End9

Initial Pole Detection Alarm

The drive cannot calculate the correct value for n8-84 [Polarity Detection Current] during High Frequency Injection Tuning.

  • 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.

    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 End9, it will automatically set n8-35 =0 [Pull-in] and n8-57 = 0 [Disabled]. Do not change the settings unless necessary.
