Priority Category Trips Comments
1 Internal faults HF01 - HF19
These are fatal problems that cannot be reset. All drive features are inactive after any of these trips occur. If a basic
keypad is fitted it will show the trip, but the keypad will not function. These trips are not stored in the trip log.
1 Stored HF trip StoredHF This trip cannot be cleared unless 1299 is entered into Parametermm.000 (mm.000) and a reset is initiated.

PhaseLoss and
OHtdcbus
The drive will attempt to stop the motor before tripping if a PhaseLoss.000 trip occurs unless this feature has been
disabled (see ActionOnTripDetection (10.037)). The drive will always attempt to stop the motor before tripping if
an OHtdcbus occurs.
5 Standard trips All other trips
Trips {HF01} to {HF19} are internal faults that do not have trip numbers. If one of these trips occurs, the main drive processor has detected an irrecoverable error. All
drive functions are stopped and the trip message will be displayed on the drive keypad. The error can only be reset by powering the drive down and up again. The
table below gives the reasons for internal faults and their corresponding trip
