or the key was not replaced with one for the correct
hardware/software combination.
Recommended actions
Make sure the values in the configuration file match the installed
hardware. Make sure the configuration key match the installed
hardware/software combination. How to check the configuration
file is detailed in the Trouble Shooting Manual. If the capacitor
unit was recently replaced, make sure a unit of the correct type
code is used.
39410, Drive Unit communication warning
Description
Many communication errors are being detected between the
axis computer and drive unit number arg in drive module arg.
(error rate per time unit)
Consequences
If the number of communication errors increases further, there
is a risk that the controller will be forced to stop.
Probable causes
External noise may interfere with the communication signals.
Recommended actions
Check the communication link cable between the axis computer
and the main drive unit is correctly connected. Check that the
module is properly grounded. Check for external
electromagnetic noise sources close to the drive module.
39411, Too Many communication errors
Description
Four or more consecutive communication packets have been
lost between the axis computer and drive unit arg in drive
module arg.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
There may be a break in the communication link cable between
the axis computer and the main drive unit, the drive module
may be incorrectly grounded or excessive noise may interfere
with the communication signals.
Recommended actions
Check the communication link cable between the axis computer
and the main drive unit is correctly connected. Check that the
module is properly grounded. Check for external
electromagnetic noise sources close to the drive module.

39412, Too Many Missed Reference Updates
Description
Too many missed communication packets have been detected
for joint arg, in drive module arg.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
There may be a break in the communication link cable between
the axis computer and the main drive unit, the drive module
may be incorrectly grounded or excessive noise may interfere
with the communication signals.
Recommended actions
Check the communication link cable between the axis computer
and the main drive unit is correctly connected. Check that the
module is properly grounded. Check for external
electromagnetic noise sources close to the drive module.
39413, Drive Software Not Synchronized
Description
The axis computer software in drive module arg has become
unsynchronized with the drive software for joint arg. This is an
unstable software state.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
There may be glitches in the system timing.
Recommended actions
Restart the controller. If the problem persists, contact your local
ABB representative.
39414, Unknown Capacitor Type Code
Description
The type code for the capacitor unit arg in drive module arg is
not recognised by the system.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
The wrong type of capacitor unit may have been fitted or the
capacitor version used is not supported by the software.
