39426, Rectifier internal failure
Description
The rectifier on communication link arg attached to drive module
arg has detected an internal failure.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
This may be caused by a faulty or lacking signal connection
between the rectifier and drive units.
Recommended actions
Make sure the signal cable is correctly connected between the
rectifier and drive unit. Check the indication LEDs on the rectifier
and drive units. The significance of the LEDs is described in
the Trouble Shooting Manual.
39427, Rectifier communication missing
Description
The communication with the rectifier on drive communication
link arg, drive module arg has been lost.
Consequences
No operation will be possible until after correcting the fault. The
system goes to status SYS HALT.
Probable causes
This may be caused by a faulty or lacking signal connection
between the rectifier and drive units.
Recommended actions
Make sure the signal cable is correctly connected between the
rectifier and drive unit. Perform a shutdown and then restart
the controller. If the problem persists, isolate the faulty unit and
replace it.
39428, Rectifier startup error
Description
The rectifier on drive communication link arg, drive module arg
has detected a startup error.
Consequences
