Bad network quality on the
line side
Current is not flowing when
it should
Fieldbus communication
failure
Too low control supply
voltage
Too high motor temperature
Current is higher than
settable value during top of
ramp
Current is lower than
settable value during top of
ramp
This bit is set if a parameter
write operation failed due to
the parameter being read-
only.
Parameter is not
settable
This bit is set if a parameter
write operation failed due to
the parameter not being
settable (such as during a
soft start or soft stop).
Parameter value is out
of range
This bit is set if a parameter
write parameter operation
failed due to the set value
being out of range.
Extended diagnostic
available
If set, fault code provides
extended diagnostics.
This can be additional info
for a fault such as in which
phase the fault occurred or
the parameter number of the
latest read/write parameter
operation failure.
The diagnostic data is composed of a bit map of all potential faults and protections, as well as a flag, which
indicates if the active fault or protection can be reset. If ‘Parameter is read-only’, ‘Parameter not settable in
current state’ or ‘Parameter out of range’ bits are set, ‘Fault code’ contains the parameter number. ‘Parameter not
settable in current state’ can occur if the motor is running.
If ‘Extended diagnosis is available’ is set, ‘Fault code’ contains the Event information for the current event. For
events that can occur on a specific line, e.g., Phase loss, the value of the fault code will indicate the line number
the event occurred on. A ‘4’ indicates the line cannot be determined or the problem exists on all three phases.
