Re-execute auto-tuning.
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.
Check the wiring.
Remove the cause of motor shaft lock.
Make sure the electromagnetic valve is OFF.
Reduce the load.
Replace the motor with a larger capacity model.
Increase the setting values for Pr. 01-12–Pr. 01-19 (Accel./Decel. time).
Fault Name
PID feedback loss (analog feedback signal is only valid
PID loss ACI (AFE)
when the PID function is enabled)
Action and Reset
When the analog input < 4mA (only detects 4–20mA analog input)
Pr. 08-08
Pr. 08-09
0: warn and keep operation
1: warn and ramp to stop
2: warn and coast to stop
3: warn and operate at last frequency
When Pr. 08-09=3 or 4, AFE is a "Warning". When the feedback signal
Auto
is > 4mA, the "Warning" is automatically cleared.
Manual When Pr. 08-09=1 or 2, AFE is a "Fault". You must reset manually.
Immediately reset
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.
Tighten the terminal.
Replace the cable with a new one.
Replace the device with a new one.
Check all the wiring. If AFE fault still exists, return to the factory for repair.
