Auto-tuning error
(AUE)
Motor auto-tuning error
Action and Reset
Action level Hardware detection
Action time Immediately act
Fault treatment parameter N/A
Reset method Manual reset
Reset condition Immediately reset
Record Yes
Cause Corrective Actions
Press “STOP” key during
auto-tuning
Re-execute auto-tuning.
Incorrect motor capacity (too large
or too small) and parameter setting
Check motor capacity and related parameters.
Set the correct parameters, that is Pr.01-01–Pr.01-02.
Set Pr.01-00 larger than motor rated frequency.
Incorrect motor wiring Check the wiring.
Motor shaft lock Remove the cause of motor shaft lock.
The electromagnetic contactor is
ON at output side (U/V/W) of the
drive
Make sure the electromagnetic valve is OFF.
The load is too large.
Reduce the load.
Replace the motor with a larger capacity model.
Accel./Decel. time is too short Increase the setting values for Pr.01-12–Pr.01-19 (Accel./Decel. time).

PID loss ACI (AFE)
PID feedback loss (analog feedback signal is only valid
when the PID function is enabled)
Action and Reset
Action level When the analog input < 4mA (only detects 4–20mA analog input)
Action time Pr.08-08
Fault treatment parameter
Pr.08-09
0: Warn and keep operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: Warn and operate at last frequency
Reset method
Auto
When Pr.08-09=3 or 4, AFE is a “Warning”. When the feedback signal
is > 4mA, the ”Warning” is automatically cleared.
Manual When Pr.08-09=1 or 2, AFE is a “Fault”. You must reset manually.
Reset condition Immediately reset
Record
When Pr.08-09=1 or 2, AFE is a “Fault”, and the fault is recorded; when
Pr.08-09=3 or 4, AFE is a “Warning”, and the warning is not recorded.
Cause Corrective Actions
PID feedback cable is loose or cut
off Tighten the terminal.
Replace the cable with a new one.
Feedback device failure Replace the device with a new one.
Hardware failure Check all the wiring. If AFE fault still exists, return to the factory for repair.
