The trips can be grouped into the following categories. It should be noted that a trip can only occur when the drive is not tripped or is already tripped
but with a trip with a lower priority number.

6 Self-resetting trips
Although the UV trip operates in a similar way to all other trips, all drive
functions can still operate but the drive cannot be enabled. The following
differences apply to the UV trip:
1. Power-down save user parameters are saved when UV trip is
activated except when the main high voltage supply is not active
(i.e. operating in Low Voltage DC Supply Mode, Pr 6.44 = 1).
2. The UV trip is self-resetting when the DC bus voltage rises above
the drive restart voltage level. If another trip is active instead of UV at
this point, the trip is not reset.
3. The drive can change between using the main high voltage supply
and low voltage DC supply only when the drive is in the under
voltage condition (Pr 10.16 = 1). The UV trip can only be seen as
active if another trip is not active in the under voltage condition.
4. When the drive is first powered up a UV trip is initiated if the supply
voltage is below the restart voltage level and another trip is not
active. This does not cause save power down save parameters to be
saved at this point.

Trips
These indicate serious internal problems and cannot be reset. The drive is inactive after
HF01 to HF16 one of these trips and the display shows HFxx. The Drive OK relay opens and the serial
comms will not function.
HF17 to HF32, SL1.HF,
Cannot be reset. Requires the drive to be powered down.
SL2.HF, SL3.HF
EEF Cannot be reset unless a code to load defaults is first entered in Pr xx.00 or Pr 11.43.
C.boot, C.Busy, C.Chg,
C.OPtn, C.RdO, C.Err,
Can be reset after 1.0s
