
correctly and has no faults.
The CAN controller is BUS OFF
Check that the network is connected
correctly and has no faults.

The CAN controller has an overrun.
Increase the baud rate, reduce the
number of customer nodes or
reduce the scan rate.

Please refer to the FHPP manual for detailed information.
Overrun/underrun or division by
zero during calculation of cyclic
data.
Check the cyclic data and/or check
the factor group.
FHPP:
Factor Group invalid
Calculation of the factor group leads
to invalid internal values.
FHPP:
