If any of the above trips persist, please consult a Drive Centre.
If any changes are made to the drive's motor map parameters, system wiring,
NOTE
motor wiring configuration or motor type, the drive must be re-autotuned to the
motor. Not performing another autotune will result in poor motor performance,
OI.AC or It.AC trips.
OU - Overvoltage trip levels:
200V units - 420Vdc
400V units - 830Vdc
Braking levels:
200V units - 390Vdc
400V units - 780Vdc
UU - Undervoltage trip levels:
200V units - 180Vdc
400V units - 400Vdc
Reset from UU - Under voltage trip:
200V units - 235Vdc
400V units - 460Vdc
These are the absolute minimum DC voltages that the drive can be supplied by.

Condition
Possible loss of parameter values
Corruption due to severe electrical noise
Set default parameters (see parameter 29)
One of the input phases has become
disconnected from the drive. (This applies to
200V/400V three phase units only, not dual
rated units).
Motor cable disconnected during measurement
Motor too small for drive
See parameter 38 for more details
Bad connection or memory corrupt
New / empty Quickey being read
Quickey / drive software compatibility issue
Bad connection or faulty Quickey
Already programmed Quickey read by drive of
different rating
Overload of more than 110 mA or short circuit
on +28V serial communications power supply
Input current exceeded 25mA
Motor or motor connections changed. Check
motor connections and
re-autotune drive to motor (see parameter 38)
