Fault Descriptions
Motor overheating
The AC motor drive
detecting internal
temperature exceeds the
setting of Pr.06-30 (PTC
level) or Pr.06-57 (PT100
level 2).
These two fault codes will
be displayed when output
current exceeds the
over-torque detection
level (Pr.06-07 or
Pr.06-10) and exceeds
over-torque detection
(Pr.06-08 or Pr.06-11)
and it is set to 2 or 4 in
Pr.06-06 or Pr.06-09.
Low current detection
Limit error
Internal EEPROM can not
be programmed.
Internal EEPROM can not
be read.
U-phase error
V-phase error
W-phase error
Corrective Actions
1. Make sure that the motor is not obstructed.
2. Ensure that the ambient temperature falls within
the specified temperature range.
3. Change to a higher power motor.
1. Check whether the motor is overloaded.
2. Check whether motor rated current setting
(Pr.05-01) is suitable
3. Take the next higher power AC motor drive
model.
Check Pr.06-71, Pr.06-72, Pr.06-73.
1. Press "RESET" key to the factory setting
2. Return to the factory.
