Code Name Causes Possible Solutions oPE10 V/f Data Setting Error The parameters that set the V/f pattern do not satisfy these conditions: For motor 1: E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04 [Minimum Output Frequency ≤ Mid Point A Frequency < Base Frequency ≤ Mid Point B Frequency ≤ Maximum Output Frequency] For motor 2: E3-09 ≤ E3-07 < E3-06 ≤ E3-11 ≤ E3-04 [Minimum Output Frequency ≤ Mid Point A Frequency < Base Frequency ≤ Mid Point B Frequency ≤ Maximum Output Frequency] Set the parameters correctly to satisfy the conditions.
