Parameter Selection Error

You set a function that is not compatible with the control method set in A1-02 [Control Method Selection].

  1. Push [ENTER Key] to show U1-18 [oPE Fault Parameter], and find parameters that are not in the applicable setting range.

  2. Correct the parameter settings.

    Note:

    If more than one error occurs at the same time, other oPExx errors have priority over oPE02.

When A1-02 = 2 [Control Method Selection = OLV], you used these parameter settings:

  • n2-02 > n2-03 [Automatic Freq Regulator Time 1 > Automatic Freq Regulator Time 2]

  • C4-02 > C4-06 [Torque Compensation Delay Time > Motor 2 Torque Comp Delay Time]

  • Set n2-02 < n2-03.

  • Set C4-02 < C4-06.

When A1-02 = 0 [Control Method Selection = V/f], you used these parameter settings:

  • H6-01 = 3 [Terminal RP Pulse Train Function = Speed Feedback (V/F Control)]

  • H1-xx = 16 [MFDI Function Select = Motor 2 Selection]

Correct the parameter settings.

Note:

You cannot use Speed Feedback (V/F Control) with the Motor Switch function.

When A1-02 = 5 [PM Open Loop Vector], you set E5-02 to E5-07 [PM Motor Parameters] = 0.

  • Set E5-01 [PM Motor Code Selection] correctly as specified by the motor.

  • For specialized motors, refer to the motor test report and set E5-xx correctly.

When A1-02 = 5 to 7 [Control Methods for PM Motors], you used these parameter settings:

  • E5-09 = 0.0 [PM Back-EMF Vpeak (mV/(rad/s)) = 0.0 mV/(rad/s)]

  • E5-24 = 0.0 [PM Back-EMF L-L Vrms (mV/rpm) = 0.0 mV/min-1]

Set E5-09 or E5-24 to the correct value.

When A1-02 = 5 to 7, you set E5-09 ≠ 0 and E5-24 ≠ 0.

Set E5-09 = 0 or E5-24 = 0.

When A1-02 = 6 [PM Advanced Open Loop Vector], you used these parameter settings:

  • n8-57 = 0 [HFI Overlap Selection = Disabled]

  • You set E1-09 [Minimum Output Frequency] < the 5% value of E1-06.

Correct the parameter settings.

When A1-02 = 6, you set these parameters:

  • n8-35 = 0 [Initial Pole Detection Method = Pull-in]

  • n8-57 = 1 [Enabled]

Correct the parameter settings.

When A1-02 = 8 [EZOLV], you used these parameter settings:

  • E9-01 = 1, 2 [Motor Type Selection = Permanent Magnet (PM), Synchronous Reluctance (SynRM)]

  • b3-24 = 2 [Speed Search Method Selection = Current Detection 2]

When E9-01 = 1 or 2, set b3-24 = 1 [Speed Estimation].
