10.3 Fieldbus fault codes
Option board can report only Fieldbus communications fault (F53). This does not identify what
actually went wrong and why option board activated this fault. To that end, more information is now
added to fault activation. Currently this works only with VACON
®
100 family AC drives.
In VACON
®
100 family AC drive with default applications when fieldbus fault is activated (F53
specifically), new information is added to the faults "source" fields if the source fields are empty.
The following table contains "source 3" additional fault codes. Notice that all subcodes listed here
are not applicable for all fieldbuses/option boards.
Table 204. Description of the fault fields
Fault field Descriptions
Source 1 Activation source. Always "Control"
Source 2 Slot where option board is installed (slot D or slot E)
Source 3 Additional fault code
Table 205. Additional fault codes
Fault code Fault name Description
1 IO watchdog IO connection timeout noticed by watchdog
2 IO master closed connection IO connection was closed (gracefully) by master
3EM watchdog
Explicit messaging connection timeout noticed by
watchdog
4 EM master closed connection
Explicit messaging connection was closed (gracefully)
by master
5 Cable disconnected
Fieldbus cable was disconnected after communica-
tions had been started
6 Cable not connected Fieldbus cable was not connected after device startup
7IOPS changed to BAD
PROFINET IO master data status changed from GOOD
to BAD
8 Idle state activated
EtherNet/IP IO connection status changed to IDLE
when motor is been controlled
9 Internal system fault

speed reference to drive format
