Code Name Causes Possible Solutions End8 HFI Alarm Inductance saliency ratio (E5-07/E5-06) is too small. The drive cannot find the n8-36 [HFI Frequency Level for L Tuning] value. 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 it is necessary to set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-57 = 1 [HFI Overlap Selection = Enabled], make sure that there is no unusual noise in the low speed range (10% or less) and that the motor does not rotate in reverse at start. If there is unusual noise in the low speed range (10% or less), increase n8-41 in increments of 0.5. Set n8-41 > 0.0 for IPM motors. Note: If the drive detects End8, it will automatically set n8-35 =0 [Pull-in] and n8-57 = 0 [Disabled]. Do not change the settings unless necessary.
