Auto-tuning error
Action and Reset
1. When detecting stator resistance, output current is smaller than 5% of the drive's
rated current and time exceeds 0.5 sec.
2. Incorrect encoder signal for PGHH during auto-tuning.
0.5 sec.
Manual reset
Resets immediately
Yes
Re-execute auto-tuning.
Verify motor specification and set motor parameter settings again (Pr.00-10–Pr.00-16).
Check the wiring.
Remove the cause of motor shaft lock.
Make sure the magnetic contactor is Closed.
Reduce the load.
Replace the motor with a larger capacity model.
1. Check if the A/B/C/D wiring is correct.
2. Check if the signal line of the encoder is interfered.

Opposite PG feedback
direction
Action and Reset
1. Encoder input type does not set (Pr.00-23 = 0)
2. Feedback direction is opposite to the frequency command direction
Pr.04-71 Encoder Feedback Signal Fault Detection Time (Default: 1.0 second)
Pr.04-70 (Default: 2)
0: Warn and keep operation
1: Fault and ramp to stop
2: Fault and stop operation
Auto When Pr.04-70=0, PGF1 is a warning and will be automatically cleared.
Manual When Pr.04-70=1 or 2, PGF1 is a fault and must be reset manually.
Resets immediately
If PGF1 is a warning, it will not be recorded.
If PGF1 is a fault, it will be recorded.
Set encoder parameter settings again (Pr.00-23)
Ensure the A/B wiring is correct.
Motor auto-tuning error
Corrective Actions
The motor runs in a reverse direction to the
frequency command direction, and the time
error occurred exceeds Pr.04-71 detection
time.
Corrective Actions
9-32
