- Cause
- The drive cannot calculate the correct value for n8-84 [Polarity Detection Current] during High Frequency Injection Tuning. verified
- Corrective action
- • Set the correct value on the motor nameplate E5-xx [PM motor parameters] or do Stationary/Rotational Auto-Tuning, and then do High Frequency Injection Tuning again. • When n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-57 = 1 [HFI Overlap Selection = Enabled], make sure that the motor does not rotate in reverse at start. verified
