12.1 Trips, warnings and limits
In order to protect the AFR/AFG or VSI the principal
operating variables are continuously monitored by the
system. If one of these variables exceeds the safety limit an
error/warning message is displayed. In order to avoid any
possibly dangerous situations, the inverter sets itself into a
stop Mode called Trip and the cause of the trip is shown in
the display.
“Trip”
• The AFR/AFG/VSI stops immediately.
• The Trip relay or output is active (if selected).
• The Trip LED is on.
• The accompanying trip message is displayed.
• The “TRP” status indication is displayed (area D of the
display).
Apart from the TRIP indicators there are two more
indicators to show that the inverter is in an “abnormal”
situation.
“Warning”
• The AFR/AFG/VSI is close to a trip limit.
• The Warning relay or output is active (if selected).
• The Trip LED is flashing.
• The accompanying warning message is displayed in win-
dow [722] Warning.
• One of the warning indications is displayed (area F of
the display).
“Limits”
• The AFR/AFG/VSI is limiting torque and/or frequency
to avoid a trip.
• The Limit relay or output is active (if selected).
• The Trip LED is flashing.
• One of the Limit status indications is displayed (area D
of the display).
* Refer to Table 29 regarding which Desat or Power Fault is
triggered.
